Tool to check if a ML model is compatible with the TOSA specification

Project description

TOSA Checker


The TOSA Checker is a tool that provides an easy way to ensure that a TensorFlow™ Lite model is compatible with the TOSA specification.

The project is currently in alpha, some stability issues may still be found.


To build the TOSA Checker the following are required:

  • Ubuntu® 20.04.03 LTS (the TOSA Checker has been tested on this OS, but should work on other Linux® OS)
  • Bazel™ (Bazelisk is an easy way to install the correct version of Bazel™)
  • Git™
  • Python® >=3.8 (python, python-dev and python-pip)

Building and installation

pip install -U pip setuptools wheel
pip install -U numpy GitPython
python bdist_wheel
pip install dist/<tosa_checker>.whl

Docker™ image

A Docker™ image to build the TOSA Checker is also provided. More information can be found on docker/


>>> import tosa_checker as tc
>>> checker = tc.TOSAChecker(model_path="model.tflite")
>>> checker.is_tosa_compatible()
