Loading pre-trained resnet50

[thom966]

I have a question regarding loading a ResNet model other than ResNet-34. I tried to use ResNet-50 with the pre-trained weights provided by PyTorch, but the ResNet-50 model generated from class ResNetBackbone(Backbone) is different from the pre-trained model from PyTorch.

Loaded pre-trained model from pytorch:

From class ResNetBackbone(Backbone):

Could you please tell me how to properly load the pre-trained ResNet-50? Thank you so much.

Pretrained weights from PyTorch are loaded automatically for ResNet50 unless you pass the '--no-pretrained-backbone' argument to main.py (see HERE).

Loading is done HERE. However, note that the weights are from torchvision v0.4.2 (see HERE), keys in newer versions may be different.
