一、报错信息

        完整报错如下：

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/.

 

二、原因

        新建虚拟环境，然后运行程序时报错。上网查找原因是在虚拟环境下存在了两个libiomp5md.dll文件。一个是在pytorch包里的，而另一个是在虚拟环境所在目录的位置中。很奇怪这两个文件。

 

 

 

三、解决方法

        上网查看相关的文章博客，总结了两种方法。

        1）代码解决

                在报错的Python脚本中使用os模块，加入环境变量。代码如下：

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

 

        2）手动解决

                将已经存在的两个libiomp5md.dll删除一个（建议使用第一种方法，因为谁也不知道删完之后会不会影响别的包，进而引发其他错误）
