Question

[enssaf]

please,, help me, how could I combine 3 numerical vectors with image features vectors using a generator, what is wrong in this code

def combined_generators(image_generator, x_data, y_data, z_data, batch_size):
x_gen = cycle(batch(x_data, batch_size))
y_gen = cycle(batch(y_data, batch_size))
z_gen = cycle(batch(z_data, batch_size))

while True:
    nextImage = next(image_generator)
    
    nextx = next(x_gen)
    assert len(nextImage[0]) == len(nextx)

    nexty = next(y_gen)
    assert len(nextImage[0]) == len(nexty)

    nextz = next(z_gen)
    assert len(nextImage[0]) == len(nextz)
    
    yield [nextImage[0], nextx, nexty, nextz], nextImage[1]

def batch(iterable, n=1):
l = len(iterable)
for ndx in range(0, l, n):
yield iterable[ndx:min(ndx + n, l)]

train_gen_wrapper = combined_generators(train_batches, df['x'], df['y'], df['z'], 16)
val_gen_wrapper = combined_generators(valid_batches, dft['x'], dft['y'], dft['z'], 16)
