- 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.
Running this once, works fine. Run it a second time, get an error
import clr
clr.AddReference('System.Linq')
clr.AddReference('System.Collections')
- If there was a crash, please include the traceback here.
Reloaded modules: CLR, clr
