URL: https://github.com/apache/incubator-mxnet/pull/15038#issuecomment-494754515
 
 
   I wrote a simple test to reproduce this issue. 
   ```
   #include <iostream>
   #include <vector>
   #include "mxnet-cpp/MxNetCpp.h"
   using namespace mxnet::cpp;
   
   enum TypeFlag {
     kFloat32 = 0,
     kInt8 = 1
   };
   
   int main(void){
       std::vector<mx_uint> shape{4, 5, 6};
       int src_dtype = kInt8;
       Context context = Context::cpu(); 
       // specify the data type according to the input NDArray
       NDArray src(shape, context, true, src_dtype);
       NDArray dst;
       dst = src.Copy(context);
       std::cout<<"src.dtype = "<<src.GetDType()<<std::endl;
       std::cout<<"dst.dtype = "<<dst.GetDType()<<std::endl;
       return 0;
   }
   ```
   Before 
   ```
   src.dtype = 1
   dst.dtype = 0
   ```
   
   After
   ```
   src.dtype = 1
   dst.dtype = 1
   ```
