"""Generator to create n_packs slices going up to n.
"""Generator to create `n_packs` evenly spaced slices going up to `n`.

If `n_packs` does not divide `n`, except for the first `n % n_packs`
slices, remaining slices may contain fewer elements.

Parameters
----------
n : int
Size of the sequence.
n_packs : int
Number of slices to generate.
n_samples : int, default=None
Number of samples. Pass n_samples when the slices are to be used for
Number of samples. Pass `n_samples` when the slices are to be used for
sparse matrix indexing; slicing off-the-end raises an exception, while
it works for NumPy arrays.

Yields
------
slice
`slice` representing a set of indices from 0 to n.
