Command Line Interface

New command line tools have been added and existing tools have been improved.

• olive --help works as expected.
• auto-opt:
  • The command chooses a set of passes compatible with the provided model type, precision and accelerator information.
  • New options to split a model, either using --num-splits or --cost-model.

Improvements

• ExtractAdapters:
  • Support lora adapter nodes in Stable Diffusion unet or text-embedding models.
  • Default initializers for quantized adapter to run the model without adapter inputs.
• GPTQ:
  • Avoid saving unused bias weights (all zeros).
  • Set use_exllama to False by default to allow exporting and fine-tuning external GPTQ checkpoints.
• AWQ: Patch autoawq to run quantization on newer transformers versions.
• Atomic SharedCache operations
• New CaptureSplitInfo and Split passes to split models into components. Number of splits can be user provided or inferred from a cost model.
• disable_search is deprecated from pass configuration in an olive workflow config.
• OrtSessionParamsTuning redone to use olive search features.
• OrtModelOptimizer renamed to OrtPeepholeOptimizer and some bug fixes.

Examples:

• Stable Diffusion: New MultiLora Example
• Phi3: New int quantization example using nvidia-modelopt
