jax.numpy.array#

jax.numpy.array(object, dtype=None, copy=True, order='K', ndmin=0)[source]#

Create an array.

LAX-backend implementation of numpy.array().

This function will create arrays on JAX’s default device. For control of the device placement of data, see jax.device_put(). More information is available in the JAX FAQ at Controlling data and computation placement on devices (full FAQ at https://jax.readthedocs.io/en/latest/faq.html).

Original docstring below.

Parameters

  • object (array_like) – An array, any object exposing the array interface, an object whose __array__ method returns an array, or any (nested) sequence. If object is a scalar, a 0-dimensional array containing object is returned.

  • dtype (data-type, optional) – The desired data-type for the array. If not given, NumPy will try to use a default dtype that can represent the values (by applying promotion rules when necessary.)

  • copy (bool, optional) – If true (default), then the object is copied. Otherwise, a copy will only be made if __array__ returns a copy, if obj is a nested sequence, or if a copy is needed to satisfy any of the other requirements (dtype, order, etc.).

  • order ({'K', 'A', 'C', 'F'}, optional) –

    Specify the memory layout of the array. If object is not an array, the newly created array will be in C order (row major) unless ‘F’ is specified, in which case it will be in Fortran order (column major). If object is an array the following holds.

    order

    no copy

    copy=True

    ’K’

    unchanged

    F & C order preserved, otherwise most similar order

    ’A’

    unchanged

    F order if input is F and not C, otherwise C order

    ’C’

    C order

    C order

    ’F’

    F order

    F order

    When copy=False and a copy is made for other reasons, the result is the same as if copy=True, with some exceptions for ‘A’, see the Notes section. The default order is ‘K’.

  • ndmin (int, optional) – Specifies the minimum number of dimensions that the resulting array should have. Ones will be prepended to the shape as needed to meet this requirement.

Returns

out – An array object satisfying the specified requirements.
