paperless Classifier stopped working

[gnissoer]

Hello, hope to get help in this forum. I asked already here: paperless-ngx/paperless-ngx#11058 and got the advice to ask again in this forum.

I moved my consume and media folders to my NAS and mounted accordingly. All works well, except the classifier. The System Status is showing an error and when I click on it, it is says "classifier_error": "[Errno 2] No such file or directory: '/opt/paperless/data/classification_model.pickle.part'" Note the .part piece of the filename.

I searched the docs and forums and found to delete the .pickle file and then to re-build by running python3 /opt/paperless/src/manage.py document_create_classifier. That causes error messages by python pointing to imap_tools and doesn't create a new .pickle file. See the details in the link above.

I got the advice to re-install the python dependencies.

Is there a way to fix my paperless setup and make the classifier work again?

Its an UV Tool. Not python3, with python3 you destroy maybe the most deps Created by UV. Look at old Issues, ive declared this several times - Look at source Code. Its all uv not Python

Thanks a lot for clarification, MickLesk, and sorry for my lack of knowledge.

With your answer and with this post #2192 (comment) I figured that I had 2 issues.

1. By replacing python3 with uv run in the above command, everything works again.
2. After deleting the celerybeat-schedule.db the hourly check started working again
