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? @piiswrong
