解决办法：

查看libgomp文件

root@bms-covacs:/usr/lib/aarch64-linux-gnu# ls  | grep libgomp
libgomp.so.1
libgomp.so.1.0.0

备份原本的

mv libgomp.so.1 libgomp.so.1.bak
mv libgomp.so.1.0.0 libgomp.so.1.0.0.bak

将报错中提示位置的libgomp软连接到该目录下即可解决问题

ln -s /usr/local/python3.9.18/lib/python3.9/site-packages/scikit_learn.libs/libgomp-d22c30c5.so.1.0.0 /usr/lib/aarch64-linux-gnu/libgomp.so.1
