Stack "spotty-instance-tacotron-i1" was not created.

I try to run Tacotron example following the Medium article, but got an error

Creating IAM role for the instance...

Please, see CloudFormation logs for the details.

Where do I find CloudFormation logs?

I am using Windows 10 with Git bash (MinGW64).

And another question, I cloned the tacotron repo but needed to rename Dockerfile to Dockerfile.spotty. Why is it not named correctly in the repo? I worry if I do things correctly.

I found a closed issue with where to find CloudFormation logs, this is what I have there

I forgot to create requirements-spotty.txt (again I am puzzled why it is not in the docker directory already?), now it is a different error

There is no Spot capacity available that matches your request. 
(Service: AmazonEC2; Status Code: 500; Error Code: InsufficientInstanceCapacity)

and if I add onDemandInstance: true it is

You have requested more vCPU capacity than your current vCPU limit of 0 allows for the instance bucket that the specified instance type belongs to. 
Please visit http://aws.amazon.com/contact-us/ec2-request to request an adjustment to this limit. 
(Service: AmazonEC2; Status Code: 400; Error Code: VcpuLimitExceeded)

Not sure now I am on the right path, requesting limit adjustment seems incorrect here. Can you please help with what to do here?

The Rayhane-mamah/Tacotron-2 is not my repo and it doesn't contain changes that needed for training with Spotty. The point of that article was to show how to train an arbitrary model with Spotty.

There is no Spot capacity available that matches your request.

You can try to use another region where Spot instances are available. To check spot instance prices in particular regions, you can use the spotty aws spot-prices command:

$ spotty aws spot-prices -i p3.2xlarge -r eu-west-1
Getting spot instance prices for "p3.2xlarge"...

Price  Zone
0.9915 eu-west-1b
0.9915 eu-west-1c
3.3050 eu-west-1a

Apparently, new AWS accounts have very low limits for EC2 services. You can read how to increase them here: Amazon EC2 Service Limits .
