NotebookApp.iopub_data_rate_limit

Question

Hi -- I'm running a query within a Jupyter notebook for a 1 degree radial search within the DES catalog. I need to increase the NotebookApp.iopub_data_rate_limit for this query (warning message at end). While I know how to do this from the command line locally, it is not apparent to me how I can change it for jupyter notebooks opened online within datalab. Is there a way in which I can do this?

IOPub data rate exceeded.
The notebook server will temporarily stop sending output
to the client in order to avoid crashing it.
To change this limit, set the config variable
`--NotebookApp.iopub_data_rate_limit`.

Current values:
NotebookApp.iopub_data_rate_limit=1000000.0 (bytes/sec)
NotebookApp.rate_limit_window=3.0 (secs)

Hi Anthony,

It sounds like your Notebook is printing the full output to the Notebook itself.  Can you save the output to a file instead, and browse the file either in a Terminal on the Notebook server or by downloading to your local machine?

If you could post a copy of the cell that is producing the crash warning, that could help diagnose the issue further.

Cheers,

Knut

The default value is known to be too small for many visualization applications, and while I don't know the particulars of what you are doing to cause the problem I did significantly raise the default value used by our notebook server.  Please let us know if the problem continues, some more detail on what is triggering the error would also be useful.
