这很奇怪。
我正在使用Cython构建包装外部库（mypackage）的Python程序包（我们称之为externallib）。 externallib用Fortran编写，但是有一个用C编写的接口库。我使用这个C接口库从Cython访问externallib。
直到我导入numpy或依赖于numpy的任何其他软件包（例如pint，matplotlib，{{ 1}}等）放入pandas模块（一个mypackage.core文件）中。我只导入这些软件包，甚至不使用它们。这会导致分割错误。
.pyx当我多次调用Current thread 0x00007f02925ee740 (most recent call first):
File "build/temp/mypackage/core_test.py", line 191 in _test_runner

../build/scripts/build-package-linux.sh: line 151: 22796 Segmentation fault (core dumped) python3 build/temp/mypackage/core_test.py
以提供计算输入数据后，在externallib中调用计算例程时，就会发生分段错误。
我知道numpy也是使用Fortran，C和Cython内置的。我应该寻找明显的东西来确保numpy与其他C / Fortran外部库之间的兼容性吗？造成细分错误的原因是什么？
感谢您的帮助。
