Minimal package requirements to run a jupyter notebook

[skwde]

Lately I have been running into some issues with environments and jupyter notebooks where I am asked to install ipykernel into the environment even though it is already installed.

It is not clear to me what the minimum requirements actually are from the current sources of information:

• https://code.visualstudio.com/docs/datascience/jupyter-notebooks#_setting-up-your-environment mentions jupyter
• https://github.com/microsoft/vscode-jupyter/wiki/Jupyter-Kernels-and-the-Jupyter-Extension#python-environments mentions ipython and ipykernel
• https://github.com/microsoft/vscode-jupyter/wiki/Installing-Jupyter mentions jupyter may be required.

Note,

• jupyter requires ipython and ipykernel.
• ipykernel requires ipython.

So which one is it? What are the minimum requirements with versions?

You need to install the latest version of IPyKernel and all of the related dependencies.
Use pip install ipykernel or the like, as to what the related dependencies are depends on the ipykernel package itself.

So which one is it? What are the minimum requirements with versions?

Closing this issue as this has been answered.

@DonJayamanne thanks for the reply.

By latest available version I assume you mean latest version in the environment.

Can you please also clarify the meaning of "jupyter may be required" as mentioned https://github.com/microsoft/vscode-jupyter/wiki/Installing-Jupyter. In which cases might jupyter be needed?

ning of "jupyter may be required" as mentioned

This is when some of the native modules for zmq do not work on your platform.
Its a little technical, but if you get promtped to install jupyter, thats the easiest way to tell that the native modules do not work on your platform.
