- [X] I added a very descriptive title to this issue.
- [X] I searched the LangChain documentation with the integrated search.
- [X] I used the GitHub search to find a similar question and didn't find it.
### Example Code
```
# No code provided
# LangSmith trace link in Description
```
### Description
I test a sample code of CrewAI, which is based on Langchain and I found, again :( that tool_input is incorrectly set, which causes incorrect answers.
I track it in LangSmith and here is the RunnableSequence's input:
```
input: Investigate which AI / LLM assisted IDE assistant can assist coding related questions not only related to the selected code or the opened file, but all the project code files, the console and terminal messages. Check also the most recent IDEs, not only the most popular ones. Your final answer MUST be a full analysis report
tool_names: Google Search
tools: "Google Search: Search Google for recent results."
chat_history: ""
intermediate_steps: []
```
and output:
```
output:
tool: Google Search
tool_input: AI / LLM assisted IDE assistant for coding related questions
log: |-
Thought: Do I need to use a tool? Yes
Action: Google Search
Action Input: "AI / LLM assisted IDE assistant for coding related questions"
type: AgentAction
```
so we can see the original task of:
_**"Investigate which AI / LLM assisted IDE assistant can assist coding related questions not only related to the selected code or the opened file, but all the project code files, the console and terminal messages. Check also the most recent IDEs, not only the most popular ones. Your final answer MUST be a full analysis report"**_
was transformed to a Google search for:
_**"AI / LLM assisted IDE assistant for coding related questions"**_
which obviously doesn't provide the search results relevant to original task!
The trace with Zephyr-7B via Hugging Face: https://smith.langchain.com/public/d4076fff-78d7-48ab-bdfe-d463bd1ffcb3/r
The same with gpt-4: https://smith.langchain.com/public/1fa8da61-6cc9-448c-8aa3-fd75d930e623/r
**So what and where should we finetune, modify to keep search term or any other tool_input correct, without huge distortion?**

- [X] I added a very descriptive title to this issue.
- [X] I searched the LangChain documentation with the integrated search.
- [X] I used the GitHub search to find a similar question and didn't find it.
### Example Code
I implemented a custom retriever like this:
```
class CustomUserRetriever(BaseRetriever):
vectorstore: VectorStore
username: str # New attribute to store the filename
def clean_metadata(self, doc):
metadata = doc.metadata
return { # Add a button to clear chat history
"Title": metadata["title"],
"source": metadata["title"],
"chunk_id": metadata["chunk_id"]
}
def get_relevant_documents(self, query):
docs = []
for doc in self.vectorstore.similarity_search(query, search_type="hybrid", k=5, filters=f"search.ismatch('{self.username.split('@')[0]}', 'usernames_result') "):
cleaned_metadata = self.clean_metadata(doc)
docs.append(Document(
page_content=doc.page_content,
metadata=cleaned_metadata))
return docs
```
And then I created a custom functionality which should return the answer, and the source of the answer. (document name with extension)
```
retriever = CustomUserRetriever(vectorstore=vector_store, username=user_name)
chain = RetrievalQAWithSourcesChain.from_chain_type(llm,
chain_type="stuff",
memory=memory,
retriever=retriever,
return_source_documents=True
)
#result = chain({"question": user_question})
result = chain({"question":user_question}, return_only_outputs=True)
```
THen I ask a question which should get a response from 2 document chunks, and the answer is generated correctly.
However asking the same question multiple times, sometimes I get an empty source and sometimes I get a list of the source documents,
### Description
I want to get answers from internal documents, but the document retriever returns by similarity chunks that are not relevant to the generated answer, so those ones should be removed, sometimes it works! I asked a question and the chunks are returned, sometimes I get an empty source list.

- [X] I added a very descriptive title to this issue.

- [X] I used the GitHub search to find a similar question and didn't find it.
### Example Code
This is a minor issue with metadata for pip. I opened a ticket against pip.
https://github.com/pypa/pip/issues/12476
But I was told that I should report the issue to this project.
[langchain_0.0.27.log](https://github.com/langchain-ai/langchain/files/13940154/langchain_0.0.27.log)
If there existed a langchain version which doesn't use future feature annotations, install it.
Otherwise, prompt the user that no suitable version.
### Description
I installed langchain 0.0.27 on python 3.6.5 on my Windows 10 successfully. But I run into an issue when I tried import the library.
from langchain.llms import Ollama
SyntaxError: future feature annotations is not defined
[PEP-563](https://www.python.org/dev/peps/pep-0563/#enabling-the-future-behavior-in-python-3-7)future annotations are introduced in Python 3.7. That means langchain 0.0.27 which depends on future feature annotations should NOT be installed on Python 3.6.5.
### System Info
pip 21.3.1
python 3.6.5/Windows 10

- [X] I used the GitHub search to find a similar question and didn't find it.
### Example Code
My code was fully working till i updated from 0.0.259 to 0.1.0 langchain
```
embeddings = OpenAIEmbeddings(openai_api_key=os.environ["OPENAI_API_KEY"],
model=os.environ["AZUREOPENAI_EMBEDDINGS_MODEL"],
deployment=os.environ["AZUREOPENAI_EMBEDDINGS_DEPLOYMENT"])
db = ElasticVectorSearch(
embedding=embeddings,
elasticsearch_url=url,
index_name=os.environ["AZUREOPENAI_INDEX_NAME"],
ssl_verify={"ca_certs": os.environ["APP_CERT_PATH"]}
)
docs = db.similarity_search(query=query, # new
k=10)
# Here is when it crashes
```
### Description
The code is crashing giving a weird error and It looks it is because of similarity_search doesnt work in the new version

- [X] I added a very descriptive title to this issue.
- [X] I searched the LangChain documentation with the integrated search.
- [X] I used the GitHub search to find a similar question and didn't find it.
### Example Code
```llm = LlamaCpp(model_path=model_loc, n_ctx=0, verbose=True, n_gpu_layers=-1)
chain = LLMChain(llm=llm, prompt=prompt)
result = chain(inputs={"context": context, "question": question})
answer = result["text"]
```
I do use the PromptTemplate, but this is not relevant to my issue.
### Description
I am using 2x A100 GPU. What I have noticed is that there is GPU degradation over time.
This is my spool up data:
```
ggml_init_cublas: GGML_CUDA_FORCE_MMQ: no
ggml_init_cublas: CUDA_USE_TENSOR_CORES: yes
ggml_init_cublas: found 2 CUDA devices:
Device 0: NVIDIA A100-PCIE-40GB, compute capability 8.0, VMM: no
Device 1: NVIDIA A100-PCIE-40GB, compute capability 8.0, VMM: no
```
In my code, the above is part of an API that takes in a request and then responds to it. I am making 5 calls to the API one after another, and collating the data for a final summarisation call.
I am not overly impressed with the speeds here in any event - so if anyone has any tips for improving, I don't think 17.25 tokens is very good for dual A100s.
```
llama_print_timings: eval time = 57.98 ms / 1 runs ( 57.98 ms per token, 17.25 tokens per second)
llama_print_timings: total time = 6722.12 ms
llama_print_timings: eval time = 4804.66 ms / 70 runs ( 68.64 ms per token, 14.57 tokens per second)
llama_print_timings: total time = 17722.48 ms
llama_print_timings: eval time = 5950.61 ms / 77 runs ( 77.28 ms per token, 12.94 tokens per second)
llama_print_timings: total time = 23459.58 ms
```
I would have expected the "overall" time to change but the actual tokens per second to remain somewhat consistent - but instead it just gets worse.
I also created a GPU monitor tool, and in that tool, the first call is utilising 25% and 20% for GPU 1 and 2 - but then it goes down to 20% and 17% and then 16% and 15%, and when making a LOT of calls, I have seen it as low as 9% on each GPU - at this point the response time is a minute plus.
Why am I writing a bug report here? Sounds like a you problem....because I ran it with Llama-cpp-python - without Langchain and this was not a problem, there was no degradation over time.
### System Info
Wrinkles....
I am using Window 10, inside a VMWare Virtual Machine. Python, Langchain, Llama-cpp-python is all up to date, as are the Nvidia drivers and CUDA toolkit (12.2).
As noted above - this only occurs when using langchain - not when doing the same workflow, without langchain.

- [X] I added a very descriptive title to this issue.
- [X] I searched the LangChain documentation with the integrated search.
- [X] I used the GitHub search to find a similar question and didn't find it.
### Example Code
Following code in https://github.com/langchain-ai/langchain/blob/master/libs/community/langchain_community/utilities/sql_database.py from line 386:
```
with self._engine.begin() as connection: # type: Connection
if self._schema is not None:
if self.dialect == "snowflake":
connection.exec_driver_sql(
"ALTER SESSION SET search_path = %s", (self._schema,)
)
elif self.dialect == "bigquery":
connection.exec_driver_sql("SET @@dataset_id=?", (self._schema,))
elif self.dialect == "mssql":
pass
elif self.dialect == "trino":
connection.exec_driver_sql("USE ?", (self._schema,))
elif self.dialect == "duckdb":
# Unclear which parameterized argument syntax duckdb supports.
# The docs for the duckdb client say they support multiple,
# but `duckdb_engine` seemed to struggle with all of them:
# https://github.com/Mause/duckdb_engine/issues/796
connection.exec_driver_sql(f"SET search_path TO {self._schema}")
elif self.dialect == "oracle":
connection.exec_driver_sql(
f"ALTER SESSION SET CURRENT_SCHEMA = {self._schema}"
)
elif self.dialect == "sqlany":
# If anybody using Sybase SQL anywhere database then it should not
# go to else condition. It should be same as mssql.
pass
else: # postgresql and other compatible dialects
connection.exec_driver_sql("SET search_path TO %s", (self._schema,))
```
### Description
Can we change the code of line 412:
```
else: # postgresql and other compatible dialects
connection.exec_driver_sql("SET search_path TO %s", (self._schema,))
```
to
```
elif self.dialect == "postgresql":
connection.exec_driver_sql("SET search_path TO %s", (self._schema,))
else:
pass # Do nothing
```
It is in my opinion simply wrong to assume that any other DB will work like PostgreSQL. And it's not possible to cut that statement in the dialect easily. If we need more `elif`, so be it.

In short, when you create a `ParentDocumentRetriever`, you can provide the arguments you would have provided to `index`. Then when you call `.add_documents`, `index` will be called with the provided arguments instead of directly persisting to the vector store.
This change also allows you to optionally provide a list of text splitters to `.add_documents` (being the same length as the list of documents), in case a single text splitter type for all docs that go through the receiver isn't appropriate. | {

A [visio file](https://fr.wikipedia.org/wiki/Microsoft_Visio) (with extension .vsdx) is associated with Microsoft Visio, a diagram creation software. It stores information about the structure, layout, and graphical elements of a diagram. This format facilitates the creation and sharing of visualizations in areas such as business, engineering, and computer science.
A Visio file can contain multiple pages. Some of them may serve as the background for others, and this can occur across multiple layers. This **loader** extracts the textual content from each page and its associated pages, enabling the extraction of all visible text from each page, similar to what an OCR algorithm would do.

The [Weaviate docs](https://python.langchain.com/docs/integrations/vectorstores/weaviate) just show examples of using `Weaviate.from_documents()` or `Weaviate.from_texts()`, but do not describe how to use an existing database with embedded documents already stored in the database.
Moreover, the descriptions of the `index_name` or `text_key` that are required when calling `Weaviate()` are not described anywhere in the [Weaviate docs](https://python.langchain.com/docs/integrations/vectorstores/weaviate), and `index_name` seems to be very misleading, given that it should be the name of the Weaviate *class*.
A naive attempt of:
```python
import os
import dotenv
import weaviate
from langchain_openai import ChatOpenAI
from langchain_core.prompts import ChatPromptTemplate
from langchain_core.output_parsers import StrOutputParser
from langchain_community.vectorstores import Weaviate
from langchain_core.runnables import RunnablePassthrough
dotenv.load_dotenv()
llm = ChatOpenAI(temperature=0, model_name="gpt-3.5-turbo")
client = weaviate.Client(
url="http://34.170.94.90",
auth_client_secret=weaviate.AuthApiKey(os.environ["WEAVIATE_API_KEY"])
)
db = Weaviate(client, 'my_class_name', 'text')
retriever = db.as_retriever()
chain = (
{"context": retriever, "question": RunnablePassthrough()}
| prompt
| llm
| output_parser
)
chain.invoke({"input" : "My particular query"})
```
Results in the error:
```
ValueError: Error during query: [{'locations': [{'column': 46, 'line': 1}], 'message': 'Syntax Error GraphQL request (1:46) Expected Name, found String "input"\n\n1: {Get{my_class_name(limit: 4 nearText: {concepts: [{"input": "My particular query"}]} ){text}}}\n ^\n', 'path': None}]
```
...which isn't too helpful on understanding the issue.
Note: I did actually use the correct class name instead of `my_class_name`.
### Idea or request for content:
It would be very helpful to include an example of using an existing Weaviate database, which included inspecting the DB schema to determine the values to use for `index_name` and `text_key`. | {

Implement `adelete` function from `VectorStore` in `Qdrant` to support other asynchronous flows such as async indexing (`aindex`) which requires `adelete` to be implemented. Since `Qdrant` can be passed an async qdrant client, this can be supported easily.

return await quick_suggestions_chain.arun(dialog=payload.dialog,
page_sku=payload.metadata.sku,
callbacks=group_manager) ```
When calling to chat route that is using websocket connection it stays in a pending status forever no matter what.
When calling QuickSuggestions it behave as expected.
I guess its something related to the websocket connection.
Any ideas?

- [X] I added a very descriptive title to this issue.
- [X] I searched the LangChain documentation with the integrated search.
- [X] I used the GitHub search to find a similar question and didn't find it.
### Example Code
None
### Description
* I am using the `AzureChatOpenAI` integration combined with the `SQLiteCache`.
* I noticed that the cache was working as intended within a single script invocation but not across multiple script invocations.
* I looked at what was being used as the cache key by inspecting what was being passed to the `SQLAlchemyCache.update()` method in the `llm_string` argument. Included is the `azure_ad_token` field used to initialise the `AzureChatOpenAI` class:
```
{"lc": 1, "type": "constructor", "id": ["langchain", "chat_models", "azure_openai", "AzureChatOpenAI"], "kwargs": {"azure_ad_token": "<removed>", "azure_endpoint": "<removed>", "openai_api_version": "2023-09-01-preview", "model": "gpt-4-0613", "temperature": 0.0, "max_tokens": 2000, "openai_api_type": "azure"}}---[('stop', **None)]**
```
* Our workflow involves rotating the `azure_ad_token` for every script invocation which is invalidating any cache matches.
The `azure_ad_token` field does not have any effect on the model output and is thus not needed and should not be included in the caching key.

- [X] I added a very descriptive title to this issue.
- [X] I searched the LangChain documentation with the integrated search.
- [X] I used the GitHub search to find a similar question and didn't find it.
### Example Code
The followiwng simple example will log the warning:
```python
from langchain_openai import AzureChatOpenAI
from langchain.schema import HumanMessage
chat_llm = AzureChatOpenAI()
chat_llm.invoke([HumanMessage(content='howdy!')])
```
### Description
I'm seeing a few warning logs saying that langchain-openai is using a deprecated method from pydantic: `dict`
```txt
.venv/Lib/site-packages/langchain_openai/chat_models/azure.py:199: PydanticDeprecatedSince20: The `dict` method is deprecated; use `model_dump` instead. Deprecated in Pydantic V2.0 to be removed in V3.0. See Pydantic V2 Migration Guide at https://errors.pydantic.dev/2.5/migration/
response = response.dict()

Support Cloudflare AI Gateway's endpoint `https://gateway.ai.cloudflare.com/v1/ACCOUNT_TAG/GATEWAY`
See https://developers.cloudflare.com/ai-gateway/providers/universal/
### Motivation
CF Workers AI (https://developers.cloudflare.com/workers-ai/get-started/rest-api/) is currently supported via the `CloudflareWorkersAI`,
Cloudflare AI Gateway is a different product with a different API (`CloudflareWorkersAI` with a custom `endpoint_url` won't work), and is currently unsupported.

In this PR, I am adding a `PolygonLastQuote` Tool, which can be used to get the latest price quote for a given ticker / stock.

Add the 'id' attribute to the Document class. Or add a method to get id.
### Motivation
Adding an 'id' attribute makes data manipulation easier.
When using the Weaviate database, I need to manually set additional parameters to query the 'id', and it's not convenient to use.
### Your contribution
At the moment, there isn't one. I'd like to discuss this issue first. | {

- [X] I added a very descriptive title to this issue.
- [X] I searched the LangChain documentation with the integrated search.
- [X] I used the GitHub search to find a similar question and didn't find it.
### Example Code
qa_chain = (
RunnablePassthrough.assign(context=( lambda x: format_docs(x["context"])))
| rag_prompt
| local_llm_api()
| StrOutputParser()
)
### Description
I am trying to call my local api endpoint in the qa chain.
The return type of the endpoint is a dict of list.
The error i am getting is :
Expected a Runnable, callable or dict.Instead got an unsupported type: <class 'list'>

Checklist:
- [x] Verify that each event has a good schema
- [x] Verify that each event does not do unintuitive type coercsions (inputs/outputs should not be automatically upgraded to dicts). This needs to be addressed `inputs=inputs if isinstance(inputs, dict) else {"input": inputs}`
- [ ] ~~Event `data` should not be dict if it doesn't need to be, but we don't want to get this wrong in case we need to dump extra info there!~~ `data` will always be a dict, with optional keys of `input` / `output` / `chunk` depending on event type. The reason is that `input` is not always available at event start
- [x] We need to make sure that the root run also generates event information
- [x] Propagate inputs when possible in Runnables
- [x] Tool inputs are encoded as json strings? Need to decode potentially
- [ ] Documentation
Changes downstream:
- `inputs` available in `logs` path of astream_log -- this could lead to breaking changes in langserve if langserve fails to serialize any of the messages. (If there are messages there that are well known but haven't been registered as well known messages).
- the `output` and `final_output` has been made more consistent, one could argue that this is a bug fix, but if it's widely used could cause user's code to break.
Potential Future Changes:
* StreamingEvent add `parent_id` key which has the id of the parent runnable
* [Internal] Update the BaseTracer or create a new version of it that stops doing type
coercions (needs to be backwards compatibility to avoid breaking existing functionality that relies on dictinoaries)

- [X] I used the GitHub search to find a similar question and didn't find it.
### Example Code
from langchain_community.embeddings import HuggingFaceHubEmbeddings
url = "https://svvwc5yh51gt1pp3.us-east-1.aws.endpoints.huggingface.cloud"
text = "You do not need a weatherman to know which way the wind blows"
token = "<my_token>"
embeddings = HuggingFaceHubEmbeddings(
model = url,
huggingfacehub_api_token=token
)
qembed = embeddings.embed_query(text)
### Description
The code above should call my HuggingFace inference endpoint and generate an embedding. Instead, it throws:
Traceback (most recent call last):
File "/Users/jraby/python/hfhub/callhub2.py", line 29, in <module>
qembed = embeddings.embed_query(text)
File "/opt/homebrew/lib/python3.10/site-packages/langchain_community/embeddings/huggingface_hub.py", line 109, in embed_query
response = self.embed_documents([text])[0]
KeyError: 0
The "[0]" at the end of line 109 is incorrect. self.embed_documents returns JSON, -not a list. The first node in the JSON is 'embeddings', and it contains the list of embedding arrays.
I believe that this line:
response = self.embed_documents([text])[0]
Should be replaced with this:
response = self.embed_documents([text])['embeddings'][0]
This resolves the problem for me.

- **Description:** Added new Runnables for integration NVIDIA Riva into LCEL chains for Automatic Speech Recognition (ASR) and Text To Speech (TTS).
- **Issue:** N/A
- **Dependencies:** To use these runnables, the NVIDIA Riva client libraries are required. It they are not installed, an error will be raised instructing how to install them. The Runnables can be safely imported without the riva client libraries.
- **Twitter handle:** N/A
All of the Riva Runnables are inside a single folder in the Utilities module. In this folder are four files:
- common.py - Contains all code that is common to both TTS and ASR
- stream.py - Contains a class representing an audio stream that allows the end user to put data into the stream like a queue.
- asr.py - Contains the RivaASR runnable
- tts.py - Contains the RivaTTS runnable
The following Python function is an example of creating a chain that makes use of both of these Runnables:
```python
def create(
config: Configuration,
audio_encoding: RivaAudioEncoding,
sample_rate: int,
audio_channels: int = 1,
) -> Runnable[ASRInputType, TTSOutputType]:
"""Create a new instance of the chain."""
_LOGGER.info("Instantiating the chain.")
# create the riva asr client
riva_asr = RivaASR(
url=str(config.riva_asr.service.url),
ssl_cert=config.riva_asr.service.ssl_cert,
encoding=audio_encoding,
audio_channel_count=audio_channels,
sample_rate_hertz=sample_rate,
profanity_filter=config.riva_asr.profanity_filter,
enable_automatic_punctuation=config.riva_asr.enable_automatic_punctuation,
language_code=config.riva_asr.language_code,
)
# create the prompt template
prompt = PromptTemplate.from_template("{user_input}")
# model = ChatOpenAI()
model = ChatNVIDIA(model="mixtral_8x7b") # type: ignore
# create the riva tts client
riva_tts = RivaTTS(
url=str(config.riva_asr.service.url),
ssl_cert=config.riva_asr.service.ssl_cert,
output_directory=config.riva_tts.output_directory,
language_code=config.riva_tts.language_code,
voice_name=config.riva_tts.voice_name,
)
# construct and return the chain
return {"user_input": riva_asr} | prompt | model | riva_tts # type: ignore
```
The following code is an example of creating a new audio stream for Riva:
```python
input_stream = AudioStream(maxsize=1000)
# Send bytes into the stream
for chunk in audio_chunks:
await input_stream.aput(chunk)
input_stream.close()
```
The following code is an example of how to execute the chain with RivaASR and RivaTTS
```python
output_stream = asyncio.Queue()
while not input_stream.complete:
async for chunk in chain.astream(input_stream):
output_stream.put(chunk)
```
Everything should be async safe and thread safe. Audio data can be put into the input stream while the chain is running without interruptions. | {

I wasn't able to follow the [quick start guide](https://python.langchain.com/docs/get_started/quickstart) because of a dependency issue. Everything was going well until I tried to install Faiss.
### Idea or request for content:
My experience trying to follow langchain quick start guide:
# The background
I'm a experienced developer, but I'm new to python and notebooks. I've been studying langchain for a while now, and I'm trying to get started with the quick start guide. I'm using a mac (Apple M2) and I'm trying to follow the guide using the jupyter notebook on VS code.
# The beginning
Starting with the first step, I'm trying to install the dependencies. I'm using the following command:
```
pyenv install 3.12.0 # install python version
pyenv local 3.12.0 # set python version
python -m venv venv # create virtual environment
source ./venv/bin/activate # activate virtual environment
pip3 install -r requirements.txt # install dependencies
```
Where the requirements.txt file contains the following:
```
jupyterlab
langchain==0.1.0
langchain-openai
beautifulsoup4
```
So far so good. Actually, I was so surprised and happy that everything worked so well, that I kind of knew something was going to go wrong. Anyways... I was able to install everything without any problems, and with that run the notebook from beginning to the beginning of "Retrieval Chain".
# The problem
When I try to [install Faiss](https://python.langchain.com/docs/get_started/quickstart#retrieval-chain):
```
pip install faiss-cpu
```
I get the following a [error](https://github.com/facebookresearch/faiss/issues/2868#issuecomment-1889724871) (which apparently is not only me who is getting it). Not only that, but it seems Faiss is not [supposed to be installed using `pip`](https://github.com/facebookresearch/faiss/issues/2991#issuecomment-1667640023).
After trying `conda` and a bunch of other things, none of which worked, I decided to try a different local vector db.
# The kafkaesque journey
So the next step was trying to install any local vector db that could work and hopefully be compatible with the quick start guide.
**Chroma**:
Added `chromadb` to the requirements.txt file and tried to install it. Got the following error:
```bash
...
ERROR: Cannot install -r requirements.txt (line 1), -r requirements.txt (line 3) and -r requirements.txt (line 5) because these package versions have conflicting dependencies.
The conflict is caused by:

langchain 0.1.0 depends on numpy<2 and >=1
langchain-openai 0.0.2 depends on numpy<2 and >=1

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict
```
As far as I can tell, and after reading a few posts, it seems that there is not much I can do about this. So I tried the next one.
**Milvus**:
Added `pymilvus` to the requirements.txt file and tried to install it. Got the following error:
```

During handling of the above exception, another exception occurred:

I tried a few stackoverflow solutions, but none of them worked. Blocked again.
# The solution
I haven't found a solution yet, but I would like to share my experience so far. I will keep trying to find a solution, and if I do, I will update this post. However, I would like to enfatize how painful has been trying to start using langchain for someone who is new to python and the hole ecosystem. I know it's a new field and in a way I felt like configuring the video driver on my first linux distro in the 90s. Sharing this experience is not meant to be a rant, but to help the community to improve the experience for new users. | {

- [X] I added a very descriptive title to this issue.
- [X] I searched the LangChain documentation with the integrated search.
- [X] I used the GitHub search to find a similar question and didn't find it.
### Example Code
multiquery_llm_retriever = MultiQueryRetriever.from_llm(
retriever = vectordb.as_retriever(),
llm=llm,
include_original = top_k_params["mq_include_original"]
)
docs = multiquery_llm_retriever.get_relevant_documents(query=user_input)
Response of the underlying generate_queries function:
{'question': 'The actual question', 'text': LineList(lines=['Alternative Question 1: First generated question?', '', 'Alternative Question 2: Second generated question?', '', 'Alternative Question 3: Third generated question?'])}
Notice that in between are empty strings: ''
They later cause an error in similarity search since empty strings cannot be embedded. Consequently, the retrieve_documents function fails.
### Description
I am trying to use the MultiQueryRetriever. However, the generate queries function returns a list that contains empty strings in between the 3 (as in the default prompt) generated answers.
This will later cause the retrieve_documents to fail since the similarity search throws an exception.

The mode argument can only be a string (also see the assertion in the `__init__`: `assert self.mode in ["single", "page", "object", "markdown"]`, so the check `elif self.mode == ["page"]:` always fails.
As a result, effectively the "object" mode is used when selecting the "page" mode, which may lead to errors.
The docstring of the `AzureAIDocumentIntelligenceLoader` also ommitted the `mode` parameter alltogether, so I added it.
**Issue**: I could not find a related issue (this class is only 3 weeks old anyways)
**Dependencies**: this PR does not introduce or affect dependencies.
The current demo notebook and examples are not affected because they all use the default markdown mode.

- [X] I added a very descriptive title to this issue.
- [X] I searched the LangChain documentation with the integrated search.
- [X] I used the GitHub search to find a similar question and didn't find it.
### Example Code
```python
prompt_template = ("Human: Say hello to the user using the given username."
"Username: {username}")
chain = LLMChain(
llm=llm,
prompt=PromptTemplate(template=prompt_template, input_variables=[]),
verbose=True,
)
def execute(args:dict):
with callbacks.collect_runs() as cb:
try:
output = chain.invoke(args)
print(f"output: {output}")
finally:
print(f"traced_runs: {cb.traced_runs}")
# executes successfully
execute({"username": "John"})
# failed with validation error, but traced runs is empty, while it should have one run with exception details
execute({"user_name": "John"})
``
### Description
Callback manager doesn't get invoked if there's an input or output validation error.
For logging purposes the callback manager should be invoked and any chain related error, even if it's a validation error.
The related logic exists in file `langchain/chains/base.py` in `acall` and `__call__` functions, as the `callback_manager` & `run_manager` gets initialized after validating input. To fix this, `run_manager` should be initialized first, then wrap preparing input, output and executing in try/except and update the `run_manager` accordingly

### Example Code
I want to create an OpenAI assistant using an existing ID, but I'm encountering an error.
1. assistant = OpenAIAssistantRunnable(assistant_id='assistant_id', as_agent=True)
`openai.OpenAIError: The api_key client option must be set either by passing api_key to the client or by setting the OPENAI_API_KEY environment variable`
2. assistant = OpenAIAssistantRunnable(assistant_id='assistant_id', as_agent=True, client=openai.OpenAI(api_key=self.model.openai_api_key))
`pydantic.v1.errors.ConfigError: field "client" not yet prepared, so the type is still a ForwardRef. You might need to call OpenAIAssistantRunnable.update_forward_refs()`
In both cases, an error is encountered. The only successful scenario is when the openai_api_key is set in the environment, but my requirement is for the user to provide it. Has anyone else faced a similar issue? Any assistance would be appreciated.
### Description
OpenAIAssistantRunnable raise exception when pass client. There should be a way to pass the key from outside

<div type='discussions-op-text'>
<sup>Originally posted by **arthurbrenno** January 11, 2024</sup>
I'm trying to make a **generalized method** that **works with any vector database**, so I can **change the implementation** later. The main focus is simply ingesting documents inside a vectorstore.
My main issue always has been **_data persistency_** and the _flexibility_ to change the vector database implementation, because I like to explore different alternatives and there are many of them. That's why I'm (trying) to make a method like this.
Here's a snippet of my implementation:
```py
from langchain_community.document_loaders.base import BaseLoader
from langchain_core.documents.base import Document
from langchain_core.embeddings import Embeddings
from langchain.vectorstores import VectorStore
from conversai.core.services import BaseService
from langchain.text_splitter import TextSplitter
from typing import List, Type, Dict
from typing import Any
class IngestionService(BaseService):
"""Class that handles the ingestion of documents inside a vector store."""
async def execute(url: str,
collection: str,
loader_class: Type[BaseLoader],
splitter: TextSplitter,
embeddings: Embeddings,
vector_store_cls: Type[VectorStore],
**vector_store_kwargs) -> Dict[str, Any]:
"""Ingests a document inside the desired vector store.
Args:
url (str): Url of the document to ingest.
collection (str): Collection of the vector store to ingest the document.
loader (BaseLoader): The loader of the document.
splitter (TextSplitter): The splitter of the document.
embeddings (Embeddings): The embedding model to apply on the splitted documents.
vector_store (VectorStore): The vector store to store the document.
Returns:
bool: True on success, False on failure.
"""
# Instantiating the loader
loader: BaseLoader = loader_class(url)
# Loading and splitting the document
documents: List[Document] = loader.load_and_split(text_splitter=splitter)
# Instantiating the vector store (assuming every implementation should support collection_name and embedding_func.)
vector_store: VectorStore = vector_store_cls(collection_name=collection,
embedding_func=embeddings,
**vector_store_kwargs)
# ids of the created texts
texts_ids: List[str] = await vector_store.aadd_documents(documents)
return {"success": True, "ingested_texts_ids": texts_ids}
```
The problem is that every vector database seems to have a different way of persisting itself (as I understood). For an example:
Chroma:
```py
db = Chroma(persist_directory=...)
```
(or using their separate client whitin Docker
```py
db = Chroma(client=client)
```
FAISS:
```py
# FAISS has
db.save_local("faiss_index")
```
I need to ingest documents **at runtime.** This is important. I also need to group them inside `collections` for better searching later and group similar documents. Creating collections is one of my future implementations.
My current vector store implementation is `Milvus`. And I think I'm generalising too much when I assume every vector db will have a "collection_name" and "embedding_func", like written in:
```py
vector_store: VectorStore = vector_store_cls(collection_name=collection,
embedding_func=embeddings,
**vector_store_kwargs)
```
Any support on making my method better is appreciated. I'm also reading the documentation and trying to solve this for myself, but I think community help would also be a great startpoint. One of my suggestions (I've seen some people talking about this) is making the documentation more clear about data persistency. The examples only show short-term usage of the vectorstores, which is not the case in many production enviroments</div> | {

Remove section on how to install Action Server and direct the users t o the instructions on Robocorp repository.
**Reason:**
Robocorp Action Server has moved from a pip installation to a standalone cli application and is due for changes. Because of that, leaving only LangChain integration relevant part in the documentation. | {

In this update, I addressed the missing implementation for atransform_document, which is the asynchronous counterpart of transform_document in Doctran.
### Usage Example:
```py
# Instantiate DoctranPropertyExtractor with specified properties
property_extractor = DoctranPropertyExtractor(properties=properties)
# Asynchronously extract properties from a list of documents
extracted_document = await property_extractor.atransform_documents(
documents, properties=properties
)
# Display metadata of the first extracted document
print(json.dumps(extracted_document[0].metadata, indent=2))
```
## Issue
- Pull request #14525 has caused a break in the aforementioned code. Instead of removing an asynchronous implementation of a function, consider implementing a synchronous version alongside it. | {

- [X] I added a very descriptive title to this issue.
- [X] I searched the LangChain documentation with the integrated search.
- [X] I used the GitHub search to find a similar question and didn't find it.
### Example Code
In langchain_community/vectorstores/jaguar.py line 196:
values_comma = "'" + "','".join(vvec) + "'"
If any element in vvec is not string, runtime error is thrown:
TypeError: sequence item 0: expected str instance, int found
The vvec is a list of values in metadata dictionary.
### Description
* Some document loaders, for instance, PyPDFDirectoryLoader, add an integer page number to the metadata. In such cases, the list of values contain integer elements. The statement "','".join(vvec) will report an error.

The tool I'm talking about is:
from langchain.tools import ShellTool
As Shell tool is very versatile, while integrating it into applications as openai functions, developers have no clue about what command is being executed using the ShellTool. All one can see is:
Which shouldn't be the case right ? Developers need to know what command is going to be executed by the ShellTool, and whether its the right command to execute, or you just prompt better for the LLM to generate a new command and let that execute.
Summarising my feature request:
1. There's no visibility about what command was executed.
2. There's no mechanism to prevent a command to be executed using ShellTool, like a y/n human input which can be accepted from user to proceed with executing the command.
I would like to implement this in a PR if the project maintainer feels this feature adds value.
### Motivation
I was using ShellTool as a OpenAI Function in Autogen, which is a multi-agent conversation framework. Where in one of my AI Agent is a programmer, and it has access to the ShellTool. When its executing any command using ShellTool, we have no clue about what command is being executed, and are thrown to mercy of the LLM that the generated command is what we need.
### Your contribution
I have raised a [PR](https://github.com/langchain-ai/langchain/pull/15932), would like you to review and provide feedback on it. Or if there's some other way around to implement the feature I'm proposing, please let me know. | {

<sup>Originally posted by **BalajiPolisetty2207** January 11, 2024</sup>
i am using this langchain to query my postgres sql with natural language.
with sql server i am successful in asking and getting answers .
I am using azure open ai key and endpoint and gpt 4 model and deployment .
Can some one help what is missing here to query postgressql and how i can set the schema before querying.
Below is the code

When there are multiple GPUs available, the Ollama API provides the main_gpu option to specify which GPU to use as the main one. Please modify Langchain's ChatOllama to also include this feature.
### Motivation
When running multiple tasks simultaneously on a server, it is necessary to designate specific processes for Ollama.

With langchain version == 0.1.0
This stop param of the Class VLLM does not work.
For instance, this code has no effect regarding stop word.
```
model = VLLM(
stop=["stop_word"],
model=model_name,
trust_remote_code=True, # mandatory for hf models
max_new_tokens=512,
top_k=10,
top_p=0.95,
temperature=0.2,
vllm_kwargs=vllm_kwargs,
)
```
But this code works:
```
prompt = PromptTemplate(
template=template, input_variables=["system_message", "question"]
)
llm_chain = LLMChain(prompt=prompt, llm=model)
llm_chain.run(
{"system_message": system_message, "question": question, "stop":["stop_word"]}
)
```
### Idea or request for content:
Clear the documentation or it is a bug. | {

llm = ChatOpenAI(temperature=0)
vectorstore = Pinecone.from_existing_index(index_name="test", embedding=get_embedding_function())
# print("Load existing vector store")\
retriever = SelfQueryRetriever.from_llm(
llm,
vectorstore,
"Information about when the document was created and where it was grabbed from.",
metadata_field_info,
)
```
```python
question = "Give the minimum opening deposits for each accounts for the rate sheets in January"
retriever.get_relevant_documents(question)
```
### Description
When I ask to fetch relevant documents with the following query:
- "Give the minimum opening deposits for each accounts for the rate sheets in January"
There is no problem. However, if I make this query a little more robust...
- "Give the minimum opening deposits for each accounts for the rate sheets in January 2023"
I get a CNAME "and" error. This happens in both Pinecone and ChromaDB. Something is wrong with how the query translator is operating or I am missing some crucial step. We should be able to use multiple metadata flags at once.

Fixes OutputParserException thrown by the output_parser when 'query' is 'Null'.
Replace this entire comment with:
- **Description:** Current implentation of output_parser throws OutputParserException if the response from the LLM contains `query: null`. This unfortunately happens for my use case. And since there is no way to modify the prompt used in SelfQueryRetriever, then we have to fix it here, so it doesn't crash.
- **Issue:** https://github.com/langchain-ai/langchain/issues/15914
Didn't run tests. `make test` is not working. There is no `test` rule in the `Makefile`. | {

### Example Code
See description.
### Description
I am using SelfQueryRetriever. For a response JSON that contains null query, for example:
```
json
{
"query": null,
"filter": ...
}
```
The output parser throws OutputParserException at [line 51](https://github.com/langchain-ai/langchain/blob/master/libs/langchain/langchain/chains/query_constructor/base.py#L51).
OutputParserException('Parsing text\n```json\n{\n "query": null,\n "filter": "eq(\\"kategorie\\", \\"Pravo\\")"\n}\n```\n raised following error:\nobject of type \'NoneType\' has no len()')Traceback (most recent call last):
