Running script with CLR a second time gives "RuntimeError: Failed to initialize Python.Runtime.dll" #2099
Description
Environment
- Pythonnet version: 3.0.1
- Python version: 3.10.9
- Operating System: Windows 11
- .NET Runtime: 4.8
Details
- Describe what you were trying to get done.
I'm using the Spyder IDE with Conda. When I run a Python script to import CLR and add references, the first time it works. However, if I re-run, then the second time it fails with an error, and I have to restart my Spyder IDE for it to work again.
- 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.
Running this once, works fine. Run it a second time, get an error
import clr
clr.AddReference('System.Linq')
clr.AddReference('System.Collections')
