[dependabot]

Updates the requirements on ray[default] to permit the latest version.

Release notes

Sourced from ray[default]'s releases.

Ray-2.50.0

Release Highlights

Ray Data: This release offers many updates to Ray Data, including:

• The default shuffle strategy is now changed from sort-based to hash-based. This will result in much lower peak memory usage and improved shuffle performance for aggregations.
• We’ve added a new expression API enables predicate-based filtering, UDF transformations with with_column, and column aliasing for more powerful data transformations
• Ray Data LLM has a number of new enhancements for multimodal data pipelines, including multi-node tensor and pipeline parallelism support per replica and ability to share vLLM engines across processors.

Ray Core:

Alpha release of Ray Direct Transport (formerly GPU objects) - simply enable it by adding the tensor_transport parameter to the existing native Ray Core API. This keeps GPU data in GPU memory until a transfer is needed, avoiding expensive serialization and copies to and from the Ray object store. It uses efficient data transports such as collective communication libraries (GLOO or NCCL) or point-to-point RDMA (via NVIDIA’s NIXL) to transfer data directly between devices, including both CPUs and GPUs.

Ray Train:

Local mode support for multi-process training with torchrun, enhanced checkpoint management with new upload modes and validation functions

Ray Serve:

• Async Inference alpha release - New Ray Serve APIs for supporting long-running asynchronous inference tasks, such as for video or large document processing. Includes capabilities for using different message brokers, adapters like celery and DLQ.
• Support for replica ranks - Replica level ranks are added for supporting large-model inference use-cases such as wide Data Parallel and Expert Parallel setups.
• FastAPI factory pattern support - Enables using FastAPI plugins that are not serializable via cloudpickle.
• Throughput optimizations - Enable these using the RAY_SERVE_THROUGHPUT_OPTIMIZED environment variable.

RLLib: Add StepFailedRecreateEnv exception for users with unsatisfiable environments

Ray Serve/Data LLM:

Improvements to multi node serving, loading models from remote storages, and sharing resources for efficiency (fractional gpus, sharing gpus on a data pipeline with shared stages)
