chunks

emlib.numpytools.chunks(data, chunksize, hop=None, padwith=None)

Iterate over data in chunks of chunksize. Returns a generator

Parameters:

• data (ndarray) – the array to be iterated in chunks

• chunksize (int) – the size of each chunk

• hop (Optional[int]) – the amount of elements to skip between chunks, None to use chunksize as hop size

• padwith (Union[float, int, None]) – value to pad when a chunk is not big enough, None to avoid padding. The type depends on the data type of the given array

Return type:

Iterator[ndarray]

Returns:

a generator with chunks of data of chunksize or less
