Hi,
I have started with my OAK-D on Mac
First, I was following the instructions and have got the demo script working. BUT, only for the color camera, no depth was available. I was trying to solve this issue, not sure what I have done, but now it shows me "X_LINK_DEVICE_NOT_FOUND" error and not working at all.
I can see the USB device is connected:
But the script is not working:
Ok. As usual, I was too fast writing the post.
The problem was with the device boot. I have plugged and connected again the power with USB not disconnected and this somehow made the device behave wrong.
What helped:
BUT! The stereo is still not working. I am getting this again:
So, help is still required
Hello Val, thanks for circling back with the solution to your issue!
We apologize for your depth issue, we have had similar occurrence at another user where one of the mono camera was disconnected (or not connected properly), resulting in OAK-D not being able to perform disparity depth. Note that we do test all our hardware before sending it out to our users so this could only happen during shipment.
Could you try running this example code and posting the output? It should print out all connected cameras. Also if both mono (left,right) cameras are detected, could you also try running both mono cameras and check if they output mono frames as expected?
Thanks, Erik
And this is an output from another script:
[14442C10A19060D700] [57.915] [system] [error] Attempted to start Mono Left camera - NOT detected!
So, looks like you are right and it is a hardware problem. I have received the package with no issues. No signs of damage on the box or on the device.
Hello Val, sorry again for the inconvenience. I believe you could try reconnecting the left camera to the board (first opening up the enclosure). I just asked the team internally if this should be the way to go (to not mess with the calibration of the mono cameras) and I will circle back with the suggested action to fix this.
Thanks, Erik
Hello @Val, could please you email us your shipping details to support@luxonis.com so we can send you a new OAK-D (with no expense to you)? We believe this would be the best action to solve the issue.
Thanks, Erik
I think installing depthai_experiments causes something similar too. (Or maybe the requirements for a single experiment.)
Here's the output trying to run depthai_hand_tracker after installing depthai_experiments:

Hi, @eric-soderberg
I'm working on project where im using the tracker and i keep seeing this mistake everytime i try to reload demo.py

Can u help me with this issue?
Thank you,

Oh, and when i try to tru comm with "python/python3" it's not working. Using "py" is working
geaxgx/depthai_hand_tracker.git
this is the tracker, and my camera is OAK-D-Pro
