Torch 学习

1. 下载与安装：

https://pytorch.org/get-started/locally/

安装cuda9.2 & cudnn https://developer.nvidia.com/rdp/cudnn-download  

2.  第一个程序

　　编写CMakeLists.txt

cmake_minimum_required(VERSION 3.0.0 FATAL_ERROR)
project(simnet)

set(Torch_DIR "/opensource/libtorch/share/cmake/Torch")

find_package(Torch REQUIRED)

message(STATUS "Pytorch status:")
message(STATUS " libraries: ${TORCH_LIBRARIES}")

add_executable(simnet run2.cpp)
add_compile_options(-fpermissive)

target_link_libraries(simnet ${TORCH_LIBRARIES})
set_property(TARGET simnet PROPERTY CXX_STANDARD 14)

　　编写测试程序

#include <torch/script.h> // One-stop header.

#include <iostream>
#include <memory>

int main(int argc, const char* argv[]) {
  if (argc != 2) {
    std::cerr << "usage: example-app <path-to-exported-script-module>
";
    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
";
    return -1;
  }

  std::cout << "ok
";
}
 

mkdir build 

cmake .. 

make
