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

搭建简单的UNet网络，运行predict程序时，突然报错：

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 http://www.intel.com/software/products/support/.

第一次遇见该错误，网上查找相关解决方案：

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

添加代码，运行之后，仍然报错，仔细阅读错误信息：

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

意思是libiomp5md.dll已经初始化，那么可能是环境中dll文件冲突，找到运行环境目录，尝试删除libiomp5md.dll文件

再次运行程序，问题完美解决！
