报错，信息如下：
OSError: [WinError 126] 找不到指定的模块。 Error loading "C:\Anaconda3\envs\python-3.11\Lib\site-packages\torch\lib\shm.dll" or one of its dependencies.
我的pytorch版本
pip install torch==2.3.0 torchvision==0.18.0 torchaudio==2.3.0 --index-url https://download.pytorch.org/whl/cu118
原因：mkl库以及intel-openmp库与pytorch版本不匹配，对于torch2.3.0版本要求mkl库版本符合如下要求：
mkl<=2021.4.0,>=2021.1.1 (from torch==2.3.0)
可能是由于之前别的任务需求中安装了最新版本的mkl库。
解决方法：
更新安装依赖
pip install torch==2.3.0 torchvision==0.18.0 torchaudio==2.3.0 --index-url https://download.pytorch.org/whl/cu118

可以看到对mkl库以及intel-openmp进行了重新安装！！！
intel-openmp 2023.2.0 >>> intel-openmp-2021.4.0
mkl 2023.2.0 >>> mkl-2021.4.0
