CloudFormation GPUInstance Creation Error

[vrothenbergUCSD]

When launching the CDeep3m CloudFormation Create Stack process I run into the error:

API: ec2:RunInstances Not authorized for images: [ami-06908b4e4109c2c56]

I'm following this guide from the wiki:

https://github.com/CRBS/cdeep3m2/wiki/CDeep3M2-on-AWS-(via-Cloud-Formation-Template)

Not sure if the AMI is no longer available, or if I have misconfigured IAM settings.
