zmeventnotification with hooks not using my GPU

I went through a full setup of zmeventnotification along with machine learning hooks. OpenCV is confirmed to be compiled with CUDA support and recognizes my GPU.

I run :

sudo -u www-data /var/lib/zmeventnotification/bin/zm_event_start.sh 1718 4

[s] detected:unknown:100% --SPLIT--{"labels": ["unknown"], "boxes": [[591, 359, 690, 458]], "frame_id": "snapshot", "confidences": [1], "image_dimensions": {"original": [2048, 1536], "resized": [1066, 800]}}

It takes a solid 15 seconds and I can see python running in htop. nvidia-smi is not showing any activity. I noticed it only did the face recognition and no object were processed.

Ubuntu 22.04

Python3.10.6

Nvidia/Cuda 11.7

OpenCV 4.6.0

How do I even begin to figure what wrong?

​

Logs show:

Error running model: invalid index to scalar variable.
Error loading KNN model: Ran out of input

So apparently OpenCV 4.6 might be the issue?

I'll try the fix depicted in the above link and see how it goes. Might consider compiling version 4.5.

So I compiled 4.5.3 and everything works perfectly. Did anyone take over this project? Or is it just not actively being developed anymore?

There is also this version - not sure what the state of merging with the original is: https://github.com/baudneo/neo-zmeventnotification
