tflite 1.14.0

A package to parse TFLite models (*.tflite)

The python package to parse TFLite models

TFLite models (*.tflite) are in FlatBuffers format. This tflite package is built to parse the TFLite models from the schema.fbs of TensorFlow.

Usage

Using this package, you can parse the TFLite models (*tflite) in Python. One target of this package is to let people use it as the one originally built from schema.fbs.

This package has been published on pypi.org, pip install tflite will install. Basically, the usage styles include:

• Easy import avoids too many imports per submodules (example): import tflite. This is also the recommanded way to use this package.
• Nested import tflite modules tflite.tflite as it is the originally built one (example): from tflite.tflite.Model import Model. This is as a workaround when encountering bug in easy import.

The easy import imports the classes and functions of one submodules into top module directly, e.g. import the {package}.{submodules}.{class or function} as {package}.{class or function}. For example, when building the Model object, tflite.Model.GetRootAsModel(buf, 0) should be used rather than tflite.Model.Model.GetRootAsModel(buf, 0). This should be much easy to use. Look into the tests for more examples.

The package is versioning mirrored to TensorFlow package, which means a tflite==1.14.0 is generated from tensorflow==1.14.0. Versions after 1.14.0 is maintained.

Besides, if you prefer the very original style of the FlatBuffers generated package, try this one.

Development

To develop this package, additional depdendency can be installed via pip install -r requirements.txt.

The tools directory holds some scripts to update the package to corresponding TensorFlow version. There are three steps currently:

1. Download the schema.fbs change of a version.
2. Update the classes and functions import of submodules.
3. Update the versioning in setup.py.
4. Build and Test around.
5. Upload the package to PyPI.

Features could be added to make the parsing easy in the future.

Don't forget to re-install the newly built tflite package before testing it. You may also try source tools/source-me.sh rather than the annoying build and install process in development.
