Python报错记录：OMP: Error #15: Initializing libiomp5.dylib, but found libiomp5.dylib already

出错详情

OMP: Error #15: Initializing libiomp5.dylib, but found libiomp5.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. For more information, please see http://www.intel.com/software/products/support/.

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

分析

libiomp5.dylib已经初始化，貌似用mac会出现这个问题。

解决方法

添加两行代码：允许创建libiomp5.dylib副本

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