OMP: Error #15: Initializing libiomp5md.dll, but found libiomp5md.dll already initialized. OMP: Hint This means that multiple copies of the OpenMP runtime have been linked into the program. That is dangerous, since it can degrade performance or cause incorrect results. The best thing to do is to ensure that only a single OpenMP runtime is linked into the process, e.g. by avoiding static linking of the OpenMP runtime in any library. As an unsafe, unsupported, undocumented workaround you can set the environment variable KMP_DUPLICATE_LIB_OK=TRUE to allow the program to continue to execute, but that may cause crashes or silently produce incorrect results.

这个错误是由于程序中链接了多个OpenMP运行时库导致的。这可能会降低性能或导致错误的结果。

解决这个问题的最好方法是确保只链接一个OpenMP运行时库，比如避免在任何库中静态链接OpenMP运行时库。

如果你想要一个不安全、不支持、不文档化的解决方法，你可以设置环境变量 `KMP_DUPLICATE_LIB_OK=TRUE`，这样程序可以继续执行，但可能会导致崩溃或产生错误的结果。
