marfago commented on issue #8849:   support monodimensional sparse array
URL: https://github.com/apache/incubator-mxnet/pull/8849#issuecomment-348414582
 
 
   @piiswrong now it is possible to create a dense vector as
   ```
   mx.nd.zeros(10, mx.cpu()) -> shape=(10,)
   ```
   
   but it is not possible to create a sparse vector like
   ```
   mx.nd.zeros(10, mx.cpu(), stype='csr') -> error
   ```
   
   I think there should be the same behavior between sparse and dense vector function/operators.
   In the case above it should be:
   ```
   mx.nd.zeros(10, mx.cpu(), stype='csr') -> shape=(10,)
   ```
   Moreover, operators that currently work with dense vector should work with sparse vectors in the same fashion.
