Quantization constructs a model which emulates quantization during training. This allows the model to learn parameters robust to quantization loss, and also model the accuracy of a quantized model.

Quantize a model:
# Quantize sequential model model = quantize_model( keras.Sequential([ layers.Dense(10, activation='relu', input_shape=(100,)), layers.Dense(2, activation='sigmoid') ])) # Quantize functional model in = tf.keras.Input((3,)) out = tf.keras.Dense(2)(in) model = tf.keras.Model(in, out) quantized_model = quantize_model(model)
Note that this function removes the optimizer from the original model.
The returned model copies over weights from the original model. So while it preserves the original weights, training it will not modify the weights of the original model.
