what I did
Fixed a BUG that caused Error when training L2 and SSIM models
the Error is
RuntimeError: Expected 3D (unbatched) or 4D (batched) input to conv2d, but got input of size: [5]
my env
I deployed LPIPS on the latest version of pytorch (and other packages).And I met this BUG.So I'm not sure if this BUG exists on the deployment of the original version.
how did this BUG appear
The error report occurred after the model forward function, when the value was introduced into the rank model forward function. After debug, I found that, unlike the LPIPS model, the size of the forward output Tensor of these two models is [1], not expected [1,1,1,1].
Combined with the prompt of error report, I think this should be the key to solving BUG.I reshape the Tensor and it works now.
