报错：

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. For
more information, please see

解决

按照提示，设置KMP_DUPLICATE_LIB_OK环境变量为True。

import os
os.environ['KMP_DUPLICATE_LIB_OK']='True'

或者设置用户变量：
