Hi again. After looking into the matter a little bit, I realise I'd have liked having the option of using a StoreManager ABC which I would implement myself using whatever storage provider I happen to use and whatever package versions happened to support it. To put it differently, instead of you implementing managers for gcs, azure, aws, etc, it would be a much nicer alternative (for me, and I suspect eventually for you too) for clearml's store manager to wrap whatever object the user provides, as long as it implements the necessary methods ( list , upload_file , download_file , download_folder , etc). I'd be happy to help with this.
