Failed to load notebook

TylerT — Mon, 28 Nov 2022 18:10:50 GMT

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

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.

@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.

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

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

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

@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?

Re: Failed to load notebook

TylerT — Mon, 19 Dec 2022 18:07:17 GMT

UNC path.

Re: Failed to load notebook

HannesZiegler — Mon, 19 Dec 2022 18:17:27 GMT

Interesting, to confirm that is the cause of notebooks not loading, can you try running a notebook from a local path?

Also, are you able to upgrade to Pro 3.0.3 (just in case that resolves your issue)?

Thanks,

No dice running from C: drive. Upgrading is easier said than done. I'll give that a try when allowed. Thx.

HannesZiegler — Mon, 19 Dec 2022 20:02:34 GMT

Okay, that rules out UNC paths causing an issue.

So far it looks like this is an issue with your particular setup and not Pro.

Does your organization have a strict firewall policy? Check if it is blocking localhost in any way, in particular make sure it is not blocking traffic through localhost:8778. This is the default used by notebooks in Pro.

Besides this, let me know if upgrading to Pro 3.0.3 resolves your issue.

Hi all ( @TylerT and @HannesZiegler ) - I just had (breifly) and resolved the same issue. Hopefully this can help you Tyler. As Hannes said though, you may not have a config file. I may have created one in the past - I do not recall. BUT, I do have one now and changing the path to our new network root in the config file fixed the issue.

# c.NotebookApp.notebook_dir = r"c:\path\old_network_drive\to\dir" c.NotebookApp.notebook_dir = r"c:\path\new_network_drive\to\dir"

In my case, I absolutely know what happened. We have a cloud-based server through Box (that's a company). Our IT just changed the base directory name, and immediately Notebooks failed to load. My troubleshooting was initially like yours - I copied my Notebook file (.ipynb) to my hard drive and tried loading it in Pro from there. Same result - wouldn't open.

Perhaps try one more time to discover your jupyter_notebook_config.py file by opening the command line and entering command: jupyter --paths - this should list a few directories. Mine was in c:\Users\myprofile\.jupyter. The config file was located there.

Also note that I recently "upgraded" from 2.9 to 3.02 and did NOT encounter this issue.

Hope that helps.

@ZacharyUhlmann1, Thank you. I checked again and had no luck finding the jupyter_notebook_config.py file. When you say you have one now, are you suggesting that I create one for the fix?

Re: Failed to load notebook

ZacharyUhlmann1 — Thu, 09 Feb 2023 20:36:00 GMT

I wasn't...but maybe? A few thoughts: 1) So same problem still? 2) are you able to open the .ipynb files in a text editor? For instance, PyCharm was able to open my Notebooks with proper formatting. So I know the file itself was fine. 3) My issue was 100% a path on the config file. I don't know enough about Jupyter, but in my case the path in config file was no longer in existence. Did IT rearrange directories around the same time as the issue happened?

It sounds like it may be related to the upgrade, but in my case, from 2.9.5 yo 3.01 then 3.02 I had no issues.

But making a config file and checking it may not be a bad idea? Please let me know what you find out.

Re: Failed to load notebook

TylerT — Fri, 10 Feb 2023 15:01:00 GMT

Can somebody share the entire contents of their config file? Thank you.

Re: Failed to load notebook

ZacharyUhlmann1 — Fri, 10 Feb 2023 15:52:46 GMT

Hi @TylerT my config file is 1300 lines. Almost certain it was autogenerated using the command line command explained here: https://jupyter-notebook.readthedocs.io/en/stable/config_overview.html

In my initial response, the code changing the c.NotebookApp.notebook_dir was what fixed it for me. Line 393 in jupyter_notebook_config.py. In my case, the path originally listed was no longer valid so I changed it.

Re: Failed to load notebook

TylerT — Sun, 12 Feb 2023 14:52:16 GMT

Thx. If the config file was a two liner, I'd give it a try, but given the facts you stated, it's a dead end for me. I have no config file.

I am continuing troubleshooting various ideas. I just upgraded to 3.0.3 successfully, although that did not fix the notebook fail. Working on blockers now, but still taking ideas. Thx.

Re: Failed to load notebook

TylerT — Tue, 14 Feb 2023 18:55:08 GMT

@HannesZiegler et al,

It was mentioned above that ArcGIS Pro embedded Notebook uses localhost:8778 as a default. How can I check exactly which localhost my ArcGIS Pro is using in case it's not using the default? Thank you.

I am fairly new to GIS Pro 3.03 from ArcGIS 10.6.x desktop (agency lack of interest in migrating) and new to python and Jupyter notebooks. So forgive my nonprogrammer type answer.

I did have the same error after I had duplicated my environment and downloaded other conda Packages(r-ArcGIS bridge among others). Jupyter Notebooks would open from the Python Command Prompt in a browser, but I would get the same error you did if I tried to open them in GIS Pro.

Along with trying some of the suggestions in this post and others, I updated Jupyter from the Python Command Prompt. That got rid of the error for me, but notebooks opened blank (no command line or menu items) in GIS Pro. I could not see the content or edit them.

To trouble shoot this, first, I uninstalled GIS Pro, reinstalled it, updated it to 3.03, then duplicated my environment and tried to add some packages. Same error. So then I reactivated the default GIS environment. When I did this, the notebook worked. I suspect there were conflicts with some of the packages I had installed.

Update: To trouble shoot this further, I wanted to try to figure out what packages were causing this. I did yet another a fresh single user install of ArcGIS Pro 3.0, left the default environment alone, updated to ArcGIS Pro 3.03. The notebooks worked with no error. I then duplicated my environment, without adding any conda packages and the notebooks worked. Then I installed r-arcgis-essentials. Upon restart I got the same error again.

So I suspect that in my case at least, the installation of r-arcgis-essentials along with its dependents is what is killing the notebooks inside ArcGIS Pro 3.03. Now to try to figure out what in this metapackage is causing the issue.

@TylerT Did you try this? Specifically, create a brand new project (map, whatever is quickest). Then make a Notebook. Do this all on your hard drive. Save the project, close and reopen. Are you still encountering the same error with the one-off Notebook you just created? If that works, seems @HannesZiegler Network troubleshooting may help isolate the issue.
