"WebNov 8, 2024 · In PyTorch, you can add dimension to a tensor using the unsqueeze () function. This function adds a singleton dimension at a given position in the tensor. For example, if you have a tensor of size (3,4,5), you can add a dimension of size 1 at position 2 using unsqueeze (), which will result in a tensor of size (3,4,1,5). " - Pytorch tensor expand_dims
