(1)run一个容器
命令:podman run -v /your/path/:/work/ --name="cpython" --privileged=true --dns=8.8.8.8 -p 22002:22 -it docker.io/nvidia/cuda:10.2-cudnn8-devel-ubuntu16.04
(2)安装python3.8
(2.1)让管理员开通访问外网权限
(2.2)查看系统版本信息:uname -a;cat /etc/issue;cat /proc/version
(2.3)ubuntu下,apt-get install python3.8,出现如下问题:
E: Unable to locate package python3.8-dev
E: Couldn't find any package by glob 'python3.8-dev'
E: Couldn't find any package by regex 'python3.8-dev'
解决办法:
apt-get install -y software-properties-common
add-apt-repository ppa:deadsnakes/ppa(或者add-apt-repository ppa:jonathonf/python-3.8)
apt-get update
apt-get install python3.8
(3)设置python优先级
(3.1)查看python安装路径:which python3.8;
update-alternatives --config python
#通过update-alternatives来设置默认python版本, 最后的参数1,2是优先级,数字越大优先级越高
update-alternatives --install /usr/bin/python python /usr/bin/python3.5 1
update-alternatives --install /usr/bin/python python /usr/bin/python3.8 2
(4)安装pip
(4.1)wget https://bootstrap.pypa.io/get-pip.py
解决:sudo apt-get install python3.8-distutils
(4.3)python3.8 get-pip.py
(4.4)查看版本:pip --version
(5)/usr/include/中没有python3.8版本的Python.h
安装:apt-get install python3.8-dev
