+This is the Mistral version of [Qwen1.5-0.5B-Chat](https://huggingface.co/Qwen/Qwen1.5-0.5B-Chat) model by Alibaba Cloud.
+The original codebase can be found at: (https://github.com/hiyouga/LLaMA-Factory/blob/main/tests/llamafy_qwen.py).
+I have made modifications to make it compatible with qwen1.5.
+This model is converted with https://github.com/Minami-su/character_AI_open/blob/main/mistral_qwen2.py
+
+## special
+
+1.Before using this model, you need to modify modeling_mistral.py in transformers library
+
+2.vim /root/anaconda3/envs/train/lib/python3.9/site-packages/transformers/models/mistral/modeling_mistral.py
+
+3.find MistralAttention,
+
+4.modify q,k,v,o bias=False ----->, bias=config.attention_bias

+
+## Differences between qwen2 mistral and qwen2 llamafy
+
+Compared to qwen2 llamafy,qwen2 mistral can use sliding window attention,qwen2 mistral is faster than qwen2 llamafy, and the context length is better
+
+
+Usage:
+
+```python
+
+from transformers import AutoModelForCausalLM, AutoTokenizer, TextStreamer
+tokenizer = AutoTokenizer.from_pretrained("Minami-su/Qwen1.5-0.5B-Chat_mistral")
+model = AutoModelForCausalLM.from_pretrained("Minami-su/Qwen1.5-0.5B-Chat_mistral", torch_dtype="auto", device_map="auto")
+streamer = TextStreamer(tokenizer, skip_prompt=True, skip_special_tokens=True)
+
+messages = [
+    {"role": "user", "content": "Who are you?"}
+]
+inputs = tokenizer.apply_chat_template(messages, tokenize=True, add_generation_prompt=True, return_tensors="pt")
+inputs = inputs.to("cuda")
+generate_ids = model.generate(inputs,max_length=2048, streamer=streamer)
+
+```
