pip upgrade all packages

Sometimes, we want to upgrade all the python packages installed, the following python script can help to upgrade all the packages installed.

Python

import pkg_resources
from subprocess import call

packages = [dist.project_name for dist in pkg_resources.working_set]
for pkg_name in packages:
    call("pip install --upgrade " + pkg_name, shell=True)

If you want to upgrade a package with dependencies, then run the following command.

See doc https://pip.pypa.io/en/stable/development/architecture/upgrade-options/

pip install --upgrade --upgrade-strategy=eager <package name>
