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

python运行以下情况：
OMP: Error #15: Initializing libomp.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.

解决办法1：
进入Anacoda的envs目录下，在该文件夹下搜索libiomp5md.dll文件，如果存在两个，那么删除其中一个。

解决办法2：
在所写代码前加入这两句代码
import os
os.environ[‘KMP_DUPLICATE_LIB_OK’] = ‘True’
解决办法3：
受到库的影响，使用命令conda install nomkl 对该包进行安装，进行解决问题。

一般第一、第二种办法即可解决此问题。
