[stevensmile00119]

vgg16_reducedfc.pth is the pretrained weights, and you should use it to train your own weight.

The reason of this error is because of this line torch.nn.DataParallel(net) which cause state_dict is not the same.
To solve the problem, you could fix the loading part into net.vgg.load_state_dict(vgg_weights)

[jwchoi384]

Hello @ayennam,
As @ShadowTraveler said, vgg16_reducedfc.pth is pre-trained backbone weight, not the weight file of the model.
To get the COCO evaluation result, you need to use your own weight trained with the COCO dataset.
