python ImageDataGenerator.next() code example

Example: what should I do when the keras image datagenerato is nit working

>>> k = np.random.randn(10,10) # Matrix 10x10
>>> import dask.array as da
>>> k2 = da.from_array(k,chunks = 3)
dask.array<array, shape=(10, 10), dtype=float64, chunksize=(3, 3)>
>>> k2.to_delayed()
