leleamol commented on issue #12869: Python trained model gives different features set in C++ URL: https://github.com/apache/incubator-mxnet/issues/12869#issuecomment-434870012 @MyraBaba According to the [ndarray.h](https://github.com/apache/incubator-mxnet/blob/master/cpp-package/include/mxnet-cpp/ndarray.h), the NDArray does support "-" and "*" operators with which you can "numpy.square(descA512- descB512)" operations. However, numpy.sum equivalent operation is not yet supported for NDArray.
