+            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):
