Got UserWarning: K3DBackend only works properly within Jupyter Notebook in JupyterLite

[ruoyu0088]

Here is the notebook that shows the warning:

https://ruoyu0088.github.io/jupyterlite/lab/index.html?path=demo%2Flibs%2Ftest_spb.ipynb

the get_environment() function check Notebook with following code:

        shell = get_ipython().__class__.__name__
        if shell == "ZMQInteractiveShell":
            return 0  # Jupyter notebook or qtconsole

however, in JupyterLite, get_ipython().__class__ is pyodide_kernel.interpreter.Interpreter.

Hello @ruoyu0088 ,

I need to ask you a few questions, as I'm not familiar with pyodide.

1. Why are you using Pyodide?
2. When setting up Pyodide, does it come with jupyterlite installed, or do you have to install it manually?

Hi @Davide-sd,

JupyterLite and Pyodide only require a web browser, so it’s very easy to share notebooks with others without asking them to install a Python environment.

I set up my own JupyterLite + Pyodide site and deployed it on GitHub Pages. You can find the project here:

https://github.com/ruoyu0088/jupyterlite

You can access the live site at:

https://ruoyu0088.github.io/jupyterlite/lab/index.html

And here is the URL for the notebook that demonstrates the warning issue:

https://ruoyu0088.github.io/jupyterlite/lab/index.html?path=demo%2Flibs%2Ftest_spb.ipynb

Just open the URL, wait for the kernel to finish loading, and then you can run the demo code.

I tried opening the file you linked, but it appears it was removed. Anyway, I would try to skip those checks by setting this:

from spb import *
KB.skip_notebook_check = True

# your plotting commands
