+This project is an alternative implementaion of [RFC:Standardizing composite ops in tensorflow to support efficient inference](https://github.com/tensorflow/community/blob/master/rfcs/20190610-standardizing-composite_ops.md).
+This project doesn't rely on the tracing functionality provided by `tf.function`
