Easily Parse TFLite Models with Python
tflite package parses TensorFlow Lite (TFLite) models (
*.tflite), which are built by TFLite converter. For background, please refer to Introducing TFLite Parser Python Package.
pip install tensorflow==1.14.0 pip install tflite==1.14.0.post1
It would be better if use a correct version regarding tensorflow, where the mapping is as below.
.post[?] suffix is not needed, such that we can keep this version map simple.
If you notice that some version is missing, please consider contribute it! :)

Import the package
The package can be imported with easy import or original import, where the difference is how many
import you write - no functionality divergence. For supported interfaces, please refer to document page.
Easy Import (Recommanded)
Easy import enables parsing by one single
import tflite. This is achieved by importing classes and functions of one submodules into top module directly.
MobileNet parsing example shows how to parse model with
import tflite ONLY ONCE.
You can use this package just like the newly FlatBuffers generated one (example) to avoid any break of your legacy code.
from tflite.Model import Model
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 If you notice that the package is out of date, please feel free to contribute new versions.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.
- Fork the repository, and download it.
- Install additional depdendency via
pip install -r requirements.txt. And install flatbuffer compiler (you may need to manually build it).
- Generate the code for update. Tools have been prepared, there are prompt for actions.
schema.fbsfor a new version.
- Update the builtin operator mapping.
- Update the classes and functions import of submodules.
- Update the API document.
- Update the versioning in setup.py.
- Build and Test (simply
pytest) around. Don’t forget to re-install the newly built
tflitepackage before testing it.
- Push your change and open Pull Request.
- The maintainer will take the responsibility to upload change to PyPI when merged.
