Purpose

  • Add vLLM 0.20.2

Toggle if you are merging into master Branch

By default, docker image builds and tests are disabled. Two ways to run builds and tests:

  1. Using dlc_developer_config.toml
  2. Using this PR description (currently only supported for PyTorch, TensorFlow, vllm, and base images)
How to use the helper utility for updating dlc_developer_config.toml

Assuming your remote is called origin (you can find out more with git remote -v)...

  • Run default builds and tests for a particular buildspec - also commits and pushes changes to remote; Example:

python src/prepare_dlc_dev_environment.py -b </path/to/buildspec.yml> -cp origin

  • Enable specific tests for a buildspec or set of buildspecs - also commits and pushes changes to remote; Example:

python src/prepare_dlc_dev_environment.py -b </path/to/buildspec.yml> -t sanity_tests -cp origin

  • Restore TOML file when ready to merge

python src/prepare_dlc_dev_environment.py -rcp origin

NOTE: If you are creating a PR for a new framework version, please ensure success of the local, standard, rc, and efa sagemaker tests by updating the dlc_developer_config.toml file:

  • sagemaker_remote_tests = true
  • sagemaker_efa_tests = true
  • sagemaker_rc_tests = true
  • sagemaker_local_tests = true
How to use PR description Use the code block below to uncomment commands and run the PR CodeBuild jobs. There are two commands available:
  • # /buildspec <buildspec_path>
    • e.g.: # /buildspec pytorch/training/buildspec.yml
    • If this line is commented out, dlc_developer_config.toml will be used.
  • # /tests <test_list>
    • e.g.: # /tests sanity security ec2
    • If this line is commented out, it will run the default set of tests (same as the defaults in dlc_developer_config.toml): sanity, security, ec2, ecs, eks, sagemaker, sagemaker-local.
# /buildspec <buildspec_path>
# /tests <test_list>

Are we intentionally to remove sglang 0.5.10?

I thought we usually add a new release and delete an old release
