环境：win10
工具：pycharm
运行yolov11的测试时报错：找不到site-packages\torch\lib\shm.dll" or one of its dependencies
本来顺着这个问题发现都让重新装pytorch，找到下载链接
download.pytorch.org/whl/torch_stable.html，打开就一堆，百思不得其舒服解
并且我懒，so......faint......我不打算这么做。
于是改换思路，单独启动torch，import torch，发现依旧报错
但错误变成了：OMP: Error #15: Initializing libomp.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://openmp.llvm.org/

本问题出现主要是因为pytorch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。
删除多余的dll文件，我的文件是env下的虚拟环境的文件。发现有时候见山不是山，希望能帮助一些人。
