not working if jupyter_contrib_nbextensions are installed

[hoba87]

I tried to convert a Jupyter notebook to python script with jupyter nbconvert --to python ...

This gave me an error if outdated? jupyter_contrib_nbextension is installed:

Traceback (most recent call last):

    from notebook.services.config import ConfigManager
ModuleNotFoundError: No module named 'notebook.services'

However, when I uninstall it, it works.
So probably, the priority to use it should be downgraded or completely removed.

This issue is in jupyter_contrib_nbextensions and should be reported over there.
