SSL Handshake Error when getting pretrained model #2271

Description

@petered

When I run the script,

import torchvision.models

vgg16 = torchvision.models.vgg16(pretrained=True)

I get a "sslv3 alert handshake failure".

Downloading: "https://download.pytorch.org/models/vgg16-397923af.pth" to /home/petered/.torch/models/vgg16-397923af.pth

Any idea what the problem is?
