deepctr_torch.layers.utils.slice_arrays(arrays, start=None, stop=None)

Slice an array or list of arrays.

This takes an array-like, or a list of array-likes, and outputs:

• arrays[start:stop] if arrays is an array-like
• [x[start:stop] for x in arrays] if arrays is a list

Can also work on list/array of indices: slice_arrays(x, indices)

Arguments:

arrays: Single array or list of arrays. start: can be an integer index (start index)

or a list/array of indices

stop: integer (stop index); should be None if

start was a list.

Returns:

A slice of the array(s).

Raises:

ValueError: If the value of start is a list and stop is not None.
