instance segmentation test does not work with "--show"

[betogulliver]

Thanks for sharing your research/code with us. Much appreciated.

I tried to run the "instance segmentation" test with "--show" but it fails on my setup (see below for details).
"instance segmentaion" test with "--eval segm" works OK though.
Any ideas?

python tools/test.py configs/D2Det/D2Det_instance_r101_fpn_2x.py      checkpoints/D2Det-instance-res101.pth      --show

  File ".../code/01-D2Det/mmdet/models/detectors/base.py", line 178, in show_result
    img_show[mask] = img_show[mask] * 0.5 + color_mask * 0.5
IndexError: boolean index did not match indexed array along dimension 0; dimension is 800 but corresponding boolean dimension is 427

Hi. I show results using detectron2, instead of mmdetection. Your problem may be fixed by changing following files:
