If you install a new version but the previous one was imported. This will result in displaying which one is currently used.

import moviepy
moviepy.__version__

result:

'1.0.3'

(5) Install specific pre-release version in Python

pip install 'moviepy>=1.0.3' --pre

To check which is the installed version of a given Python package use:

from importlib.metadata import version
version('moviepy')

result:

'2.0.0.dev2'
