Currently running into an issue:
Cluster startup Failed. Error: RuntimeError: botocore.exceptions.ClientError: An error occurred (InvalidBlockDeviceMapping) when calling the RunInstances operation: Volume of size 202GB is smaller than snapshot 'snap-02c4e6a0ad06cf3d6', expect size >= 400GB
Uses the new AIR Train API for examples and tests.
The `Result` object gets a new attribute - `log_dir`, pointing to the Trial's `logdir` allowing users to access tensorboard logs and artifacts of other loggers.
This PR only deals with "low hanging fruit" - tests that need substantial rewriting or Train user guide are not touched. Those will be updated in followup PRs.
Tests and examples that concern deprecated features or which are duplicated in AIR have been removed or disabled.
Requires https://github.com/ray-project/ray/pull/25943 to be merged in first
Ray SGD v1 has been denoted as a deprecated API for a while. This PR fully deprecates Ray SGD v1. An error will be raised if ray.util.sgd package is attempted to be imported.
Closes#16435
