Re: Install fails for ObjectDetectionCoral 2.1.4

I'll need more info, but am I right in assuming Coral.AI using USB on Windows?

"unable to create interpter" is something I see often in this setup. For me, I either unplug the USB and try a different port, or restart the Coral module itself. It's very finicky unfortunately.

cheers

Thanks for the reply Chris,

Yes the coral stick is connected via USB. After re-installing the module a number of times I have managed to get the install to complete without the error in the first code block, however in all cases I still receive the errors in the second and third code block (the last code block is from Agent itself when it tries to call the object detection).

For now I have rolled back to CPAI beta 2.1.11 as this works flawlessly with my coral stick.

HI Everyone, trying to get CPAI setup to read license plates in blue iris. I have tried installing and reinstalling the module a few times, and the same error keeps happening below with the ALPR module every time I run it. Any ideas on why this may be happening>

I am using the following versions
CPAI Version: 2.5.4
Object Detection (YOLOv5 6.2) 1.9.1
License Plate Reader 3.0.2

ALPR 2.5 Not Working -- Try this workaround

Hi there,
I have an ongoing issue after updating to ALPR 2.5. I have re-installed a few times but continue to receive the below error and ALPR fails to detect plate numbers in Agent 5.3. Not sure if there is any particular fix or if it's possible to roll back to the previous version?

Many thanks for any suggestions.

You are on an old version of the ALPR module. Try update CodeProject.AI. The current version of CodeProject.AI has version 3.0.2 of the ALPR module.

I have noticed a runtime error two times. No major problems and the system keeps running just fine.
Just thought I would post the traceback as feedback for the developers.

I have 2 Blueiris installations with CodeProject running on each Blueiris server both servers are now on Blueiris 5.8.7.9. With CodeProject 5.2.1 things worked mostly fine, but when I upgraded to 5.2.4 I started getting the error below and AI_Timeout 500 errors in Blueiris. I was hoping upgrading to 5.2.5 would fix it, but as well know now that version had issues. so I went to 5.2.6 but I am still having the same issue.
