Analyzing tf.function to discover AutoGraph strengths and subtleties - part 3In this third and last part, we analyze what happens when tf.function is used to convert a function that contains complex Python constructs in its body. Should we design functions thinking about how they are going to be converted?
Analyzing tf.function to discover AutoGraph strengths and subtleties - part 2In part 1 we learned how to convert a 1.x code to its eager version, the eager version to its graph representation and faced the problems that arise when working with functions that create a state. In this second part, we’ll analyze what happens when instead of a tf.Variable we pass a tf.Tensor or a Python native type as input to a tf.function decorated function. Are we sure everything is going to be converted to the Graph representation we expect?
Analyzing tf.function to discover AutoGraph strengths and subtleties - part 1AutoGraph is one of the most exciting new features of Tensorflow 2.0: it allows transforming a subset of Python syntax into its portable, high-performance and language agnostic graph representation bridging the gap between Tensorflow 1.x and the 2.0 release based on eager execution. As often happens all that glitters is not gold: although powerful, AutoGraph hides some subtlety that is worth knowing; this article will guide you through them using an error-driven approach.
Tensorflow 2.0: Keras is not (yet) a simplified interface to TensorflowIn Tensorflow 2.0 Keras will be the default high-level API for building and training machine learning models, hence complete compatibility between a model defined using the old tf.layers and the new tf.keras.layers is expected. In version 2 of the popular machine learning framework the eager execution will be enabled by default although the static graph definition + session execution will be still supported. In this post, you'll see that the compatibility between a model defined using tf.layers and tf.keras.layers is not always guaranteed.
