Installation of libtorch: Follow the instructions on the official PyTorch website: https://pytorch.org/cppdocs/installing.html. In this example, we select the GPU version of libtorch. Please modify the paths in the following part of CMakeList (examples/lunar_lander/CMakeList.txt):
# libtorch gpu set(CUDA_TOOLKIT_ROOT_DIR "path/to/cuda") find_package(CUDA REQUIRED) list(APPEND CMAKE_PREFIX_PATH "path/to/libtorch") find_package(Torch REQUIRED) set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${TORCH_CXX_FLAGS}") target_link_libraries(lunar_lander PRIVATE "${TORCH_LIBRARIES}") set_property(TARGET lunar_lander PROPERTY CXX_STANDARD 17) if (MSVC) file(GLOB TORCH_DLLS "${TORCH_INSTALL_PREFIX}/lib/*.dll") add_custom_command(TARGET example-app POST_BUILD COMMAND ${CMAKE_COMMAND} -E copy_if_different ${TORCH_DLLS} $<TARGET_FILE_DIR:example-app>) endif (MSVC)
