Hello,
Have been using PyTorch 0.2.0 for CNNs with no issues. Wonderful DL framework.
Conda unistalled PyTorch 0.2.0
Installed PyTorch 0.3.0 using
conda install pytorch torchvision -c pytorch
which installed
pytorch:     0.3.0-py36_cuda8.0.61_cudnn7.0.3h37a80b5_4 pytorch
torchvision: 0.2.0-py36h17b6947_1                       pytorch

First ran the trivial test program as for PyTorch 0.2.0
import torch


if __name__ == "__main__":

    x = torch.rand(5, 3)

    y = torch.rand(5, 3)

    if torch.cuda.is_available():
        x = x.cuda()
        y = y.cuda()
        x + y

    print('x', x)
    print('y', y)
    print('x + y', x + y)

The following error message was returned.

At a bit of a loss as to what this means and how to address it.

Any insight into this error message would be appreciated.
