'RoIAlignRotated' object has no attribute 'out_size'

[gys1287009045]

Modify the 101 line of rotate_single_level_roi_extractor.py:
out_size = self.roi_layers[0].out_size
to:
out_size = self.roi_layers[0].output_size[0]

Hi @gys1287009045
It is a bug that has been merged to the dev branch but still not merged to main branch #51
You could pull code from the dev branch and try again.
