具体原因是安装cuda的时候，按照教程将cudnn也安装到了系统cuda路径中，然后在python虚拟环境中使用pip install torch时会自动安装一个cudnn，两个发生了冲突。
解决办法
首先激活虚拟环境，使用pip list查看：
里面确实安装了cudnn，解决办法也很简单，既然产生了冲突，要么把系统里面的cudnn去掉（不推荐，如果部署其他的如Tensor rt时会出现问题，反而更麻烦）。要么把虚拟环境中的cudnn去掉（推荐），所以只需要执行如下命令：
pip uninstall nvidia-cudnn-cu12本文参与 腾讯云自媒体同步曝光计划，分享自作者个人站点/博客。
