|
## Use |
|
|
|
### Setup |
|
|
|
First, we have to install all the libraries listed in `requirements.txt` in [GitHub](https://github.com/OpenLemur/lemur-v1): |
|
|
|
```bash |
|
pip install -r requirements.txt |
|
``` |
|
|
|
### Generation |
|
|
|
```python |
|
from transformers import AutoTokenizer, AutoModelForCausalLM |
|
|
|
tokenizer = AutoTokenizer.from_pretrained("OpenLemur/lemur-70b-chat-v1") |
|
model = AutoModelForCausalLM.from_pretrained("OpenLemur/lemur-70b-chat-v1", device_map="auto", load_in_8bit=True) |
|
|
|
# Text Generation Example |
|
prompt = """<|im_start|>system |
|
You are a helpful, respectful, and honest assistant. |
|
<|im_end|> |
|
<|im_start|>user |
|
What's a lemur's favorite fruit?<|im_end|> |
|
<|im_start|>assistant |
|
""" |
|
input = tokenizer(prompt, return_tensors="pt") |
|
output = model.generate(**input, max_length=50, num_return_sequences=1) |
|
generated_text = tokenizer.decode(output[0], skip_special_tokens=True) |
|
print(generated_text) |
|
|
|
# Code Generation Example |
|
prompt = """<|im_start|>system |
|
Below is an instruction that describes a task. Write a response that appropriately completes the request. |
|
<|im_end|> |
|
<|im_start|>user |
|
Write a Python function to merge two sorted lists into one sorted list without using any built-in sort functions.<|im_end|> |
|
<|im_start|>assistant |
|
""" |
|
input = tokenizer(prompt, return_tensors="pt") |
|
output = model.generate(**input, max_length=200, num_return_sequences=1) |
|
generated_code = tokenizer.decode(output[0], skip_special_tokens=True) |
|
print(generated_code) |
|
``` |
