nbconvert timeout on long computations

[cstjean]

When running a long computation through ipython nbconvert, I will get a timeout ERROR. For instance, with the notebook containing just one cell:

from time import sleep
sleep(120)

Running it with

ipython nbconvert Testing_IPython.ipynb --ExecutePreprocessor.enabled=True --to html --output Executed --output Testing_IPython.html

Yields:

[NbConvertApp] ERROR | Timeout waiting for execute reply
[NbConvertApp] ERROR | failed to run cell: Empty()
[NbConvertApp] ERROR | from time import sleep

It seems that the exception comes from this line, @tritemio. Is there any way to manually set the timeout? The documentation for nbconvert is out-of-date.

The timeout is configurable. Set c.ExecutePreprocessor.timeout in the config file, or pass --ExecutePreprocessor.timeout=180 at the command line.
