I want to use an object detection model for some use case.
I started with the YOLOv3, because I need to be able to perform detection on multiple images in less than few seconds (Even if it is not for real-time / video).
So, I successfully loaded and generated predictions using a keras model with pretrained weights.
The problem is that the pre-trained weights for this model have been generated with the COCO dataset, which contains very few classes (80).
What really surprises me is that all the pre-trained weights I can found for this type of algorithms use the COCO dataset, and none of them use the Open Images Dataset V4 (which contains 600 classes).
Is there a reason for that ? And if there is not, is there a place where I can find such pre-trained weights ?
