Object-detection example: Logging stops after about 1 minute

[amararjun]

I am trying the object-detection on armv7hf camera. The output logging does not update after about 1 minute of execution. Is it the default behavior ? Is it possible to log output as long as the app is running ?
In the screenshot the application started at 17:45:14 and logging stops at 17:45:46

Hi @amararjun , I had a quick look in the source code of the main function in object detection and it should be this simple loop

while (true) {

that is continuously running and printing the two repeated log messages. I don't see any timeout specified in this loop.

I ran for almost ten minutes and stopped the application manually

Maybe you hit an error that didn't log?

Thank you for confirming the output.
Yes, the output of the model, the bounding boxes had negative values.
