Taken from https://stackoverflow.com/a/8998040. See also https://github.com/huggingface/huggingface_hub/pull/920#discussion_r938793088. Args: iterable (`Iterable`): The iterable on which we want to iterate. chunk_size (`int`): Size of the chunks. Must be a strictly positive integer (e.g. >0). Example: ```python >>> from huggingface_hub.utils import chunk_iterable >>> for items in chunk_iterable(range(17), chunk_size=8): ... print(items) # [0, 1, 2, 3, 4, 5, 6, 7] # [8, 9, 10, 11, 12, 13, 14, 15] # [16] # smaller last chunk ``` Raises: [`ValueError`](https://docs.python.org/3/library/exceptions.html#ValueError) If `chunk_size` <= 0. > [!WARNING] > The last chunk can be smaller than `chunk_size`. rz6`chunk_size` must be a strictly positive integer (>0).N) isinstanceint ValueErroriternext StopIteration itertoolschainislice)rriterator next_items a/var/www/html/ia-enhanced/venv/lib/python3.12/site-packages/huggingface_hub/utils/_chunk_utils.pychunk_iterablers}> j# &*/QRRH~H  XIooylI,<,rsK@$ CL(XXa[(Xc(XhxPQ{>S(Xr
