ML SDK Model Converter

The ML SDK Model Converter is a command line application that translate TOSA ML Models to VGF files. A VGF file is a model file containing SPIR-V™ modules and constants that are required to execute the model through the ML extensions for Vulkan®. The ML SDK Model Converter supports several different TOSA encodings as inputs:

  • TOSA FlatBuffers

  • TOSA MLIR bytecode

  • TOSA MLIR textual format

The ML SDK Model Converter can also produce TOSA FlatBuffers from its input, without performing any conversion.

You can also use the ML SDK Model Converter to check that all tensors specified in the input model are ranked and have fixed, non-dynamic shapes. If a dynamic tensor is detected, the program will exit with an error.

The suggested workflow for this tool as part of the ML SDK for Vulkan® is:

  1. A TOSA MLIR file is converted to a VGF file using the ML SDK Model Converter (this project).

  2. The generated VGF file and VGF library VGF Dump Tool is used to create a JSON scenario template file. The template file is edited with the correct filenames and paths.

  3. Using the generated VGF file and scenario file, the ML SDK Scenario Runner then dispatches the contained SPIR-V™ modules to the ML extensions for Vulkan®.
