Mixed precision is the use of both 16-bit and 32-bit floating-point types in a model during training to make it run faster and use less memory. By keeping certain parts of the model in the 32-bit types for numeric stability, the model will have a lower step time and train equally as well in terms of the evaluation … See more While mixed precision will run on most hardware, it will only speed up models on recent NVIDIA GPUs and Cloud TPUs. NVIDIA GPUs … See more Next, let's start building a simple model. Very small toy models typically do not benefit from mixed precision, because overhead from the TensorFlow runtime typically dominates … See more To use mixed precision in Keras, you need to create a tf.keras.mixed_precision.Policy, typically referred to as a dtype … See more Next, train the model: Notice the model prints the time per step in the logs: for example, "25ms/step". The first epoch may be slower as TensorFlow spends some time optimizing the model, but afterwards the time per step … See more
