I know this repo is not maintained anymore, but I have a question and hope I could use some insights.
After a few modifications, I was able to run the code using Pytorch 1.1 + CUDA 11.1. I trained the network for 2500 iterations on a custom dataset consisting of a few dozen of images and tested it on a sample batch from the training set. The segmentation results are far less accurate compared to the original Mask-RCNN benchmark even the training loss values are somewhat identical in both training regimes:
The only warning I get during training rotated mask-rcnn is the following, which I have not been able to traceback completely:
/content/rotated/rotated_maskrcnn/maskrcnn_benchmark/structures/bounding_box.py:268: UserWarning: indexing with dtype torch.uint8 is now deprecated, please use a dtype torch.bool instead. (Triggered internally at ../aten/src/ATen/native/IndexingUtils.h:30.)
bbox = BoxList(self.bbox[item], self.size, self.mode)
Is the performance drop an expected behaviour when the network is trained for the same number of iterations as the original mask rcnn, or is it because of a bug in interpreting the bounding boxes caused by a different PyTorch version than that suggested in the repo?

Hi there,
