Python tool NbConvertApp Timeout

[Lunalight]

Hi all,

I'm running a script with the Python tool in Alteryx, however, it quits after 30s. I get the error [NbConvertApp] ERROR | Timeout waiting for execute reply (30s). At least, I think that's the problem (see complete error message below. After browsing the interwebs, as one does, I noticed that it's possible to increase the timeout time (link). How can I do this with the Alteryx Python tool. Can I change something in one of the .py files in site-packages? Which one? And most important, will changing that solve my issue?

Hi @Lunalight,

Thanks for posting!!

You are right, 30s is the default configuration for running cells in Jupyter.

I would suggest to use one of the following solutions as a workardound:

@PaulN Thanks! That was exactly what I was looking for

Hi all, I've put an idea to have the default timeout changed as I really don't like the current workarounds:
