【深度学习】OMP Error #15 Initializing libiomp5md.dll, but found libiomp5md.dll already initialized 报错提示完美解决方案
✨问题产生
重新安装了PyTorch CUDA后运行yolov5的train.py遇到如下报错
// 本次 opencv、torch、torchvision 都是通过whl文件安装的 可能会导致此问题问题
// 之前使用conda命令在线安装没有遇到这个问题
完整报错提示如下
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.

进程已结束,退出代码为 3
✨解决方案
解决方案一
import os
os.environ["KMP_DUPLICATE_LIB_OK"]="TRUE"
把如上代码加在代码最前面
//但是并不能从根本上解决问题
解决方案二
Everything 搜索 libiomp5md.dll
发现有Anaconda目录下存在两个libiomp5md.dll
C:\ProgramData\Anaconda3\envs\yolov5-3.1\Library\bin
C:\ProgramData\Anaconda3\envs\yolov5-3.1\Lib\site-packages\torch\lib
第一个路径是conda虚拟环境下的
第二个路径是torch下的
建议先备份路径
然后把第一个路径中的 libiomp5md.dll 剪切到其他地方问题完美解决
