pkg_resources is deprecated as an API

[aleray]

Hello,

using Python 3.11, Pip 23.3.2 and setuptools 69.0.3 I get this error:

INFO    -  DeprecationWarning: pkg_resources is deprecated as an API. See https://setuptools.pypa.io/en/latest/pkg_resources.html

The error is raised by this statement:

Thanks!
