InternLM2-Chat-1.8B 模型测试

在interStudio进行InternLM2-Chat-1.8B模型访问，进入开发机后

1. 配置基础环境
   新建conda环境并且进入
   conda create -n demo python3.10 -y
   conda activate demo
   下载pytorch等相关包
   conda install pytorch2.0.1 torchvision0.15.2 torchaudio2.0.2 pytorch-cuda=11.7 -c pytorch -c nvidia
   pip install huggingface-hub0.17.3
   pip install transformers4.34
   pip install psutil5.9.8
   pip install accelerate0.24.1
   pip install streamlit1.32.2
   pip install matplotlib3.8.3
   pip install modelscope1.9.5
   pip install sentencepiece0.1.99
   
2. 创建下载模型的文件，并下载模型

import os
from modelscope.hub.snapshot_download import snapshot_download# 创建保存模型目录
os.system("mkdir /root/models")# save_dir是模型保存到本地的目录
save_dir="/root/models"snapshot_download("Shanghai_AI_Laboratory/internlm2-chat-1_8b", cache_dir=save_dir, revision='v1.1.0')

3. 创建执行文件

import torch
from transformers import AutoTokenizer, AutoModelForCausalLMmodel_name_or_path = "/root/models/Shanghai_AI_Laboratory/internlm2-chat-1_8b"tokenizer = AutoTokenizer.from_pretrained(model_name_or_path, trust_remote_code=True, device_map='cuda:0')
model = AutoModelForCausalLM.from_pretrained(model_name_or_path, trust_remote_code=True, torch_dtype=torch.bfloat16, device_map='cuda:0')
model = model.eval()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 = [(system_prompt, '')]print("=============Welcome to InternLM chatbot, type 'exit' to exit.=============")while True:input_text = input("\nUser  >>> ")input_text = input_text.replace(' ', '')if input_text == "exit":breaklength = 0for response, _ in model.stream_chat(tokenizer, input_text, messages):if response is not None:print(response[length:], flush=True, end="")length = len(response)

4. 测试模型demo
   
   点评：能创作通话故事，但是故事主角有3个而不是2个，缺失了人物主角。

不知道是对齐的时候太严格了还是怎么样，能力有限
