Python 3.8 by default

[Guillem96]

Is there any specific reason why the default Python version is 3.7 while Python 3.8, or even 3.9 is completely mature>

Being honest it's a bit cumbersome to constantly downgrade my SageMaker training dependencies to meet the Python 3.7 requirements.

Thank you,

Per #113 (which was later merged into master) the source code is at 3.9, but the images from the default ECRs are not as mentioned there.

This change will make 3.8 default for 1.0: #118

It should be reflected in the default ECRs by 6/10.

Thanks!

I can’t see any new image in the ECRs for 5 weeks though… so not sure this should be closed.

[mabunday]

Which ECR are you looking at?

[lorenzwalthert]

AWS_DEFAULT_PROFILE=AnalysisSandbox aws ecr get-login-password --region eu-central-1 | docker login --username AWS --password-stdin 492215442770.dkr.ecr.eu-central-1.amazonaws.com
REPO="492215442770.dkr.ecr.eu-central-1.amazonaws.com/sagemaker-scikit-learn"
docker image ls $REPO

gives

I may be wrong, but I believe that command only lists local images that have already been pulled from that repository.

The Python 3.8 image was pushed on Jun 7th. Try pulling 492215442770.dkr.ecr.eu-central-1.amazonaws.com/sagemaker-scikit-learn:1.0-1-cpu-py3

docker image ls "492215442770.dkr.ecr.eu-central-1.amazonaws.com/sagemaker-scikit-learn"

[lorenzwalthert]

Right.. Thanks for the hint. I can confirm it has Python 3.8 now. Great. Our code base has Python 3.9 though... Are you planning to further bump Python after fixing #106?

[mabunday]

We don't currently have it on the roadmap, but yes once #106 is resolved I don't think there should be many blockers preventing us from bumping to 3.9 so I'd like to do that ASAP.
