Example submission template

It would be great to have a minimal working example of MaskRCNNPredictor() or MMDetectionPredictor(), so that we can focus on building the network.

More masks than bboxes?

Some annotations appear to have more segmentation masks than bounding boxes. For instance the instance 66 of the train dataset has 2 masks, but only 1 bbox.

i = 66
xx = annotations["annotations"][i]['segmentation']
yy = annotations["annotations"][i]['bbox']
print(xx)
print(len(xx))
print(yy)
print(len(yy))
