Parsing TensorFlow Lite Models (*.tflite) Easily

Project description

Easily Parse TFLite Models with Python

Build and Test

This tflite package parses TensorFlow Lite (TFLite) models (*.tflite), which are built by TFLite converter. For background, please refer to Introducing TFLite Parser Python Package.

Usage

Install the package and use it like what you build from the TensorFlow codebase. It's recommended to install the version that same as the TensorFlow that generates the TFLite model.

pip install tensorflow==2.3.0
pip install tflite==2.3.0

Enhanced API

The generated python package is friendly to use sometimes. We have introduce several enhancements:

  • Easy import: You don't need to import every classes and funtions in tflite (example), but instead with a sigle import tflite (example).
  • Builtin opcode helper: The opcode is encoded as digits which is hard to parse for human. Two APIs added to make it easy to use.

Compatibility Handling

TensorFlow sometimes leaves compability hanlding of the TFLite model to the users. As these are API breaking change that can be easily fixed, we do this in the tflite package.

Contributing Updates

As the operator definition may change across different TensorFlow versions, this package needs to be updated accordingly. If you notice that the package is out of date, please feel free to contribute new versions. This is pretty simple, instructions as below.

  1. Fork the repository, and download it.
  2. Install additional depdendency via pip install -r requirements.txt. And install flatbuffer compiler (you may need to manually build it).
  3. Generate the code for update. Tools have been prepared, there are prompt for actions.
    1. Download schema.fbs for a new version.
    2. Update the builtin operator mapping.
    3. Update the classes and functions import of submodules.
    4. Update the API document.
    5. Update the versioning in setup.py.
    6. Build and Test (simply pytest) around. Don't forget to re-install the newly built tflite package before testing it.
  4. Push your change and open Pull Request.
  5. The maintainer will take the responsibility to upload change to PyPI when merged.
