Is the file format of NumCpp differs from numpy in python?

[yujincheng]

I dump the array in numpy use a.dump("test.bin"). Yet I can not recover the array in NumCpp with auto a = nc::load("test.bin") .
Is the file format of NumCpp differs from numpy in python?

Sorry for the confusion. No the file formats are not the same. NumPy uses pickle for its dump/save and load functions. NumCpp writes its arrays in a flat binary format. If you would like to read in a NumCpp dumped file with NumPy then you should use NumPy's fromfile function. eg.

#include "NumCpp.hpp"

int main()
{
    nc::NdArray<nc::int32> a = { {0, -1, -2}, {0, 1, 2}};
    a.dump("C:/Temp/test.bin");
    return 0;
}

Then from python

a = np.fromfile(r'C:\Temp\test.bin', dtype=np.int32).reshape([2,3])
