> For methods other than forward you have to explicitly get the method and run it. For this Module class M(nn.Module): @torch.jit.export def infer(self, x): return x + 10 torch.jit.script(M()).save("m.pt") You can run it in C++ with script::Module::get\_method int main() { auto module = torch::jit::load("m.pt"); auto result = module.get\_method("infer")({torch::ones({2, 2})}); std::cout \<\< result \<\< "\n"; } We have an open issue to improve our C++ documentation to make thi…
