It's called named dimensions, named tensors, dimension tags: https://pytorch.org/docs/stable/named_tensor.html https://pytorch.org/docs/stable/named_tensor.html It's already there in PyTorch since a while (2019). However, as far as I know, it has not found too much adoption yet. In our framework RETURNN, we also make heavy use of dimension tags: https://returnn.readthedocs.io/en/latest/getting_started/data.html https://returnn.readthedocs.io/en/latest/getting_started/dat...
