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

在windows系统上的conda环境运行代码出现bug：

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.

查询的解决办法：
①有说把conda环境 anaconda/Library/bin 下自带的 libiomp5md.dll 文件删除，我直接去了我的conda环境下，发现该位置并没有 libiomp5md.dll 文件。

②我的办法，去我创建的虚拟环境下 anaconda/envs/env_name/Library/bin 的 libiomp5md.dll 文件删除，再跑代码就没问题了。
