Hi There,
Timeouts can occur when executing a workflow that uses the Python tool if any of the notebook cells contain intensive operations requiring 31+ seconds of execution time.
The error message shown in the Alteryx message log:
Error: Blobby Output (9): Tool #2: [NbConvertApp] Converting notebook C:\ProgramData\Alteryx\Engine\96e4c0ab-5610-4858-80e0-3625bb421cec\20\workbook.ipynb to html

TimeoutError: Cell execution timed out
Does anyone have any creative ideas on how to adjust the timeout or eliminate it? Nbconvert has parameters for these timeouts, however I'm unsure how they can be adjusted when Alteryx Designer orchestrates the process...
Thanks,
Ryan
