[DEBUG] Temporary fix for issue "'RoIAlignRotated' object has no attribute 'out_size'" #40

[DangChuong-DC]

Motivation

Debug for issue #40

Modification

Since RiRoIAlignRotated object does not have attribute output_size but out_size, and vice versa for other RoI in mmcv.
-> Check if object is RiRoIAlignRotated then get out_size attribute, if not get output_size

BC-breaking (Optional)

This change make code work without changing downstream repo (mmcv), however I think better to update downstream mmcv repo; specifically in https://github.com/open-mmlab/mmcv/blob/fd3a1a16ea1d0b3def8719816007a5d6fd6b432e/mmcv/ops/riroi_align_rotated.py#L121
=> self.out_size to self.output_size

Use cases (Optional)

If this PR is for debugging #40

Hi @DangChuong-DC
We intend to adopt your temporary solution. At the same time, we will also PR to mmcv to fix the inconsistency of variable names.
