starimpact opened a new issue #9304: FlatTo1D in copy Tensor is a problem!
URL: https://github.com/apache/incubator-mxnet/issues/9304
 
 
   
   in ndarray Copy function:
   ```
           mshadow::Copy(to->FlatTo1D<cpu, DType>(),
                         from.FlatTo1D<cpu, DType>());
   ```
   FlatTo1D will cause a ```int of Shape``` overflow problem. Because the Shape value type is ```index_t``` which range is on ```int```. Sometimes, we need to handle a very big data, which size will exceed the range of int. 
   So... I suggest the following code:
   ```
           mshadow::Copy(to->FlatTo2D<cpu, DType>(),
                         from.FlatTo2D<cpu, DType>());
   ```
   yes....just convert to 2D shape, we will be able to handle much bigger very big array data.
   
   how about it?
