Is there a lightweight image that I can use for a sagemaker processing job ?

Hi, for simple data processing you can likely use the SageMaker Scikit-learn image with SageMaker Processing, which is about 5.2GB (latest 1.2-1 image). Reference: https://docs.aws.amazon.com/sagemaker/latest/dg/pre-built-docker-containers-scikit-learn-spark.html

Alternatively, you can build your own custom container for SageMaker Processing, thus having flexibility in what to include in the image. Reference: https://docs.aws.amazon.com/sagemaker/latest/dg/build-your-own-processing-container.html
