The Keras nightly docker image sounds a good solution.
I will see if it works or not.


Yes, consider that also GPU and CPU images size diffs will make enough download impact when you will need to quickly open a Codespace or a Container to just contribute a PR.
Also `“postCreateCommand”: instead of using a final layer in the nightly image it will creare an overhead on every new container bootstrap also when the image is  already available on the host.
