问题描述：安装MMYOLO或者MMROTATE时，出现的问题：

看了一下系统支持的版本：

strings /lib/x86_64-linux-gnu/libc.so.6 | grep GLIBC_

在这里插入图片描述
最高支持2.3.0，然后去网上也没有搜到解决方案。再看一下问题，是mmcv/_ext.cpython-38-x86_64-linux-gnu.so这个动态库需要GLIBC_2.32，突然想起来，mmcv的动态库需要在新电脑上编译一下才行，这个动态库是从别处复制来的。

解决：
进入到mmcv文件夹，编译动态库：

# 我是直接去mmcv官网,releases找到自己想要的版本直接下载的
git clone -b 2.x git@github.com:open-mmlab/mmcv.git cd mmcvrm -r build && mkdir buildconda activate mmyolo# 安装 ninja 和 psutil 以加快编译速度
pip install -r requirements/optional.txt -i https://pypi.tuna.tsinghua.edu.cn/simple# 仅仅编译，不安装，过程较慢，建议关闭其他软件，卡死也没事，重新开机编译
MMCV_WITH_OPS=1 python setup.py build_ext --inplace# 建立软链接
cd ../mmyolo
ln -s ../mmcv/mmcv mmcv
