What does you known faces directory/content look like? That's what I'd check.

Only old pictures from the time before I upgrade to ubuntu 22.04

Make sure it’s structured per the docs. If it’s just a folder of pictures, that’s not right.

FIX!
After a while and some time for investigation I found the bug and here is the fix:
1. After a sudo -u www-data /var/lib/zmeventnotification/bin/zm_train_faces.py
Code: Select all
dtype=uint8), <_dlib_pybind11.full_object_detection object at 0x7fe95a72ce70>, 1
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "/var/lib/zmeventnotification/bin/zm_train_faces.py", line 33, in <module>
train.FaceTrain(options=g.config).train(size=args['size'])
File "/usr/local/lib/python3.10/dist-packages/pyzm/ml/face_train_dlib.py", line 130, in train
raise ValueError(
ValueError: Error opening known faces directory. Is the path correct?
2. Modify this script here -> /usr/local/lib/python3.10/dist-packages/pyzm/ml/face_train_dlib.py
3. Go to line 80 and replace
Code: Select all
known_face = known_face[:, :, ::-1]
with
Code: Select all
known_face = cv2.cvtColor(known_face, cv2.COLOR_BGR2RGB)
4. Modify this script here -> /usr/local/lib/python3.10/dist-packages/pyzm/ml/face_dlib.py
5. Go to line 182 and replace
with
Code: Select all
rgb_image = cv2.cvtColor(image, cv2.COLOR_BGR2RGB)

There may have been a typo on line 82 of face_train_dlib.py when the fixes were made. It should be cv2.COLOR_BGR2RGB.

FYI, this is still an issue and fixing the typo solves it.

Current version has the typo applied. Was committed on July 9th.

Can you clarify what you mean by current version? I was running ZM 1.37.50 and had the typo. I just did an apt update and apt upgrade and it did update to a new sub-release of zm 1.37.50, but it made no changes to /usr/local/lib/python3.10/dist-packages/pyzm/ml/face_train_dlib.py
Am I missing something?
Thanks!

pyzm is packages separately from zoneminder. I doubt apt will pick up the changes (perhaps we should package it for apt, I'll look into that). You need to updateit with pip. Or pip3 .
sudo pip3 install pyzm --upgrade
Should get you 0.3.64
