Direct Use

This is Microsoft Windows DirectML optimized model.<br> It might not be working in ONNX execution provider other than DmlExecutionProvider.<br> The needed python scripts are included in this repository

Prerequisites:<br>

1. Install Python 3.11 from Windows Store:<br> https://apps.microsoft.com/search/publisher?name=Python+Software+Foundation

2. Open command line cmd.exe

3. Create python virtual environment, activate the environment then install onnxruntime-genai-directml<br> mkdir c:\temp<br> cd c:\temp<br> python -m venv dmlgenai<br> dmlgenai\Scripts\activate.bat<br> pip install onnxruntime-genai-directml

4. Use the onnxgenairun.py to get chat interface.<br> It is modified version of "https://github.com/microsoft/onnxruntime-genai/blob/main/examples/python/phi3-qa.py".<br> The modification makes the text output changes to new line after "., :, and ;" to make the output easier to be read.

rem Change directory to where model and script files is stored<br> cd this_onnx_model_directory<br> python onnxgenairun.py --help<br> python onnxgenairun.py -m . -v -g

1. (Optional but recommended) Device specific optimization.<br> a. Open "dml-device-specific-optim.py" with text editor and change the file path accordingly.<br> b. Run the python script: python dml-device-specific-optim.py<br> c. Rename the original model.onnx to other file name and put and rename the optimized onnx file from step 5.b to model.onnx file.<br> d. Rerun step 4.

Speeds, Sizes, Times [optional]

15 token/s in Radeon 780M with 8GB pre-allocated RAM.<br> Increase to 16 token/s with device specific optimized model.onnx.<br> As comparison, LM Studio using GGUF INT4 model and VulkanML GPU acceleration runs at 13 token/s.

Hardware

AMD Ryzen Zen4 7840U with integrated Radeon 780M GPU<br> RAM 32GB<br>

Software

Microsoft DirectML on Windows 10
