zerolxf opened a new issue #13381: [Feature Request] Support CSRNDArray in kv_store
URL: https://github.com/apache/incubator-mxnet/issues/13381
 
 
   
   ## Description
   In distributed training, communication takes up a lot of time. In order to compress the communication time, an optimization method is to make the gradient sparse.
   
   But for now kv_store doesn't support push CSRNDArray values.
   Although support for this feature may cause other problems, right?
   
   For example, for CSRNDArray format
   
   >The format is designed for 2D matrices with a large number of columns, and each row is sparse
