[Error fix] Solved "The kernel failed to start due to the missing module 'IPython'. Consider installing this module. Click here for more info." (feat. VSCode Jupyter)

# Problem

When using a Jupyter notebook file in Visual Studio code with the Jupyter extension I receive the error:

The kernel failed to start due to the missing module 'IPython'. Consider installing this module. Click here for more info.

# Solution

First uninstall all jupyter related modules: (from: https://stackoverflow.com/a/52912244/1516331)

python3 -m pip uninstall -y jupyter jupyter_core jupyter-client jupyter-console jupyterlab_pygments notebook qtconsole nbconvert nbformat jupyterlab-widgets nbclient ipykernel ipynb

 

And then reinstall ipykernel. I'm using VScode so when I run a cell, VSCode asked me to installipykernel. The following should work the same alternatively:

conda install -c conda-forge --update-deps --force-reinstall ipykernel -y
pip install jupyter
