InternLM2-Chat-1.8B 模型测试

本文主要是介绍InternLM2-Chat-1.8B 模型测试，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

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

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
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')

创建执行文件
