How to input python-esque kwargs to a pytorch scripted c++ model

kwargs_pytorch.cpp

torch::jit::IValue myIvalue;
torch::jit::IValue myIvalue2;
torch::jit::script::Module module;

std::unordered_map<std::string, torch::jit::IValue> umap = {{"x", myIvalue}, {"opt", myIvalue2}};
auto result = module.get_method("forward")({}, umap);


// shows all potential arguments to model forward
std::cout << module.get_method("forward").function().getSchema().arguments() << std::endl;
