How to transfer ownership of underlying data in py::array_t?

[vymao]

I have two questions. Say I create a py::array_t via an embedded Python interpreter action, like py::array_t<float> rdata = rdict.attr("get")("input_features");. Then:

1. Is the underlying data in an array_t stored on the stack or heap?
2. If it is on the heap, then I have data that is stored in an array_t that I would like to transfer the ownership of, in order to use in other places. I assume that once the actual array_t goes out of scope, it calls the destructor of this data, but I would like to preserve it out of scope. Is this possible?
