Hi all,
I try to load a torchscript model in C++, but got an error:
The input data is actually double type. I tried to use
.double() following here but cannot run make.My code:
#include <torch/script.h> // One-stop header.
#include <iostream>
#include <memory>
int main(int argc, const char* argv[]) {
std::vector<double> inputdata({ 1.0, 2.0, 3.0, 4.0, 5.0 });
std::cout << inputdata << std::endl;
auto opts = torch::TensorOptions().dtype(torch::kDouble);
torch::Tensor input = torch::from_blob(inputdata.data(), {1, (int)inputdata.size()}, opts).to(torch::kDouble);
std::cout << input << std::endl;
if (argc != 2) {
std::cerr << "usage: example-app <path-to-exported-script-module>\n";
return -1;
}
torch::jit::script::Module module;
try {
// Deserialize the ScriptModule from a file using torch::jit::load().
module = torch::jit::load(argv[1]);
}
catch (const c10::Error& e) {
std::cerr << "error loading the model\n";
return -1;
}
std::cout << "ok" << std::endl;
std::vector<torch::jit::IValue> input_invar;
input_invar.push_back(input);
std::cout << "run forward" << std::endl;
at::Tensor output = module.forward(input_invar).toTensor();
std::vector<double> out_vect(output.data_ptr<double>(), output.data_ptr<double>() + output.numel());
std::cout << out_vect << std::endl;
}
Could you give me some suggestions, please ?
Best.
