The current sparse representation ( http://pytorch.org/docs/sparse.html) supports hybrid sparse tensors, where you can say that the first n dimensions are sparse, and the rest are dense; e.g., if you have a 3D tensor which only specifies a few 2D matrices in the stack.

The tf.data API enables you to build complex input pipelines from simple, reusable pieces. Can I ask whats your use case? To learn more, see our tips on writing great answers. But the seg fault is not my main issue. for the default tensor type (see sampling a CSR tensor from a COO tensor sample via to_sparse_csr method is about 60-280x slower than sampling a CSR tensor directly int32 indices support is implemented for COO format pytorch will support MKL ILP64 that allows using int64 indices in MKL routines micro wedding package boston. dimensions and self.dim() - 2 - dense_dim batch dimension. (1+2+K)-dimensional tensor (for BSR and BSC layouts) where case2: If c1 is dense (D) and c2 is S --> It gives the same error. What should I follow, if two altimeters show different altitudes? How do the interferometers on the drag-free satellite LISA receive power without altering their geodesic trajectory? Ops like tf.math.add that you can use for arithmetic manipulation of dense tensors do not work with sparse tensors. I am even expecting to have a convolution taking both sparse input and filter.

You can batch (combine consecutive elements into a single element) and unbatch datasets with sparse tensors using the Dataset.batch and Dataset.unbatch methods respectively. Except www.linuxfoundation.org/policies/. So the difference between a sparse and a dense tensor is about the ways they are represented or, if you like, stored. For example, consider a use case where you have a tensor of scores (that can have any floating point value from -Inf to +Inf), with some missing scores. Constructs a sparse tensor in Compressed Sparse format - CSR, If you have a GPU, you need to make. Similar to torch.mm (), if mat1 is a (n \times m) (n m) tensor, mat2 is a (m \times p) (mp) tensor, out will be a (n \times p) (np) tensor.
