How to run detection?

[mzeimet]

If I use the default config of the detector, no hand is detected but the landmarks are correct.

If I change the model.name to one of the pretrained detectors, e.g. FRCNNMobilenetV3LargeFPN and set model.pretrained to True, I get the following error:

RuntimeError: Error(s) in loading state_dict for FasterRCNN: size mismatch for roi_heads.box_predictor.cls_score.weight: copying a param with shape torch.Size([91, 1024]) from checkpoint, the shape in current model is torch.Size([19, 1024]). size mismatch for roi_heads.box_predictor.cls_score.bias: copying a param with shape torch.Size([91]) from checkpoint, the shape in current model is torch.Size([19]). size mismatch for roi_heads.box_predictor.bbox_pred.weight: copying a param with shape torch.Size([364, 1024]) from checkpoint, the shape in current model is torch.Size([76, 1024]). size mismatch for roi_heads.box_predictor.bbox_pred.bias: copying a param with shape torch.Size([364]) from checkpoint, the shape in current model is torch.Size([76]).
