C ++ Python converts data from vector to ndarray

I am creating a C ++ project that includes some python. I used to boost::python

, but now I'm stuck. I have some data stored in a std::vector

. The data needs to be sent to python in order to do some calculations. The Python NumPy functions I use need formatted data ndarray

, so I need a way to transform it. Since I want to do something else with the results in C ++, I want to convert the result back from ndarray

to std::vector

.

How to convert std::vector

to ndarray

and vice versa? Can anyone post some sample code? I know there is a lib called boost.numpy

, but are there any other ways because I was unable to build this library ...

Can I be used boost::python::numeric

for a job? Can anyone provide some sample code?

Is this possible without copying the data?
