Description
Environment
- Pythonnet version: 3.0.0-preview2021-12-25
- Python version: 3.9.10
- Operating System: Windows 10
- .NET Runtime: 4.7.2
Details
- Describe what you were trying to get done.
Embed python into C# using 32bit python.
- What commands did you run to trigger this issue? If you can provide a
Minimal, Complete, and Verifiable example
this will help us understand the issue.
Example assumes python3.9.10 32bit embed to be extracted to ./python
Python.Runtime.Runtime.PythonDLL = "./python/python39.dll";
Python.Runtime.PythonEngine.PythonHome = ./python/python39.dll;
Python.Runtime.PythonEngine.PythonPath = $"{PythonEngine.PythonPath}{Path.PathSeparator}.";
Python.Runtime.PythonEngine.Initialize();Last line causes an access violation after preview2021-12-25 (preview2021-12-03 works).
python3.9.10 64bit embed version of python does not cause the same issue.
- If there was a crash, please include the traceback here.
