Unpickling error? - Githubissues

anshver92 commented 3 years ago

After installing using pip install wbdata I am getting a pickling error on doing just a simple import wbdata as wb command:

UnpicklingError                           Traceback (most recent call last)

UnpicklingError: pickle data was truncated

When I had previously installed this package I remember I did have to restart the kernel for something because it was being too slow. Could something have become corrupted like this? I tried creating a new environment and reinstalling but this didn't work either. Thanks for any help!

Maybe perhaps there is a way of clearing that cache? My guess is that would sort it out?

Yes, that will solve that for now, I'll also open an issue to do it automatically on a failed load. What operating system are you using?

Yep so confirmed I located where the cache was being stored. Deleted the folder, uninstalled the package and reinstalled it and it seems to work. My OS is Windows 10.
