It appears that `kernel.js` is not executed at all, otherwise there should be some error message for the execution of `kernel.js`. What do you see in `/home/.local/share/jupyter/kernels/sos`? Could you try...

ok, I found a Ubuntu 18.04 VM with conda 3.6, ran ``` conda create -n test_sos python=3.7 conda activate test_sos pip install -U sos sos-notebook sos-python sos-bash bash_kernel python -m...

I do not know what you did to resolve the problem but I am glad that sos notebook works for you now.

This is a known issue for jupyterlab 4. It has some api change that I have not had time to investigate.

I have a deadline for this Thursday but can work on this afterwards. You can downgrade jupyterlab for now if you need sos to work now.

JLab 4.x is now supported, although syntax highlighting is still pending.

Can you try to switch to jupyterlab? I apologize but the notebook interface is deprecating and so it our support for sos-notebook.

Just add that this also prevents the use of matlab in a multi-kernel notebook (https://github.com/vatlab/sos-matlab)

You guys can at least have a look at the official sos-notebook docker image and compare, right?

Yes, I am talking about [the official sos-notebook docker image](https://vatlab.github.io/sos-docs/running.html#content). I can tell it is using jupyterlab 3.6.1 though. I can modify the docker file and upgrade it to jupyterlab...
