OMP: Hint This means that multiple copies of the OpenMP runtime

安装paddle的时候，出现了如下错误：

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/.

网上解决方法：

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

但是治标不治本。
本问题出现主要是因为paddle包中包含了名为libiomp5md.dll的文件，与Anaconda环境中的同一个文件出现了某种冲突，所以需要删除一个。

在Anaconda文件夹下搜索，如下图，删除Anaconda包中libiomp5md.dll这个文件，即下图所选定的那个。

删除后再搜索

anaconda下面的libiomp5md.dll已经找不到。
