WebIn computing, half precision (sometimes called FP16 or float16) is a binary floating-point computer number format that occupies 16 bits (two bytes in modern computers) in computer memory. It is intended for storage of floating-point values in applications where higher precision is not essential, in particular image processing and neural networks . WebDec 15, 2024 · The first layer of the model will cast the inputs to float16, as each layer casts floating-point inputs to its compute dtype. The initial weights of the model are retrieved. This will allow training from scratch again by loading the weights. initial_weights = model.get_weights() Training the model with Model.fit Next, train the model:
