Jul 2, 2026: Snowflake Container Runtime version 2.7

Snowflake Container Runtime CPU and GPU version 2.7 is now available. This release includes the following changes:

  • Added support for ipywidgets in notebooks.
  • The PyTorch backend now defaults to Ray Train. To opt out, set PYTORCH_USE_LEGACY_TRAINER=1. The legacy path will be removed in an upcoming release.
  • TunerConfig now defaults resource_per_trial to {"CPU": 1} when uses_snowflake_trainer=True.
  • Fixed an issue where get_session() could overwrite the notebook database and schema context.
