Hi, so I am trying to load pretrained vgg19 in an interactive session within a GPU cluster. I get this permission error while trying the following:
Python 2.7.12 (default, Nov 19 2016, 06:48:10) 
[GCC 5.4.0 20160609] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import torchvision.models as models
>>> import torch
>>> vgg19 = models.vgg19(pretrained=True)
Downloading: "https://download.pytorch.org/models/vgg19-dcbb9e9d.pth" to /.torch/models/vgg19-dcbb9e9d.pth

    with open(dst, 'wb') as fdst:
IOError: [Errno 13] Permission denied: '/.torch/models/vgg19-dcbb9e9d.pth'

How can I possibly avoid this issue?
