I’ve got a custom jupyterhub deployment up at https://lab.amdatascience.com with environments that support RTC.
Since this is an early beta, I wanted to see if anyone here can help me test this out to find any bugs or issues we could bring up to the jupyter lab dev community i.e. Damaged notebook (duplicate cells) in RTC-active hosted hub · Issue #14031 · jupyterlab/jupyterlab · GitHub
Let me know if you have any questions
Ran into an issue where some notebooks appeared to be blank and I couldn’t save. Seems related to this Non-empty notebooks appear as blank · Issue #13930 · jupyterlab/jupyterlab · GitHub.
Hopefully being fixed in jupyterlab v4+, currently using v3.6.3.
Also ran into an issue where python3.10 RTC wouldn’t work correctly when sharing workspaces with others. Collaborators would be able to create files and start kernels, but wouldn’t be able to actually run anything via terminal or in notebooks. It seems to have sorted itself out after a day, but an odd issue nonetheless.
