## How to Get Started with the Model
|
38 |
+
|
39 |
+
Use the code below to get started with the model. Note that you need to install `sentencepiece` and `accelerate` libraries to run this code.
|
40 |
+
|
41 |
+
```python
|
42 |
+
from transformers import LlamaTokenizer, LlamaForCausalLM
|
43 |
+
import torch
|
44 |
+
|
45 |
+
device = "cuda" if torch.cuda.is_available() else "cpu"
|
46 |
+
model = LlamaForCausalLM.from_pretrained(
|
47 |
+
"universitytehran/PersianMind-v1.0",
|
48 |
+
torch_dtype=torch.bfloat16,
|
49 |
+
low_cpu_mem_usage=True,
|
50 |
+
device_map={"": device},
|
51 |
+
)
|
52 |
+
tokenizer = LlamaTokenizer.from_pretrained(
|
53 |
+
"universitytehran/PersianMind-v1.0",
|
54 |
+
)
|
55 |
+
|
56 |
+
TEMPLATE = "{context}\nYou: {prompt}\nPersianMind: "
|
57 |
+
CONTEXT = "This is a conversation with PersianMind. It is an artificial intelligence model designed by a team of " \
|
58 |
+
"NLP experts at the University of Tehran to help you with various tasks such as answering questions, " \
|
59 |
+
"providing recommendations, and helping with decision making. You can ask it anything you want and " \
|
60 |
+
"it will do its best to give you accurate and relevant information."
|
61 |
+
PROMPT = "در مورد هوش مصنوعی توضیح بده."
|
62 |
+
|
63 |
+
model_input = TEMPLATE.format(context=CONTEXT, prompt=PROMPT)
|
64 |
+
input_tokens = tokenizer(model_input, return_tensors="pt")
|
65 |
+
input_tokens = input_tokens.to(device)
|
66 |
+
generate_ids = model.generate(**input_tokens, max_new_tokens=512, do_sample=False, repetition_penalty=1.1)
|
67 |
+
model_output = tokenizer.batch_decode(generate_ids, skip_special_tokens=True, clean_up_tokenization_spaces=False)[0]
|
68 |
+
model_output = model_output.replace(model_input, "")
|
69 |
+
|
70 |
+
print(model_output)
|
71 |
+
```
