Draw high dimensional tensors as a matrix of matrices October 25, 2025
I have recently needed to draw the contents of high-dimensional (e.g., 4D and up) tensors where it is important to ensure that is clear how to identify each of the dimensions in the representation. Common strategies I’ve seen people do in this situation include printing a giant list 2D slices (what the default PyTorch printer will do) or flattening the Tensor in some way back down to a 2D tensor. However, if you have a lot of horizontal space, there is a strategy that I like that makes it easy to identify all the axes of the higher dimensional tensor: draw it as a matrix of matrices.
