How to convert void * to certainly type in python side?

[xiguadong]

Hi:
in c side , the code:

py::class_<tensor>(m, "Tensor")
        .def_readwrite("index", &tensor::index)
        .def_readwrite("type", &tensor::type)
        .def_readwrite("format", &tensor::format)
m.def("get_input_tensor", &get_input_tensor, "Get tensor handle .");

I call the get_input_tensor function in the python side, and then got a pointer . So ,how can I get the Tensor info from the pointer in the python side?

Thanks.
