voila timeout on long computations
Hi,
I am trying to convert a notebook with voila with some calculations in it that take a few minutes. I am getting this error:
[Voila] ERROR | Timeout waiting for execute reply (30s).
For nbconvert you can change the timeout with --ExecutePreprocessor.timeout=180 (or another time) at the command line. Is there a similar option in voila?
Thanks,
John

This looks like it is identical to #125 so I am assuming it is still an issue?

I am also running into this issue. Pretty much any cell which runs for longer than a few seconds seems to crash the whole render process. This leaves Voil谩 unusable for me.
Below is the stack trace.
[Voila] ERROR | Timeout waiting for execute reply (30s).

This is solved in #240, pass --ExecutePreprocessor.timeout=180, if it does not solve your problem, feel free to reopen.

Thanks, that fixed it immediately! I had found the other issues, but hadn't figured out how to pass it through Voil谩 yet. Thank you for the swift reply.

Passing the argument works in command line, but what if we want to open the voila dashboard from jupyter notebook. How do we proceed then ?
