安装tensorRT时，libcudnn.so.7: version `libcudnn.so.7' not found

Question

import tensorrt时ibcudnn.so.7' not found，然后我查看/usr/local/cuda-10.1/targets/x86_64-linux/lib/有8版本的，就进行软连接，之后出现下面的情况

>>> import tensorrt
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/chenyuping/.conda/envs/paddle/lib/python3.7/site-packages/tensorrt/__init__.py", line 1, in <module>
    from .tensorrt import *
