Args: my_tensor1: torch.Tensor my_tensor2: torch.Tensor Returns: output: torch.Tensor Concatenated tensor. If I understand correctly sum(tensor_list) will allocate and keep O(N) intermediate tensors (same with a for loop) where N is number of tensors, which can be quite large in the case of big DenseNet. I propose to maybe generalize torch.add to support more than two tensors as input.TLDR : use torch.sum instead of the built-in sum. Note that the built-in sum() behavior will more closely resemble torch.sum in the next release. Note also that masking via torch.uint8 Tensors is now deprecated, see the Deprecations section for more information.z_two = torch.cat((x, y), 2 We use the PyTorch concatenation function and we pass in the list of x and y PyTorch Tensors and we’re going to concatenate across the third dimension. Remember that Python is zero-based index so we pass in a 2 rather than a 3. Because x was 2x3x4 and y was 2x3x4, we should expect this PyTorch Tensor to be 2x3x8. Parameters • t - an N-dimensional Tensor • marginals - a list of N vectors (will be normalized if not summing to 1). If None (de-fault), uniform distributions are assumed for all variables.
