How do I completely wipe Cuda and CudNN off my ubuntu 16.04?

Question

Removing nvidia cuda toolkit and installing new one

Followed everything from the above link but I still have cuda and cuda-9.1 folder in my /usr/local/ directory?

Answer 1

Try these commands if you haven't already

sudo apt-get --purge -y remove 'cuda*'
sudo apt-get --purge -y remove 'nvidia*

after this I ran the command below and it did the trick for me

sudo apt-get autoremove --purge cuda
