Mac OS “服务器似乎挂掉了，但是会立刻重启的”原因及解决

报错---- OMP: Error #15: Initializing libiomp5.dylib, but found libiomp5.dylib already initialized.

MAC 上运行到MTCNN相关代码时，jupyter notebook 就死掉

通过在terminal中查看日志：

8. Tune using inter_op_parallelism_threads for best performance.
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/.

Google上给的一个解决方法：

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

在jupyter notebook cell中添加以上代码即可解决。
