Ray tracing 3D preview problem

[Mio-TW]

Dear Sionna Team,

When I ran this tutorial, I suffered an issue for the "Open 3D preview".

 # Open 3D preview (only works in Jupyter notebook)
if colab_compat:
    scene.render(camera="scene-cam-0", num_samples=512);
    raise ExitCell
scene.preview()

The error message is:

How do I solve this problem? Thank you.

Hello @Mio-TW,

This issue has come up in the past, but I believe it was fixed in more recent versions of the dependencies we are using for the realtime preview.

Could you please try again after running:

python3 -m pip install --upgrade jupyterlab ipywidgets ipydatawidgets jupyterlab-widgets pythreejs
python3 -m jupyterlab .  # Start the server again

Dear @merlinND,

Could you try updating the ipykernel and ipython packages as well? I just tested locally and it works fine for me (in Chrome on Ubuntu 22.04).

Otherwise, I think it would be good to try in a fresh Python virtual environment, and to make sure that the Jupyterlab server that you are launching is using only the virtual environment's packages (to reduce the risk of accidentally using some older package versions that are installed elsewhere).

For some reason this error did not come up when running in Jupyter Notebook instead of Jupyter Lab.
