# emissions-extraction-lora
This is a LoRA for the [mistralai/Mistral-7B-Instruct-v0.2](https://huggingface.co/mistralai/Mistral-7B-Instruct-v0.2) model finetuned on the [nopperl/sustainability-report-emissions-instruction-style](https://huggingface.co/datasets/nopperl/sustainability-report-emissions-instruction-style) dataset.
## Model description
Given text extracted from pages of a sustainability report, this model extracts the scope 1, 2 and 3 emissions in JSON format. The JSON object also contains the pages containing this information. For example, the [2022 sustainability report by the Bristol-Myers Squibb Company](https://www.bms.com/assets/bms/us/en-us/pdf/bmy-2022-esg-report.pdf) leads to the following output: `{"scope_1":202290,"scope_2":161907,"scope_3":1696100,"sources":[88,89]}`.
Reaches an emission value extraction accuracy of 65\% (up from 46\% of the base model) and a source citation accuracy of 77\% (base model: 52\%) on the [corporate-emission-reports](https://huggingface.co/datasets/nopperl/corporate-emission-reports) dataset. For more information, refer to the [GitHub repo](https://github.com/nopperl/corporate_emission_reports).
## Intended uses & limitations
The model is intended to be used together with the [mistralai/Mistral-7B-Instruct-v0.2](https://huggingface.co/mistralai/Mistral-7B-Instruct-v0.2) model using the `inference.py` script from the [accompanying python package](https://github.com/nopperl/corporate_emission_reports). The script ensures that the prompt string and token ids exactly match the ones used for training.
### Example usage
#### CLI
Using [transformers](https://github.com/huggingface/transformers) as inference engine:
python -m corporate_emissions_reports.inference --model_path mistralai/Mistral-7B-Instruct-v0.2 --lora nopperl/emissions-extraction-lora --model_context_size 32768 --engine hf https://www.bms.com/assets/bms/us/en-us/pdf/bmy-2022-esg-report.pdf
Compare to base model without LoRA:
python -m corporate_emissions_reports.inference --model_path mistralai/Mistral-7B-Instruct-v0.2 --model_context_size 32768 --engine hf https://www.bms.com/assets/bms/us/en-us/pdf/bmy-2022-esg-report.pdf
Alternatively, it is possible to use [llama.cpp](https://github.com/ggerganov/llama.cpp) as inference engine. In this case, follow the installation instructions of the [package readme](https://github.com/nopperl/corporate_emission_reports/blob/main/README.md). In particular, the model needs to be downloaded beforehand. Then:
python -m corporate_emissions_reports.inference --model mistral --lora ./emissions-extraction-lora/ggml-adapter-model.bin https://www.bms.com/assets/bms/us/en-us/pdf/bmy-2022-esg-report.pdf
Compare to base model without LoRA:
python -m corporate_emissions_reports.inference --model mistral https://www.bms.com/assets/bms/us/en-us/pdf/bmy-2022-esg-report.pdf
#### Programmatically
The package also provides a function for inference from python code:
from corporate_emission_reports.inference import extract_emissions
document_path = "https://www.bms.com/assets/bms/us/en-us/pdf/bmy-2022-esg-report.pdf"
model_kwargs = {} # Optional arguments with are passed to the HF model
emissions = extract_emissions(document_path, "mistralai/Mistral-7B-Instruct-v0.2", lora="nopperl/emissions-extraction-lora", engine="hf", **model_kwargs)
It's also possible to use it directly with [transformers](https://github.com/huggingface/transformers):
```
from corporate_emission_reports.inference import construct_prompt
from peft import AutoPeftModelForCausalLM
from transformers import AutoTokenizer
document_path = "https://www.bms.com/assets/bms/us/en-us/pdf/bmy-2022-esg-report.pdf"
lora_path = "nopperl/emissions-extraction-lora"
tokenizer = AutoTokenizer.from_pretrained(lora_path)
prompt_text = construct_prompt(document_path, tokenizer)
model = AutoPeftModelForCausalLM.from_pretrained(lora_path)
prompt_tokenized = tokenizer.encode(prompt_text, return_tensors="pt").to(model.device)
outputs = model.generate(prompt_tokenized, max_new_tokens=120)
output = outputs[0][prompt_tokenized.shape[1]:]
```
Additionally, it is possible to enforce valid JSON output and convert it into a Pydantic object using [lm-format-enforcer](https://github.com/noamgat/lm-format-enforcer):
```
from corporate_emission_reports.pydantic_types import Emissions
from lmformatenforcer import JsonSchemaParser
from lmformatenforcer.integrations.transformers import build_transformers_prefix_allowed_tokens_fn
...
parser = JsonSchemaParser(Emissions.model_json_schema())
prefix_function = build_transformers_prefix_allowed_tokens_fn(tokenizer, parser)
outputs = model.generate(prompt_tokenized, max_new_tokens=120, prefix_allowed_tokens_fn=prefix_function)
output = outputs[0][prompt_tokenized.shape[1]:]
if tokenizer.eos_token:
output = output[:-1]
output = tokenizer.decode(output)
return Emissions.model_validate_json(output, strict=True)
```
## Training and evaluation data
Finetuned on the [sustainability-report-emissions-instruction-style](https://huggingface.co/datasets/nopperl/sustainability-report-emissions-instruction-style) dataset and evaluated on the [corporate-emission-reports](https://huggingface.co/datasets/nopperl/corporate-emission-reports).
## Training procedure
Trained on two A40 GPUs with ZeRO Stage 3 and FlashAttention 2. ZeRO-3 and FlashAttention 2 are necessary to just barely fit the sequence length of 32768 (without them, the max sequence length was 6144). The bloat16 datatype (and no quantization) was used. One epoch took roughly 3 hours.
### Training hyperparameters
The following hyperparameters were used during training:
- learning_rate: 5e-06
