Remove TH(CU)NN Sparse Linear (#17610)
Summary:
Sparse Linear in TH(CU)NN implements sparse linear layers without
using sparse matrices.
It is currently not documented in PyTorch and there is no functional or
module interface. This means it is unused from a PyTorch point of view.
The reason for removing it is twofold:
- The module uses sort, which I would like to move to ATen.
- When we implement a SparseLinear layer, we would want to do it
using sparse tensors, so it's not all that useful, anyway.
I checked this on slack with soumith, I hope the above is an accurate
representation. All bad ideas are my own.
This is part of the ongoing work to move
sort/topk/mode/median/kthvalue to ATen.
