The module 'notebook_intelligence' could not be found

[hgrosselindemann]

I successfully installed the extension and jupyter lab links it, however, it can not load the extension and I get the following error when starting jupyter Lab:

notebook_intelligence | error adding extension (enabled: True): The module 'notebook_intelligence' could not be found (cannot import name 'Distribution' from 'importlib_metadata' (unknown location)). Are you sure the extension is installed?

jupyter lab extension list gives a similar error

notebook_intelligence enabled
    - Validating notebook_intelligence...
       X The module 'notebook_intelligence' could not be found (cannot import name 'Distribution' from 'importlib_metadata' (unknown location)). Are you sure the extension is installed?

Do you have an idea why this appears? Is this dependant on some package versions? I think everything is up to date.
Thank you, I would really like to try your extension!
