Shared Portable Python Environment

I need a fully portable Python 3 virtual environment that sits on our network share (\\my_host\Shared) and can be executed from three Windows machines that have no local Python installation.

Here’s what has to happen:

1) Create virutal environment in locally
2) Copy the virtual environment to "Shared" folder
3) Copy the sample script to shared
4) run the python and sample script from different PCS ( I think we need to map the logical drive to access )

We tried :
1) Created python virtual environment locally
2) Copied to shared
3) Created the logical drive and mapped the shared drive (net use Z: \\my_host\Shared /persistent:no)
4) z:\Shared\pyenv\Scripts\python.exe --version ( it works )
5) when we try to run sample.py ( it works where we have created virtual environment ).
6) It is not working in another PC it is giving error "No python" where there is no python installed.
