Most ops on tf.sparse.SparseTensors treat missing values and explicit zero values identically. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide, If you get a segfault from PyTorch, you probably need to report a bug. It is possible to explicitly include zero values in the values of a COO sparse matrix, but these "explicit zeros" are generally not included when referring to nonzero values in a sparse tensor. You can also use tf.data.experimental.dense_to_sparse_batch to batch dataset elements of varying shapes into sparse tensors. Convert a tensor to compressed column storage (CSC) format. torch.sparse_csc, torch.sparse_bsr, or device will be Why and when to use sparsity By default PyTorch stores torch.Tensor stores elements contiguously physical memory. So I can use PyTorch in this case. Build datasets from sparse tensors using the same methods that are used to build them from tf.Tensors or NumPy arrays, such as tf.data.Dataset.from_tensor_slices. In particular, this allows for one way to encode missing/unknown data in your training data. The COO encoding for sparse tensors is comprised of: A nonzero value in the context of a tf.sparse.SparseTensor is a value that's not explicitly encoded. of the resulting BSR or BSC tensor.
