💛 - Coveralls

[hodgestar]

@MrRobot2211 @jakelishman The self-host GPU runner appears to be working! Ready for review.

There is one minor issue I'm aware of -- coveralls is failing to find the git commit information to associate with the coverage upload. This happens because the NVidia AMI is based on Ubuntu 18.04 which comes with git 2.17. GitHub requires git >= 2.18 to do its fancy "single commit checkout" and falls back to creating just a tarball snapshot of the repository which doesn't contain the commit information.

We could try fix this in another PR by adding a step that does some version of:

sudo add-apt-repository ppa:git-core/ppa -y
sudo apt-get update
sudo apt-get install git -y
git --version

but I think that should either happen in another PR, or we should solve the issue by seeing if we can get an NVidia AMI based on Ubuntu 20.04.

@aktech Thanks for all your help. Looks like it's working nicely!

Do you perhaps know if there is an AMI we can use that gives us the NVidia drivers and Ubuntu 20.04?

This one seems to have what we need ami-0887cec38e5c0ab84

@MrRobot2211 The last test run seems to have the same git version issue as before. What is the AMI you've switched to and do you have a link to a description of what is in it?

Sorry for that.

The descriptio of this one is
Deep Learning AMI GPU CUDA 11.2.1 (Ubuntu 20.04) 20210625 - ami-0887cec38e5c0ab84
Built with NVIDIA CUDA, cuDNN, NCCL, GPU Driver, Docker, NVIDIA-Docker and EFA support. For a fully managed experience, check: https://aws.amazon.com/sagemaker
Root device type: ebs Virtualization type: hvm ENA Enabled: Yes

the links seem to be state-less so you will have to enter here

and then search ubuntu 20.04 nvidia. There are some more options but most of them come with some DL libraries pre-installed.

@MrRobot2211 Ah, that AMI is for us-east-2. I am trying the same AMI for eu-west-1.

[hodgestar]

@MrRobot2211 Nice! It looks like the eu-west-1 version of the AMI you suggested sorted the problem out. If you're happy with this PR now, I will merge it and we can start using it.

Nice one guys in finding out the right AMI for Ubuntu 20! I'll add it to the docs in here.
