DepthAI V3 not working OAK-D Pro POE

JonasVorwerk

We can't get the camera working. Within PyCharm we create a new environment. Installed DepthAI using this guide: https://docs.luxonis.com/software-v3/depthai/

getting this error:

objc[1593]: Class CVWindow is implemented in both /Users/myuser/PycharmProjects/PythonProject/depthai-core/venv/lib/python3.13/site-packages/cv2/cv2.abi3.so (0x109c82628) and /Users/myuser/PycharmProjects/PythonProject/depthai-core/venv/lib/python3.13/site-packages/palace.dylibs/libdepthai-core.dylib (0x119c5d368). This may cause spurious casting failures and mysterious crashes. One of the duplicates must be removed or renamed.

Any tips how to solve this?

Hey @JonasVorwerk
For DepthAi we recommend python 3.10–3.12.
Could you try to create a new venv with python 3.10 and then folowing the guide.

Thanks,
Oskar

Thanks for your quick reply, unfortunately same messages:

some examples work, but I'm interested in the object_tracker.py example.

The depthai needs to be recompiled and configured without a duplicate CVSlider class.. It's our issue and we'll fix it. I am also running on Mac and haven't had issues with it yet. You can generally ignore it for now.

Thanks,
Jaka

JonasVorwerk

Running object_tracker.py nothing happens, no video, no popup…

JonasVorwerk
Shouldn't matter. Check your environment - you might have headless opencv installed.

Thanks,
Jaka

JonasVorwerk

I have opencv installed following to documentation on the depthAI site.

What is headless and how can tie she installed?

JonasVorwerk

We bought this camera and from day 1 we can't get the examples working and it's getting very frustrating since most of the time it's just not responding. Is there a way they someone helps us using a video call / screen sharing? Just to keep us going?

Sure thing. Please write to support@luxonis.com and we'll figure out a time.

Thanks,
