python -m pip install -r requirements.txt
pip install onnxruntime==1.18.0
pip install onnxruntime_extensions

1. Prepare the Whisper model

python prepare_whisper_configs.py --model_name openai/whisper-small --multilingual --enable_timestamps 

1. Run the Olive workflow to generate the optimized model

olive run --config whisper_cpu_int8.json --setup
olive run --config whisper_cpu_int8.json

1. The generated model will be in the \models\conversion-transformers_optimization-onnx_dynamic_quantization-insert_beam_search-prepost folder.
