Creating image generator and training model in keras
In the code below I'm getting the following error: TypeError: fit_generator() missing 1 required positional argument: 'generator'. This would be the first argument given in the code right? Can anyone explain why I still get this error and how to solve it?
x_train is of shape (400, 256, 256, 4) dtype = float64.
y_train is shape (400, 256, 256) dtype = uint8.
x_val is of shape (100, 256, 256, 4) dtype = float64.
y_val is shape (100, 256, 256) dtype = uint8.
# Create image generator
data_gen_args = dict(rotation_range=5,
width_shift_range=0.1,
height_shift_range=0.1,
validation_split=0.2)
image_datagen = ImageDataGenerator(**data_gen_args)
seed = 1
batch_size = 4
def XYaugmentGenerator(X1, y, seed, batch_size):
genX1 = gen.flow(X1, y, batch_size=batch_size, seed=seed)
genX2 = gen.flow(y, X1, batch_size=batch_size, seed=seed)
while True:
X1i = genX1.next()
X2i = genX2.next()
yield X1i[0], X2i[0]
# Train model
Model.fit_generator(XYaugmentGenerator(x_train, y_train, seed, batch_size), steps_per_epoch=np.ceil(float(len(images)) / float(batch_size)),
validation_data = XYaugmentGenerator(x_val, y_val,seed, batch_size),
validation_steps = np.ceil(float(len(x_val)) / float(batch_size))
, shuffle=True, epochs=20)
The complete error with traceback is given below:
