arrow::py::import_pyarrow() 导致分段错误

Question

我正在尝试使用 arrow-cpp 构建一个表，然后将其传输回 python。

为了做到这一点，我需要事先调用 arrow::py::import_pyarrow() ，但这会导致 SEGFAULT。

谁能帮我找出我哪里做错了？

这是一个最小的例子

CMakeLists.txt

cmake_minimum_required(VERSION 3.20.0)
project(TEST)
set(CMAKE_CXX_STANDARD 17)
set(Python3_EXECUTABLE "/home/auderson/miniconda3/bin/python3.8")

list(APPEND CMAKE_PREFIX_PATH "/home/auderson/miniconda3/lib/cmake/arrow")
find_package(Arrow REQUIRED)
find_package(ArrowPython REQUIRED)
find_package(Python3 COMPONENTS Interpreter Development)


include_directories(.
        /home/auderson/miniconda3/lib/python3.8/site-packages/pyarrow/include
        ${Python3_INCLUDE_DIRS})

add_executable(TEST
        mini_t.cpp
        )

target_link_libraries(${PROJECT_NAME} PRIVATE arrow_shared)
target_link_libraries(${PROJECT_NAME} PRIVATE arrow_python_shared)
target_link_libraries(${PROJECT_NAME} PRIVATE ${Python3_LIBRARIES})

.cpp文件

#include "arrow/python/pyarrow.h"

int main() {
    return arrow::py::import_pyarrow();
}

输出（调试模式）

Signal: SIGSEGV (Segmentation fault)

Process finished with exit code 1

如果不在调试模式：

Process finished with exit code 139

箭头的其他功能工作得很好。

C++ 应用程序不会初始化 Python 解释器。下面是一个正确执行此操作的 C++ 可执行文件示例：
