Originally, Jupyter notebook was running well without any problems. But after installing tensorflow and keras today, it doesn't work.

Error message:

There is a problem with your importlib_metadata package, you can try uninstall it first and then forcing out a new installation with the following commands:

pip uninstall importlib_metadata 
pip install importlib_metadata --force-reinstall

It worked for me.

For me, the same error happened after VSCode proposed me to install a tensorboard plugin and I pressed yes. (MacOS 11.4, Conda 4.10.3)

It appears that it introduced some kind of version mismatch for multiple packages in the environment.

The following fixed the problem:

conda update --all

This is a problem with the Anaconda version upgrade. You can solve this with the following command that worked for me.

conda install -c conda-forge importlib_metadata
