# Converted Qwen2 from InternLM3-8B-Instruct

## Descritpion
This is a converted model from [InternLM3-8B-Instruct](https://huggingface.co/internlm/internlm3-8b-instruct) to __Qwen2__ format. This conversion allows you to use InternLM3-8B-Instruct as if it were a Qwen2 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 `Qwen2ForCausalLM` class as shown below:
```python
from transformers import AutoModelForCausalLM, AutoTokenizer, Qwen2ForCausalLM

device = "cuda" # the device to load the model onto, cpu or cuda
attn_impl = 'eager' # the attention implementation to use

prompt = "大模型和人工智能经历了两年的快速发展，请你以此主题对人工智能的从业者写一段新年寄语"

system_prompt = """You are an AI assistant whose name is InternLM (书生·浦语).
- InternLM (书生·浦语) is a conversational language model that is developed by Shanghai AI Laboratory (上海人工智能实验室). It is designed to be helpful, honest, and harmless.
- InternLM (书生·浦语) can understand and communicate fluently in the language chosen by the user such as English and 中文."""
messages = [
    {"role": "system", "content": system_prompt},
    {"role": "user", "content": prompt},
 ]

tokenizer = AutoTokenizer.from_pretrained("silence09/InternLM3-8B-Instruct-Converted-Qwen2", trust_remote_code=True)
text = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True
)
model_inputs = tokenizer([text], return_tensors="pt").to(device)
print(prompt)
qwen2_model = Qwen2ForCausalLM.from_pretrained(
    "silence09/InternLM3-8B-Instruct-Converted-Qwen2",
    torch_dtype='auto',
    attn_implementation=attn_impl).to(device)
qwen2_generated_ids = qwen2_model.generate(model_inputs.input_ids, max_new_tokens=100, do_sample=False)
qwen2_generated_ids = [
    output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, qwen2_generated_ids)
]
qwen2_response = tokenizer.batch_decode(qwen2_generated_ids, skip_special_tokens=True)[0]
print(qwen2_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_internlm3_8b_qwen2_compare.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_internlm3_to_qwen_hf.py)
