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

解决方法：

# 添加如下代码
import os
os.environ['KMP_DUPLICATE_LIB_OK'] = 'TRUE'
