Linux X86自带python环境下opencv+torch+torchvision安装

• 1.pip安装
• 2.opencv安装
• 3.torch安装
• 4.opencv安装

安装pip

sudo apt install python-pip

后续利用pip安装完库，pip list查看库存在，但是import 时又显示库不存在，所以又安装了pip3

sudo apt install python3-pip

后续利用pip3安装opencv时出现以下错误：Command “python setup.py egg_info” failed with error code 1 in /tmp/pip-build-jg8usrjf/opencv-python/

解决方法是升级pip

pip3 install --upgrade pip

pip3 --default-timeout=100 install opencv-python -i http://pypi.douban.com/simple/ --trusted-host pypi.douban.com

pip3 --default-timeout=100 install torch==1.6.0 -i http://pypi.douban.com/simple/ --trusted-host pypi.douban.com

pip3 --default-timeout=100 install torchvision -i http://pypi.douban.com/simple/ --trusted-host pypi.douban.com
