Problem description

Platform: Windows 10 professional edition, anaconda3

When starting the Jupiter notebook, there is an error message, as follows:

ModuleNotFoundError: No module named  jupyter_nbextensions_configurator

Although the jupyter lab can still be used when it is opened, the error message is always a hidden danger. Therefore, after searching the data, the following solutions are found

Solution:

python -m pip install --user jupyter_contrib_nbextensions

#jupyter contrib nbextension install --user --skip-running-check

python -m pip install --user jupyter_nbextensions_configurator

#jupyter nbextensions_configurator enable --user

Only running the above two commands solves the problem of error reporting.
