> Following Redhat's commendations, I want to install my (somewhat complex) software into /opt/my-software. To make it easier for users to use the software, my idea was to setup a virtual environment in /opt/my-software. Thus users can easily use /opt/my-software/bin/python and have the library provided by my-software available. My Software also includes some scripts, which will also reside in /opt/my-software/bin and refer to /opt/my-software/bin/python. This will avoid to require users to set up PYTHONPATH when thy want to use MY Software.

If you are packaging the code then I do not see the need to use a venv at all.

Have the RPM install all the pythone code and dependencies and also install a short script that
sets up PYTHONPATH, LD_LIBRARY_PATH, etc and execs the python3 <main>.py.

Note: you usually cannot use pip when building an RPM with mock as the network is disabled inside the build for
security reasons.

I package two of my projects this was for Fedora as RPMs.
