24.07.2021 · model = torchvision.models.detection.maskrcnn_resnet50_fpn(pretrained=True) Results are ok (better than I expected) but not great. I was hoping someone with experience with Faster/Mask RCNN would be able to point me in a proven direction for maximizing the performance of this library to datasets that look different from coco.

torchvision.models.detection.retinanet_resnet50_fpn (pretrained=False, progress=True, num_classes=91, pretrained_backbone=True, **kwargs) [source] ¶ Constructs a RetinaNet model with a ResNet-50-FPN backbone. The input to the model is expected to be a list of tensors, each of shape [C, H, W], one for each image, and should be in 0-1 range.
