MacOS OMP: Error #15: Initializing libiomp5.dylib, but found libomp.dylib already initialized

OMP: Error #15: Initializing libiomp5.dylib, but found libomp.dylib 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.

Process finished with exit code 134 (interrupted by signal 6: SIGABRT)

Abort trap: 6

解决方法一：

import os
os.environ["KMP_DUPLICATE_LIB_OK"] = "TRUE"

解决方法二：

# 在命令行执行，test.py就是你的python code
KMP_DUPLICATE_LIB_OK=TRUE python test.py
