VS Code not registering that ipykernel is installed

Question

I am trying to run Jupyter notebook files in VS Code but they fail to run due to the error:

IPyKernel not installed into interpreter Python 3.8.5 64-bit

However as shown, I have installed the package.

I have checked similar questions (one, two, three, four) but the solutions don't fix this issue.

Any ideas how to fix this?

Answer 1

The solution for me was running this code in command prompt

pip install --upgrade ipython

The problem I think is related to a conflict with prompt-toolkit versions. Try it and let me know if it helps you.

Answer 2

The upgrade of 'traitlets' package caused this. You need to downgrade it from '5.0.0' to '4.3.3' version through this command:

python -m pip install 'traitlets==4.3.3' --force-reinstall

You can refer to this page for more information.

Answer 3

Try to install it:

pip install -U ipykernel

Answer 4

You need to select the python interpreter of the environment in which you installed ipykerenel

Answer 5

I had the same issue and spent the whole week trying to resolve it. What worked for me was installing the Jupyter dependencies for anaconda:

conda install jupyter

I installed this in my base environment. After this VSCode worked without any errors.

Answer 6

I had same problem, while trying to run notebook on vs-code. resorting to older version of jupyter notebook extension worked for me

Answer 7

What worked for me was to change the environment to the Conda Env instead of the suggested one. see picture below.

good luck!

Answer 8

I reloaded my Jupyter Extension on VS code and that solved the issue.

I tried running pip install --upgrade ipython before and didn't work but it might have played its role when after reloading the extension
