Thanks for the vid however I can't execute python script after publishing the application any tips?

Hello! not sure what do you mean by "publishing". create(build) .exe file? Just checked,works fine. have you tried this from comments below? Thanks!
The script (in this example it's just a text file with .py extension and command: print("Hello Python") has to be in same directory,where your VB project is(not python.exe). in this example location of the script was C:\Users\User_Name\source
epos\WindowsApp24\WindowsApp24\bin\Debug\Hello.py

I'm stuck (and kind of abandoned the whole thing) because I couldn't find a way to change the conda environments and call the scripts from VB that are created for different than conda "base" environment. and even if for example Tensorflow or Keras are installed in conda "base" environment the scripts,that are calling those libraries won't execute. If you , or anyone, by any chance find a solution please explain it here or create your own video. I'm very new to the Python and can't find anything in relation to VB + Python combo.Thank you!
