I’m new here, please feel to make suggestions.
Looking for official object detector(s) implementation which works w/o compilation in latest stable Pytorch.
Few examples

MaskR-CNN (possibility to train without mask ground truth?)
Faster R-CNN
R-FCN
OR single stage detectors
YoloV3
SSD

Would require to ‘train’ and ‘infer’ on new datasets & classes.
It seems the https://github.com/facebookresearch/maskrcnn-benchmark 3 requires compilation (referred as installation) and works with Pytorch nightly.
