Revise Azure installation instructions

[LouiseABowler]

As @sgibson91 points out in #13, the installation instructions need a round of revisions to work with the updates to Azure's user interface.

(Apologies for the ton of comments!)

Line 80 in the "Install CUDA" section:

Once you have logged into the VM...

Can you give instructions on how to do that please? This may require giving instructions on how to set a username & password or an SSH key during the resource deployment. FYI, I did username & password.

[sgibson91]

I'm trying ssh sgibson91@<public-ip-of-resource> but getting the following error:

ssh: connect to host <public-ip-of-resource> port 22: Operation timed out

I'm going to delete the resource and build again to make sure I haven't done any copypasta mistakes.

[sgibson91]

Need to select "Allow selected ports" in the "INBOUND PORT RULES" section of "Basics" panel and then select "SSH (22)" from the drop-down menu.

[sgibson91]

I would delete the Click the "Next: Disks" instruction as you can select "Review + Create" immediately from the bottom of the "Basics" panel. Especially if the automatic configuration is fine, otherwise can be a bit confusing to click through.

https://github.com/kochkinaelena/branchLSTM/pull/14#issuecomment-485754548 solved https://github.com/kochkinaelena/branchLSTM/pull/14#issuecomment-485749099 so would strongly recommend including it in the instructions!

Is this normal output from THEANO_FLAGS='floatX=float32,device=gpu' python outer.py --search=True --ntrials=100 --hseed=1?:

Using gpu device 0: Tesla K80 (CNMeM is disabled, cuDNN not available)

(It's running so I guess so!)

Everything's going well so far so I'd say I've concluded my review 😄
