Your code is running using an input of [1, 1, 200, 200]:
conv1 = nn.Conv2d(1, 64, (1, 200), (1, 1), (0, 0))
batchnorm1 = nn.BatchNorm2d(64)

h = torch.randn(1, 1, 200, 200)
h = F.relu(batchnorm1(conv1(h)))

Could you check, if you are using batchnorm1 somewhere else in your model?
Maybe you have a typo somewhere.
