ValueError: No proposal boxes available for one of the images during training

See original GitHub issue

❓ Questions and Help

In #169 the case is discussed where no annotations are available. During training on small objects it is quite frequent that the RPN does not generate any proposal, what can I do now?

Reducing NMS_THRESH and FG_IOU_THRESHOLD does not seem to help.

I have found the source of this problem. The proposals were cut away by keep_only_positive_boxes since my contiguous_id started from 0 instead of 1, while 0 should be kept for background.
