带有OpenCV的libtorch：找不到版本GOMP_5.0

我正在尝试在同一项目中使用OpenCV和Libtorch。 libtorch已安装在/usr/include/libtorch中，从Pytorch网站下载。我正在使用CUDA 11.3的CXX11 ABI版本。

这是我的cmakelists.txt文件：

cmake_minimum_required(VERSION 3.23 FATAL_ERROR)
project(chess-rl VERSION 1.0)

find_package( OpenCV REQUIRED )

set(CMAKE_PREFIX_PATH /usr/include/libtorch/share/cmake/)

find_package(Torch REQUIRED)
include_directories(${OpenCV_INCLUDE_DIRS})
include_directories(${OpenCV_LIBS})
include_directories(${TORCH_INCLUDE_DIRS})
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${TORCH_CXX_FLAGS}")

file (GLOB SOURCE_FILES 
  ${PROJECT_SOURCE_DIR}/src/*.cc
  ${PROJECT_SOURCE_DIR}/src/chess/*.cc
)

add_executable(${PROJECT_NAME} ${SOURCE_FILES})
target_link_libraries(${PROJECT_NAME} ${OpenCV_LIBS} "${TORCH_LIBRARIES}" )
set_property(TARGET ${PROJECT_NAME} PROPERTY CXX_STANDARD 20)

该程序具有#include＆lt; opencv2/opencv.hpp＆gt;在顶部。编译工作正常，但是运行可执行文件给了我这个错误：

/usr/include/libtorch/lib/libgomp-52f2fd74.so.1: version `GOMP_5.0' not found (required by /usr/lib/libvtkCommonCore.so.1)

我相信Libtorch正在尝试使用与OpenCV不相容的库。如果我使用ld_preload =/usr/lib/libgomp.so./build/my-program运行程序，则运行良好。

如何在不使用该环境变量的情况下解决此错误？有没有办法将CMAKE中的特定库链接起来？

I'm trying to use OpenCV and LibTorch in the same project. Libtorch is installed in /usr/include/libtorch, downloaded from the PyTorch website. I'm using the cxx11 ABI version for CUDA 11.3.

Here's my CMakeLists.txt file:

cmake_minimum_required(VERSION 3.23 FATAL_ERROR)
project(chess-rl VERSION 1.0)

find_package( OpenCV REQUIRED )

set(CMAKE_PREFIX_PATH /usr/include/libtorch/share/cmake/)

find_package(Torch REQUIRED)
include_directories(${OpenCV_INCLUDE_DIRS})
include_directories(${OpenCV_LIBS})
include_directories(${TORCH_INCLUDE_DIRS})
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${TORCH_CXX_FLAGS}")

file (GLOB SOURCE_FILES 
  ${PROJECT_SOURCE_DIR}/src/*.cc
  ${PROJECT_SOURCE_DIR}/src/chess/*.cc
)

add_executable(${PROJECT_NAME} ${SOURCE_FILES})
target_link_libraries(${PROJECT_NAME} ${OpenCV_LIBS} "${TORCH_LIBRARIES}" )
set_property(TARGET ${PROJECT_NAME} PROPERTY CXX_STANDARD 20)

The program has a #include <opencv2/opencv.hpp> line at the top.
Compilation works fine, but running the executable gives me this error:

/usr/include/libtorch/lib/libgomp-52f2fd74.so.1: version `GOMP_5.0' not found (required by /usr/lib/libvtkCommonCore.so.1)

I believe libtorch is trying to use a library that is incompatible with OpenCV.
If I run the program with LD_PRELOAD=/usr/lib/libgomp.so ./build/my-program, it runs fine.

How can I fix this error without having to use that environment variable? Is there a way to link that particular library in CMake?

我遇到了同样的问题，您的线程为一个解决方案做出了贡献。
您需要在cmakelists.txt文件中添加共享库。

add_library(libName SHARED IMPORTED)
set_property(TARGET libName PROPERTY IMPORTED_LOCATION "/usr/lib/libgomp.so")
target_link_libraries(PROJECT_NAME
libName)

我希望我能帮助你
有善意的问候

I faced the same problem, and your thread contributed to one solution.
You need to add a shared library in your CMakelists.txt file.

add_library(libName SHARED IMPORTED)
set_property(TARGET libName PROPERTY IMPORTED_LOCATION "/usr/lib/libgomp.so")
target_link_libraries(PROJECT_NAME
libName)

I hope I could help you
With kind regards
