Qwen2-0.5B-Instruct-llamafy

This is the LLaMAfied version of Qwen2-0.5B-Instruct 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 qwen2. This model is converted with https://github.com/Minami-su/character_AI_open/tree/main/Qwen2_llamafy_Mistralfy

Usage:

from transformers import AutoModelForCausalLM, AutoTokenizer, TextStreamer
tokenizer = AutoTokenizer.from_pretrained("Minami-su/Qwen2-0.5B-Instruct-llamafy")
model = AutoModelForCausalLM.from_pretrained("Minami-su/Qwen2-0.5B-Instruct-llamafy", 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)
