Problem with Deep Learning and update to ArcGIS Pro 3.1.1.

[WilliamHarbert]

Hello, I was using Deep Learning (installed for ArcGIS Pro 3.1 from the github site), but when I updated to ArcGIS 3.1.1 I get the errors shown below from all of my notebooks.   This has stopped my work.

Could someone please help me understand how to fix this?

Here are the errors:

# Import necessary ArcGIS Python API tools:

from arcgis.learn import SingleShotDetector, prepare_data

I am uninstalling everything following the directions on the github site.  I am now reinstalling everything and will update everyone.

I installed everything from scratch.  First I installed arcgis Pro 3.1.  I then updated 3.1 to 3.1.1 and I then installed the Deep Learning tools for 3.1 from the github site. 

Now I cannot load any notebook, including a new empty one.  The error reads "Failed to load notebook". 

Any thoughts or suggestions would be greatly appreciated!

I also updated the latest version of arcgis pro, but when I launch the model training tool after producing the training data, the software crashes after I select the training data. I tried several times but to none success. I also tested the same data in the 3.0.1 version and it runs fine.

Thank you for this comment in the thread.  I'm not sure how to fix this.  I found another thread with basically the same problem, but it was never resolved either.  Question is still unanswered. 

I'm not sure what do to.  I've uninstalled/restarted/installed the software multiple times now.  Deep Learning simply will not work after this update to ArcGIS 3.1.1

BTW, I tried to solve this problem by uninstalling the latest arcgis pro and installing the 3.0.2 version. since I need to re-install the suitable library file that for 3.0.2, however, there is no official program to uninstall the library previous version. Even, it still unwork when you delete everything that contain arcgis pro in your pc after run uninstall program of arcgis pro. Maybe, reinstall windows is the simple way.

Thank you for this idea. 

Unfortunately I cannot downgrade to ArcGIS Pro 3.0, that's just impossible.  I saved my data in the 3.1 format too.  Also, reinstalling all of WIndows is not an option because of the many other applications I have installed on this workstation.

I'm currently having the same issue with Pro 3.1. Reinstalled as well to no avail.

I updated to 3.1.2 and repaired the Deep Learning parts (by relaunching the DL installer after reboot).  I cannot even open a notebook.  No change.
