What's new

Added 🎉

  • Added clipping fix to Optimizer class to make it work with FSDP no_shard and DDP.
  • Added tests to compare grad norm differences between torch optimizer and clipping and OLMo optimizer and clipping on both CPU and GPU.
  • Expose memmap dtype in data config
  • Added support for DDP training.
  • Added caching to disk of HF datasets used in downstream evals
  • Added FLOPs logging
  • Added configs for OLMo tiny set of models
  • Added configuration field optimizer.record_update_metrics, which defaults to False, but when set to True will trigger AdamW to collect the step size norm and absolute max for each parameter.
  • Added configuration field optimizer.selective_updates, which defaults to False, but when set to True will tell the optimizer to skip updating the parameter and state when the corresponding gradient is 0.
  • Added configuration field optimizer.record_update_metrics, which defaults to False, but when set to True will trigger AdamW to collect the step size norm and absolute max for each parameter.
  • Added olmo_data, a package holding data files like tokenizers.
  • Added ability to load tokenizers from olmo_data package data.

Changed ⚠️

  • Added original legacy unsharding implementation back, as the default. The new
    shared memory implementation can be used by passing use_legacy_shared_mem_impl to unshard.py.
  • Refactor weight initialization. IMPORTANT: this does not maintain backwards-compatibility with older configs; the jobs will still run, but may produce different outputs.
  • Changed the behavior of the Lion optimizer to only record the update cosine similarity when optimizer.record_update_metrics is True in order to be consistent with the API.
  • Added HF datasets into olmo_data, and changed downstream eval to load from the package.

Fixed ✅

  • Changed from ignored_index to ignore_index for cross_entropy_loss when flash-attn>=2.5.8.
  • Make hf_olmo support AutoModelForCasualLM and similar HF methods again.
