Do you mean that your python code is running another python program
via subprocess?

You would need to provide a PATH that does not include the venv so that env
works as expected.

Or are you running the program from the command line after activating the
venv?

I create the venv and use it to run the program using
 <path-to-venv>/bin/python program.py without activating the venv

At least for Fedora it does not allow packages to install programs
that use /usr/bin/env because of issues like you are seeing.
