This CL introduces an end-to-end Flax implementation of the DLRM-HSTU model, along with individual unit tests for the various components.

  • Converted all necessary PyTorch modules to Flax/Linen
  • Full training loop test for end to end model
  • Added unit tests for individual components (e.g. ActionEncoder, ContentEncoder, STU modules)
  • Ensured model runs correctly on TPUs.
  • Verified shape-correctness of all modules and parameters.
