python环境配置 pip和conda常用指令

最好手动升级，如果全升会出现兼容性问题

import pkg_resources
from subprocess import call
 
for packages in [dist.project_name for dist in pkg_resources.working_set]:
    call("pip3 install --upgrade " + ''.join(packages) + ' --user', shell=True)

pip升级单个包

pip install --upgrade < packages >

conda升级单个包

conda update < packages >

pip列出过期包

pip list --outdated

删除虚拟环境

conda remove -n  < packages >
