I have two tensors in PyTorch:

tensor1 = torch.rand(4, 2)
tensor2 = torch.rand(10, 4)

I want to transpose the first one, to be able to then concatenate it to the second.

tensor1_t = torch.transpose(tensor1, 0, 1)

concat_tensor = torch.cat((tensor1_t, tensor2), dim=0)

assert concat_tensor.shape[0] == tensor1_t.shape[1] + tensor2.shape[0]
assert concat_tensor.shape[1] == tensor1_t.shape[0]

But doing like this gives me unspecified AssertionError. Can someone help me figure this out?
