from packaging import version as pack_version ImportError: No module named packaging

[David Gabriel]

Dears,

I am running a python code that generates for me this error :

from packaging import version as pack_version
ImportError: No module named packaging

I googled it and I have found so many suggestions regarding updating 'pip'
and installing python-setuptools but all of these did not fix this issue.

Do you have any idea how can I solve this problem.
Thanks in advance.
