Getting an error when calling load more than once #2078
Description
Environment
- Pythonnet version: 3.0.1
- Python version: 3.11.1
- Operating System: Windows & Linux
- .NET Runtime: net6.0, net7.0
Details
- Describe what you were trying to get done.
I have 2 libraries that are packaging some C# code with pythonnet as a dependency so that they can be used from Python without issues. In both libraries I call load("coreclr") in the __init__.py. When a user try to load both libraries at the same time pythonnet throw an exception. It wasn't happening with pythonnet version 2 so I suspect that this is a bug of pythonnet version 3.
- 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.
from pythonnet import load
load("coreclr")
load("coreclr")- If there was a crash, please include the traceback here.
