Unfortunately, under Ubuntu, we cannot use the PYTHONHOME and PYTHONPATH variables. If you use these variables, you will get the \"ModuleNotFoundError: No module named 'encodings'\" error. If you use your own packages, such as creating a class structure and importing it into your project file, you must copy it to the \"dist-packages\" folder.\u003c/p\u003e","upvoteCount":2,"url":"https://github.com/pythonnet/pythonnet/discussions/2147#discussioncomment-5731899"}}}
