导入tensorflow时出错。
我的环境
ubuntu 18.04桌面
nvidia图形驱动程序470.42.01
cuda 11.4
python 3.6.14（Python）
tensorflow gpu 1.12.0
cuda环境变量设置已完成（11.4），链接符号链接位于/usr/local/cuda处，来自/usr/local/cuda-11.4
（使用旧版本的原因是该项目的sdk是在过去编写的。）
在运行python后导入tensorflow时，会发生以下错误：

>>> import tensorflow

我安装了cuda 9.0来修复此错误。然而，7.0版也出现了同样的错误。
我需要安装我需要的所有cuda版本吗？或者有没有其他办法解决这个问题？
