jax.numpy.empty(shape, dtype=None)[source]#

Return a new array of given shape and type, without initializing entries.

LAX-backend implementation of numpy.empty().

Because XLA cannot create uninitialized arrays, the JAX version will return an array initialized with zeros.

Original docstring below.

  • shape (int or tuple of int) – Shape of the empty array, e.g., (2, 3) or 2.

  • dtype (data-type, optional) – Desired output data-type for the array, e.g, numpy.int8. Default is numpy.float64.


out – Array of uninitialized (arbitrary) data of the given shape, dtype, and order. Object arrays will be initialized to None.
