Failed to load notebook

[TylerT]

I am getting this error upon any new or existing notebook open, within any project.  It's a global issue.  Any ideas how to fix?  The error starting occurring upon upgrade to version 3.0.2.

Thank you.  Tyler

ArcGIS 3.0.2

BTW: The stand-alone jupyter lab/notebook is working fine including Arcpy and ArcGIS for Python modules.

Hi @TylerT, make sure that there haven't been any changes to the Jupyter configuration file jupyter_notebook_config.py, see the FAQ.

[TylerT]

@HannesZiegler ,I have not knowingly modified jupyter_notebook_config.py file.  Where is it typically located, and what should the c.NotebookApp.ip or c.NotebookApp.port configuration options be set to?  Thx.

[HannesZiegler]

It's typically in your user profile under the .jupyter folder.

1. Hit windows key or click into the windows search box.
2. Type %userprofile%.
3. Locate & open .juypter folder.
4. Locate & open jupyter_notebook_config.py in an editor.

Both keys should be commented out (prefix the # symbol).

I have the same issue. I am not sure if it is caused by the citrix machine, it worked in bomgar.

In a more complex case where this is only happening in an environment like Citrix, it makes sense to try and work through this with support. I'm not aware of any reproducible cases we have when the machine is typically configured and the installation is fully clean other than the configuration being manually changed like Hannes mentioned.

Cheers, Shaun

@HannesZiegler,

Hmmm, interesting.  I have no jupyter_notebook_config.py in the location described, or anywhere I can find.  Is this the problem, perhaps?

Adding to the evidence, another user in my group is experiencing the exact same issue upon upgrading to 3.0.2.

Thanks for engaging...much appreciated.

No, if you haven't had occasion to mess with the configs, then there won't be a config to mess with 😄 (it has to be intentionally created with the command jupyter notebook --generate-config).

Are your notebooks located locally, or on a server or network location with a UNC path?

[TylerT]

UNC path.
