May I ask how to bind std::vector<std::pair<int64_t, pybind11::bytes>> such type in pybind11.

[newprogrammer2022]

When working ,I encountered a problem that need to bind std::vector<std::pair<int64_t, pybind11::bytes>> such type in pybind11.

`PYBIND11_MAKE_OPAQUE(std::vector<std::pair<int64_t, pybind11::bytes>>);
namespace py = pybind11;
PYBIND11_MODULE(flow_loader, m) {
	py::class_<FlowLoader>(m, "FlowLoader")
		.def(py::init<>())
		//.def("load_flow", &FlowLoader::LoadFlow)
		.def("load_flowfile", &FlowLoader::_LoadFlow)
		.def("pybytes_to_string", &FlowLoader::py_bytes_to_string)
		.def("unpack_package_byte", &FlowLoader::unpack_package_byte)
		.def("unpack_package", &FlowLoader::unpack_package);
	py::bind_vector<std::vector<std::pair<int64_t, pybind11::bytes>>>(m, "VectorPair", py::module_local(true));
}` 

Code like this , but this build failed in VS.
Did I do something wrong? I use std c++20 and pybind11 2.11.1.
Looking forward to reply. Thanks

Try to use
PYBIND11_MAKE_OPAQUE(std::pair<int64_t, pybind11::bytes>);
PYBIND11_MAKE_OPAQUE(std::vector<std::pair<int64_t, pybind11::bytes>>);
