Got it:  
Followed this [python - "Could not load dynamic library 'libcudnn.so.8'" when running tensorflow on ubuntu 20.04 - Stack Overflow](https://stackoverflow.com/questions/66977227/could-not-load-dynamic-library-libcudnn-so-8-when-running-tensorflow-on-ubun)  
Steps are:  
wget [https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86\_64/cuda-ubuntu2004.pin](https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64/cuda-ubuntu2004.pin)  
sudo mv cuda-ubuntu2004.pin /etc/apt/preferences.d/cuda-repository-pin-600  
sudo apt-key adv --fetch-keys [https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86\_64/${last\_public\_key}.pub](https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64/$%7Blast_public_key%7D.pub)  
or  
sudo apt-key adv --fetch-keys [https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86\_64/3bf863cc.pub](https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64/3bf863cc.pub) ← in my case  
sudo add-apt-repository “deb [Index of /compute/cuda/repos/ubuntu2004/x86\_64](https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64/) /”  
sudo apt-get update  
sudo apt-get install libcudnn8  
sudo apt-get install libcudnn8-dev
