# Building Torch-TensorRT on Windows

Torch-TensorRT has community support for Windows platform using CMake

Prerequisite:

- Microsoft Visual Studio

- LibTorch

- TensorRT

- CUDA

- cuDNN

## Build configuration

- Open Microsoft Visual Studio

- Open Torch-TensorRT source code folder

- Open Manage configurations -> Edit JSON to open CMakeSettings.json file.

- Configure the CMake build configurations. Following is an example configuration:

    {
      "configurations": [
        {
          "name": "x64-Debug",
          "generator": "Ninja",
          "configurationType": "Debug",
          "inheritEnvironments": [ "msvc_x64_x64" ],
          "buildRoot": "${projectDir}\\out\\build\\${name}",
          "installRoot": "${projectDir}\\out\\install\\${name}",
          "cmakeCommandArgs": "-S . -B out",
          "buildCommandArgs": "cmake --build out",
          "ctestCommandArgs": "",
          "variables": [
            {
              "name": "CMAKE_MODULE_PATH",
              "value": "$PWD\cmake\Modules",
              "type": "FILEPATH"
            },
            {
              "name": "Torch_DIR",
              "value": "<Path to libtorch>\share\cmake\Torch",
              "type": "FILEPATH"
            },
            {
              "name": "TensorRT_ROOT",
              "value": "<Path to TensorRT directory>",
              "type": "FILEPATH"
            },
            {
              "name": "CMAKE_BUILD_TYPE",
              "value": "Release",
              "type": " STRING"
            }
          ]
        }
      ]
    }
