How to "reset" Recognize and start from scratch

It seems that Recognize “remembers” forever in the “oc_appconfig” table where it last stopped and what it recognized already, making it impossible with app buttons or occ commands to start all over, since it clearly just continues with the newly uploaded pictures. In other words: there is NO (easy available) hard reset!

This is not the case. Let’s avoid spreading falsehoods and ask questions before drawing conclusions.

There is an easily available hard reset and it’s even documented in the admin settings of recognize:

In order to reset recognize:

1. clear all currently scheduled background jobs:

occ recognize:clear-background-jobs

(and wait for any currently running cron.php instances to stop)

2. delete all faces and face clusters:

occ recognize:reset-faces

3. remove all tags from files tagged by recognize:

occ recognize:reset-tags

4. (optionally) Delete all tags used by recognize

occ recognize:cleanup-tags

Then, to trigger the background-job crawler for all files again, run

occ recognize:recrawl

or run

occ recognize:classify

which will do a full synchronous run over all files and will take a long time.

If these steps don’t work, the next step is to file an issue on GitHub - nextcloud/recognize: 👁 👂 Smart media tagging for Nextcloud: recognizes faces, objects, landscapes, music genres

(The appconfig flags you mentioned are only there for debugging purposes)
