Tagging takes forever

[derritter88]

Hello @marcelklehr ,

I have installed the app last Friday and since then it is stuck with tagging only one use and not all.
Not sure if tagging takes so long or if there is any other issue.

it is stuck with tagging only one use and not all.

I'm not sure I understand you

In my Nextcloud log I see randomly a line saying "regonize for user xxx" but it stuckt with this single user.
No other user is being used.

Do you see tags being added? If tags are being added, then that's as fast as it can go in a background task. I'm working on a cli command that will do everything at once.

[marcelklehr]

The tagging speed depends on your hardware performance specs and the amount of images you have. Raspi and 1TB of images is gonna take a while.

I just had a look at the "real" log -> nextcloud.log and not just the online log display.
I can see that there is a progress - slowly but working.

Regarding hardware specs:
VM
24 GB RAM
8 cores (Epyc 7272)
~ 700 GB cloud storage

So I guess I just need to wait.

Just for info: The GUI says `

Warning	recognize	Classifying photos of user mhepp

`

[marcelklehr]

v1.3 now comes with a command line interface that allows running the classifier on full speed.

Thanks for the information - will do the update right now!

May I ask: Is this application only using the CPU or is it also able to use an existing GPU?

[marcelklehr]

It currently only uses CPU. But by default the cli will use all your CPUs, you can however also set a custom amount of CPUs.

[marcelklehr]

The admin user has access to a tag called "Tagged by recognize" to know which photos have been processed.

Would be great if this application would be able to use a GPU.
May I ask which php library your application uses?

Regarding cli: Is it better to create a dedicated cronjob for having the photo recognized or could this be done via the regular Nextcloud cronjob?

@marcelklehr regarding my library question:
Unfortunately I am not so deep into development - just remembered some Java stuff I have "developed" at high school.

May I just ask if pdlib would be suitable for this application?

I think the point of the cli is to do the initial bulk of photo classification, while the background job should be able to handle new photos as they are uploaded. If the background job is not enough, you can schedule the cli to run every night perhaps.

Would be great if this application would be able to use a GPU.

It's definitely possible, you can open a new issue for that.

I'm using tensorflow-js running inside Node.js.
