## What it is
A Python library that converts TensorFlow 1 frozen graph models (.pb) into Apple CoreML format for deployment on iOS devices. It is no longer maintained and has been superseded by the TensorFlow converter in Apple's coremltools package.

## Use cases
- convert a frozen TensorFlow 1 graph_def to CoreML format
- deploy TensorFlow models on iOS 12 or earlier
- run TensorFlow neural networks natively on Apple devices
- migrate legacy TF1 .pb models to CoreML

## When to choose
- your deployment target is iOS 12 or earlier
- your source model is a TensorFlow 1 graph_def serialized as a frozen protobuf
- you cannot use coremltools 4.0+ for a legacy model

## When to avoid
- you are targeting iOS 13 or later - use coremltools instead
- your model is TensorFlow 2.x or a SavedModel
- you need ongoing bug fixes or community support
- you are starting a new project

## Facets
- artifact type: library
- maturity: abandoned
- function: machine-learning, compiler
- domain: machine-learning, developer-tools
