NOTE: This is for the latest drivers, cuda and cudnn versions available as of 11/2018. Change the version numbers & URL for future releases

0. Prerequisites

Drop to a tty shell, stop the display manager (sudo service lightdm stop ). Make sure no X server is running.
Uninstall & purge installed/previous nvidia drivers
- sudo apt purge nvidia*
- sudo apt autoremove
- sudo dpkg -P cuda-*<TAB>
Blacklist nouveau drivers if not already done

Sometimes git clone/pull using SSH keys would fail with the following message even when the SSH keypair is setup on the server:

Unable to negotiate with <GIT_SERVER_IP> port 22: no matching host key type found. Their offer: ssh-rsa
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

The resolution is to ask git to use the the following SSH options:

	lossScalar = 1 - reward; % This is loss of the chosen action
	lossVector = zeros(1,self.nbActions);
	lossVector(astAction) = lossScalar;
	self.timeStep=self.timeStep+1;
	%The weight update step below depends on the learning policy. This will probably be handled by the NN/RL-net
	self.weights=self.weights.(exp(-sqrt(log(self.numActions)/self.timeStep)lossVector))';

	def single_action_cost(self,y):
	index=numpy.nonzero(y)
	true_cost=y[index]
	y = self.output.copy()
	cost = T.scalar()
	y_update = (y, T.set_subtensor(y[index], cost))
	f = function([cost], updates=[y_update])
	f([true_cost])

	return (y-self.output)**2
