Awesome TFLite 
TensorFlow Lite (TFLite) is a set of tools that help convert and optimize TensorFlow models to run on mobile and edge devices - currently running on more than 3 billion devices! With TensorFlow 2.0, you can train a model with tf.Keras, easily convert it to TFLite and deploy it; or you can download a pretrained TFLite model from the model zoo.
This is a curated list of TFLite models with sample apps, model zoo, helpful tools and learning resources. The purpose of this repo is to -
- showcase what the community has built with TFLite
- put all the samples side-by-side for easy references
- knowledge sharing and learning for everyone
