在使用pytorch运行一个小案例时，绘制图像时出现了

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.

OMP:错误#15:正在初始化libomp5md.dll，但发现libomp5mD.dll已初始化。

OMP：提示这意味着OpenMP运行时的多个副本已链接到程序中。这是危险的，因为它可能会降低性能或导致不正确的结果。最好的做法是确保只有一个OpenMP运行时链接到进程中，例如避免在任何库中静态链接OpenMP运行库。作为一种不安全、不受支持、未记录的解决方法，您可以将环境变量KMP_DUPLICATE_LIB_OK=TRUE设置为允许程序继续执行，但这可能会导致崩溃或无声地产生不正确的结果。有关更多信息，请参阅http://www.intel.com/software/products/support/.

解决：在代码中加入以下两行解决

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