Description
This PR adds support for building Phi-3 small ONNX models for CPU in the model builder.
Motivation and Context
Previously, the
SparseAttentionoperator was only supported on CUDA in ONNX Runtime. With the recent support forSparseAttentionon CPU, Phi-3 small ONNX models can now run on CPU. This PR also helps this issue.To use these changes, both ONNX Runtime and ONNX Runtime GenAI need to be built from source. Because the official PyTorch repo does not have a
tokenizer.jsonfile, thetokenizer.jsonfile needed for Phi-3 small in ONNX Runtime GenAI can be downloaded from the Hugging Face repos. Please see here for Phi-3 small 8K and here for Phi-3 small 128K.
