Kernel Error / Jupyter Missing “Python (dojo-env)” in kernels

PROBLEM:

  • **If you see a message like this when trying to open the environment testing notebook:
    **

  • OR if “Python (dojo-env)” doesn’t show up in Jupyter Notebook in EITHER:
    • The “New” menu on the Files tab in Jupyter.

    • or the Kernel > Change Kernel menu inside a Jupyter Notebook:

Solution

  • You missed a command after running the conda env create command during step 2, so let’s rerun the command.

  • First, shut down Jupyter Notebook

    • The quickest way is to go back to the Terminal/GitBash window that you used to start the notebook and press “control + C”
  • In your terminal/GitBash, make sure it says (dojo-env) above or next to your terminal prompt.
    • if not, on Mac run:
      • “conda activate dojo-env”
    • on Windows run:
      • “source activate dojo-env”
  • Then run the command below to install dojo-env as a kernel in jupyter:
python -m ipykernel install --user --name dojo-env --display-name "Python (dojo-env)"

Then, go ahead and boot up jupyter notebook and try again. It should now know the “Python (dojo-env)” kernel.
