No Images Match "pytorch-efa01"

[verbose-void]

Running the main script command:

python train.py

I get:

Exception are  [AssertionError('No images match pytorch-efa01 in us-west-2, check name and image permissions')]
Traceback (most recent call last):

I have set up the snapshots & created volumes from them using the scripts provided.

Is there an extra setup for using an image? I'm using zone us-west-2a, in your README you reference us-east-1, maybe this is the only region where the AMI you reference (pytorch-eaf01) exists?
