OMP: Error #15: Initializing libiomp5md.dll, but found libiomp5md.dll already initialized.

问题描述

在新的环境中使用jupyterlab或者pycharm运行代码时出现 以下报错

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.

Process finished with exit code 3

解决方法

网上有很多帖子推荐添加代码，但是对我的错误不管用。

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

最后，博主是在anaconda的虚拟env(例如名为python_l)下：删除..\Anaconda3\envs\python_l\Library\bin\libiomp5md.dll
