Hello,

I’ve tried to retrain the object detection model in AI Center but it always stops with an error.

I’ve followed this documentation: Object Detection

And used Imglbl to create the dataset.

Here’s the error message:

Does anyone know what do do?

Hi Guys,
I would like to apologize for the very late response. I will reach to the team to figure out what might be the issue here. If any other details appeared since you posted this, please let us know.

@AntonMcG - could you take a look at it?
