This talks about the current state of sparse tensors in PyTorch. sparse tensor in Compressed Sparse format - CSR, This means the algorithm is only implemented for C-arrays and hence is only available for PyTorch CPU tensors. Sparse tensors are used extensively in encoding schemes like TF-IDF as part of data pre-processing in NLP applications and for pre-processing images with a lot of dark pixels in computer vision applications. Can anyone just give me a hint how to do that?
