Question regarding bbox_overlaps.py

[kartikJ-9]

I am trying to implement Cascade RPN with the most recent mmdetection. I have a custom dataset with 4 different id for detection. After running train.py script, after the 1st epoch I am getting the following error:

" File "/home/user/Downloads/mmdetection-master/mmdet/core/evaluation/bbox_overlaps.py", line 33, in bbox_overlaps
area2 = (bboxes2[:, 2] - bboxes2[:, 0] + 1) * (
IndexError: too many indices for array
"

Is it because I am using a CustomDataset? What changes I should do to make it work for my own dataset?

I have a epoch_1.pth file generated but I am not able to get mAP chart as expected for the detection task. I am new to this project and any help with this would be appreciated .Thanks.

I suggest running on COCO dataset first. If you can run COCO dataset normally, then you can change to your own dataset more easily.
