turicreate.SArray.sample

SArray.sample(fraction, seed=None, exact=False)

Create an SArray which contains a subsample of the current SArray.

Parameters:

fraction : float

Fraction of the rows to fetch. Must be between 0 and 1. if exact is False (default), the number of rows returned is approximately the fraction times the number of rows.

seed : int, optional

The random seed for the random number generator.

exact: bool, optional

Defaults to False. If exact=True, an exact fraction is returned, but at a performance penalty.

Returns:

out : SArray

The new SArray which contains the subsampled rows.

Examples

>>> sa = turicreate.SArray(range(10))
>>> sa.sample(.3)
dtype: int
Rows: 3
