Missing average pool in modnets.vgg definition

[ankitk28]

I think vgg16 definition is missing average pool before classifier (I got error in weight copying step between pretrained vgg to modnets.vgg which I traced back to this )

Avg pool does not have any weights, so I am not sure what error you're getting.
The original VGG-16 definition does not have pooling as it only expects an input of size 224 x 224. If you are going to use a larger input, then you have to introduce an adaptive pooling of size 7x7 to match the expected output size of the last conv into fc6.

I guess AdaptiveAvgPool2d was not in the required versions:

torch==0.2.0.post3
torchvision==0.1.9;

it was newly added:
pytorch/vision#747

so I guess (with higher versions of pytorch) one can skip this when doing copy_.
