Webtorch.cat(tensors, dim=0, *, out=None) → Tensor Concatenates the given sequence of seq tensors in the given dimension. All tensors must either have the same shape (except in the concatenating dimension) or be empty. torch.cat () can be seen as an inverse operation for torch.split () and torch.chunk (). WebPytorch provides the torch.cat () function to concatenate the tensor. It uses different types of parameters such as tensor, dimension, and out. Overview of PyTorch concatenate Concatenates the given arrangement of seq tensors in the given aspect.
