# Converted LLaMA from QWEN2-7B-Instruct

## Descritpion
This is a converted model from [Qwen2-7B-Instruct](https://huggingface.co/Qwen/Qwen2-7B-Instruct) to __LLaMA__ format. This conversion allows you to use Qwen2-7B-Instruct as if it were a LLaMA model, which is convenient for some *inference use cases*. The __precision__ is __excatly the same__ as the original model. 

## Usage
You can load the model using the `LlamaForCausalLM` class as shown below:
```python
from transformers import AutoTokenizer, LlamaForCausalLM

prompt = "Give me a short introduction to large language model."
messages = [
    {"role": "system", "content": "You are a helpful assistant."},
    {"role": "user", "content": prompt}
]
# we still use the original tokenizer from Qwen2-7B-Instruct
tokenizer = AutoTokenizer.from_pretrained("Qwen/Qwen2-7B-Instruct")
text = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True
)
model_inputs = tokenizer([text],return_tensors="pt").cuda()

# Converted LlaMA model
llama_model = LlamaForCausalLM.from_pretrained(
    "silence09/Qwen2-7B-Instruct-Converted-Llama",
    torch_dtype='auto').cuda()
llama_generated_ids = llama_model.generate(model_inputs.input_ids, max_new_tokens=32, do_sample=False)
llama_generated_ids = [
    output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, llama_generated_ids)
]
llama_response = tokenizer.batch_decode(llama_generated_ids, skip_special_tokens=True)[0]
print(llama_response)
```

## Precision Guarantee
To comare result with the original model, you can use this [code](https://github.com/silencelamb/naked_llama/blob/main/hf_example/hf_qwen2_7b.py)

## More Info
It was converted using the python script available at [this repository](https://github.com/silencelamb/naked_llama/blob/main/hf_example/convert_qwen_to_llama_hf.py)
