Solve /sbin/ldconfig.real: /usr/local/cuda-11.8/targets/x86_64-linux/lib/libcudnn_ops_infer.so.8 is not a symbolic link

I received this error when installing packages in Ubuntu 23.10. To solve this issue, you can fix the CUDNN installation steps

1. Check the ~/.bashrc

export PATH="/usr/local/cuda/bin:$PATH"
export LD_LIBRARY_PATH="/usr/local/cuda/lib64:$LD_LIBRARY_PATH"
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda-11.8/lib64/

2. Copy CUDNN the right way

sudo cp -av include/cudnn*.h /usr/local/cuda/include
sudo cp -av lib64/libcudnn* /usr/local/cuda/lib64
sudo chmod a+r /usr/local/cuda/include/cudnn*.h /usr/local/cuda/lib64/libcudnn*

This should fixed the not a symbolic link problems!
