我想用pyByD11将C++函数绑定到Python。 C++函数返回:
auto tree_fusion_depth_map(const hg::tree & tree_1, const hg::tree & tree_2, const hg::tree & tree_3) {
//some code here
return xt::eval(xt::view(depth, xt::range(0, nleaves)));
在python中调用函数时,我得到:
TypeError: Unable to convert function return value to a Python type! The signature was
(arg0: higra.higram.Tree, arg1: higra.higram.Tree, arg2: higra.higram.Tree) -> xt::xtensor_container<xt::uvector<long, xsimd::aligned_allocator<long, 16ul> >, 1ul, (xt::layout_type)1, xt::xtensor_expression_tag>
这是C++代码中的Python模块和DOCTROM:
PYBIND11_MODULE(mbfusion, m)
{
xt::import_numpy();
m.doc() = R"pbdoc(
An example higra extension
)pbdoc";
m.def("function", function, "An example function.");
}
我如何解决这个问题
