配置深度学习虚拟环境

Previous PyTorch Versions | PyTorch 

os库、shutil库，fnmatch，time,sys内置，不用安装，

依次安装cv2库、torch库、PIL库、numpy库、matplotlib库

#python3.7 cuda11.6
pip install opencv-python==4.4.0
pip install pillow
pip install numpy
pip install matplotlib
pip install GDAL-3.4.2-cp37-cp37m-win_amd64.whl
pip install torch==1.12.0+cu116 torchvision==0.13.0+cu116 --extra-index-url https://download.pytorch.org/whl/cu116

安装torch直接复制网站，直接pip install torch==1.12会下载为cpu版本的

下载太慢，直接去网站下载
