The reason for not accepting the answer is that there is a question in the python environment. |

I had a similar issue, but a completely different environment, so I'm not sure if it applies. By default, pythonnet works with the .NET Framework environment, not core. Instructions for loading core: In my environment that alone isn't enough, because some of my dependencies could work with .NET 6 or 7, but there was no directive either way. My options were to load the .NET 7 runtuime or add in a reference to the runtimeconfig. You're running out of a .NET 6 application, so I would think the runtimeconfig.json for your app would be used? |

PythonPath, We must use ":" instead of ";" in Linux |
