      | Args | 
     
     
      a | 
      SparseTensor, with indices sorted in row-major order. | 
     
     
      validate_indices | 
      Whether to validate the order and range of sparse indices in a. | 
     
    
   
   
  
   
    
     
     
    
    
     
      | Returns | 
     
     
      int32 Tensor of set sizes. For a ranked n, this is a Tensor with rank n-1, and the same 1st n-1 dimensions as a. Each value is the number of unique elements in the corresponding [0...n-1] dimension of a. |
