Я строю последовательную модель следующим образом:
## build the model
model = tf.keras.Sequential()
model.add(tf.keras.layers.Dense(32, activation='relu', batch_input_shape=(None, 8)))
model.add(tf.keras.layers.Dense(32, activation='relu'))
model.add(tf.keras.layers.Dense(1, activation=None))
Теперь я получу конфиги и буду использовать ее для повторной инициализации новой модели:
## get the config
config = model.get_config()
## re-build the model from config
model2 = tf.keras.Model.from_config(config)
Но это даетKeyError: 'name' следующим образом:
