Notebook doesn't open when jupyter server runs on pypy3 #7171
Comments
Thank you for opening this issue @iamshreeram! Are there any other notebook servers that you have running (can check with |
Thank you for providing the additional information @iamshreeram! From the notebook call, there was a suggestion to try to isolate the problem further by running the kernel on pypy rather than the server itself if that is something you can try? |
Hi @RRosio , Same issue when running on pypy as well. |
@jtpio , Thank you for including this in your weekly meeting. Is the meeting scheduled for 8:30 AM PT on 12/13? If possible, may I join and present the issue during the meeting or after the meeting ends? |
Thanks @iamshreeram for opening this issue 👍 Next week is a bit of a special case actually, since there will be a Jupyter community call instead of the regular dev meeting: jupyterlab/frontends-team-compass#223 Any can join so if you feel like coming feel free! Although community calls are more about showing demos, meeting other members of the community rather than discussing issues. But the week after there should be the dev meeting as normal. |
Regarding the issue itself, is there a reason for running the Jupyter Server with pypy? The comment above was suggesting to run the kernel with pypy instead of the server, which is where the performance gains of using pypy would be more visible (if you're looking for better performance). |
I can utilize pypy as the kernel in Jupyter. However, I remain uncertain about the root cause of the |
Usually that means there is already another application using that port. Maybe an old Jupyter Server process that did not terminate correctly? It could also be because there is a Docker container exposing that port already running on the system. |
I have validated this. The only process using the port is the pid of jupyter. However, I am closing the issue as I have successfully run pypy as a kernel in jupyter. Thank you for your assistance, @jtpio |
OK good to hear, thanks @iamshreeram for your patience and for providing useful details! |
