T5 model support

[ravindra-ut]

Hi,
Can you please provide the support for T5 model inference. I see that only decoder models are supported https://github.com/ray-project/aviary/tree/master/models/static_batching

Thanks

hi @ravindra-ut, I was able to deploy flan t5 xl on aviary with aviary v0.2.0 and the following model yaml. I ran using 1 a10 gpu

deployment_config:
  autoscaling_config:
    min_replicas: 1
    initial_replicas: 1
    max_replicas: 1
    target_num_ongoing_requests_per_replica: 64.0
    metrics_interval_s: 10.0
    look_back_period_s: 30.0
    smoothing_factor: 1.0
    downscale_delay_s: 300.0
    upscale_delay_s: 60.0
  max_concurrent_queries: 2000
  ray_actor_options:
    resources:
      accelerator_type_a10: 0.01

  model_init_kwargs:
    trust_remote_code: true
  scheduler:
    policy:
      max_batch_total_tokens: 4096
      max_batch_prefill_tokens: 2048

    generate_kwargs:

      temperature: 0.4
      top_p: 1.0

    prompt_format:

      trailing_assistant: ""
      user: "{instruction}"
      default_system_message: ""
    stopping_sequences: ["<unk>", "</s>"]
scaling_config:
  num_workers: 1

  num_cpus_per_worker: 8
  placement_strategy: "STRICT_PACK"
  resources_per_worker:
    accelerator_type_a10: 0.01

I'm going to close this for now since I don't think this is an issue any more, however please reopen if there are any other issues.

Could we please check this in to a repo as a supported LLM config?

Thanks @avnishn . Is the t5 supported with vLLM or TGI ?

[akshay-anyscale]

T5 is not supported with vLLM right now. We can pick this one when vLLM has support - vllm-project/vllm#187
