Describe the question

Hi, Dear.

I want to use AWS s3 bucket for working directory.

• Is it already implemented? (maybe not I guess)
• Any best practice?
• Can I override working directory behaviour?

Thanks!

Not yet.
Usually, MMClassification doesn't handle file io related functions, and we use the FileClient in mmcv to deal with different file backends. And the AWS backend support is still in progress, see open-mmlab/mmcv#1545.
Of course, you can also implement a data transform to load images from AWS, refers to LoadImageFromFile

Hi, we will migrate the implementation in open-mmlab/mmcv#1545 to MMEngine.
