Sure
1) Create a virtual environment ("python -m venv")
2) Activate
2) Pip install some modules
3) Try to use them form inside an embedded application (e.g. the one I attached)
4) Do it in Linux and Windows
Result
Works in Linux, fails in Windows.
Reason in site.py
https://github.com/python/cpython/blob/73870bfeb9cf350d84ee88bd25430c104b3c6191/Lib/site.py#L462
sys.executable is used to construct the correct search path.
Looking at the sys.path from inside an embedded application is very instructive and you can see in
the first post why the failure in windows.
