zerolxf commented on issue #13381: [Feature Request] Support CSRNDArray in kv_store
URL: https://github.com/apache/incubator-mxnet/issues/13381#issuecomment-442450342
 
 
   I want to implement the optimizer described in the paper "Sparse Communication for Distributed Gradient Descent" , available at https://arxiv.org/abs/1704.05021
   
   I tried to modify the value of NDArray directly through index, but it was a bit slow.
