My run button seems to disappear randomly while working in a notebook.
Actively refreshing the page in the browser (firefox) helps to get it back.
Any clue what could cause this.
normal button bar
at random times, the play button disappears
I’m running Jupterlab 3.3.2 behind Jupyterhub proxied via nginx.
The user homedir is nfs mounted on the jupyterhub server
Since yesterday, the video playback button disappears quite frequently. For example, if I play a video, then stop the video, the playback button disappears.
It looks like the dom is actually modified since the placeholder for the button is still there.
I can’t find any hints in the logfiles to what could be happening.
For what its worth, I can just run the cells with enter.
I don’t think this has anything to do with my question
I have the same experience. Everytime I open a plain .py file in the editor, the “Run/Play” Button disapears. I have to close both and open the NB again, then it will be displayed again.
I made a ticket in play/run button disappears when switching between tabs · Issue #12292 · jupyterlab/jupyterlab · GitHub
I think it appeared in the triage. In between I reverted to 3.2.9 that does not have the issue
I can reproduce the issue on my local jupyterlab 3.3.2 installation on macbook using Chrome 100 without any ad blockers.
I also encountered this bug in 3.3.2, and it would happen in Chrome-based browsers whenever I switched tabs from viewing a notebook to some other tab in JupyterLab.
Upgrading to 3.3.4 appears to resolve this issue. Thanks -
