AttributeError: 'int' object has no attribute 'backward'

If you were using the nin_imagenet.pth (NIN) model, you either forgot to specify the layers to use with -content_layers -style_layers, or you used invalid layers. NIN has different layer names than the VGG models.

AssertionError:
The NVIDIA driver on your system is too old (found version 9000).
Please update your GPU driver by downloading and installing a new
version from the URL: http://www.nvidia.com/Download/index.aspx
Alternatively, go to: https://pytorch.org to install
a PyTorch version that has been compiled with your version
of the CUDA driver.
