Img preprocess_input img mode tf
WitrynaThe preprocessing function takes an Image instance as its input and outputs the processed features that the ML model consumes. In this example, each image in the Image object is transformed via tf.keras.preprocessing.image.img_to_array followed by mobilenet_v2.preprocess_input. WitrynaTable 1 Training flow Step Description Preprocess the data. Create the input function input_fn. Construct a model. Construct the model function model_fn. Configure run parameters. Instantiate Estimator and pass an object of the Runconfig class as the run parameter. Perform training.
