I have the following model:
model = torch.nn.Sequential(
torch.nn.Conv3d(1, 128, kernel_size=3, padding=1),
torch.nn.ReLU(),
torch.nn.Conv3d(128, 128, kernel_size=3, padding=1),
torch.nn.ReLU(),
torch.nn.Conv3d(128, 128, kernel_size=3, padding=1),
torch.nn.ReLU(),
torch.nn.Conv3d(128, 128, kernel_size=3, padding=1),
torch.nn.ReLU(),
torch.nn.Conv3d(128, 128, kernel_size=3, padding=1),
torch.nn.ReLU(),
torch.nn.Conv3d(128, 1, kernel_size=3, padding=1),
torch.nn.ReLU()
).to(device)
For which, I use batches of the size N x 160 x 256 x 256
I was running into the RuntimeError: CUDA out of memory
error so I reduced the batch size to 2, which resulted in this error instead:
RuntimeError: cuDNN error: CUDNN_STATUS_NOT_SUPPORTED. This error may appear if you passed in a non-contiguous input.
A quick search in google suggested that my batch size was still too large so I reduced it 1, which surprisingly gave me the RuntimeError: CUDA out of memory
error again.
How can I resolve this issue?
Thank you.
