mindspore.numpy.arange

mindspore.numpy.arange(start, stop=None, step=None, dtype=None)

Returns evenly spaced values within a given interval.

Parameters

• start (Union[int, float]) – Start of interval. The interval includes this value. When stop is provided as a position argument, start must be given, when stop is a normal argument, start can be optional, and default: 0 . Please see additional examples below.

• stop (Union[int, float], optional) – End of interval. The interval does not include this value, except in some cases where step is not an integer and floating point round-off affects the length of out.

• step (Union[int, float], optional) – Spacing between values. For any output out, this is the distance between two adjacent values, $out[i+1]-out[i]$. The default step size is 1. If step is specified as a position argument, start must also be given.

• dtype (Union[mindspore.dtype, str], optional) – Designated tensor dtype. If dtype is None, the data type of the new tensor will be inferred from start, stop and step. Default: None .

Returns

Tensor with evenly spaced values.

Raises

• TypeError(PyNative Mode) – If input arguments have types not specified above, or arguments are not given in the correct orders specified above.

• RuntimeError(Graph Mode) – The inputs that lead to TypeError in Pynative Mode will lead to RuntimeError in Graph Mode.

Supported Platforms:

Examples

>>> import mindspore.numpy as np
>>> print(np.arange(0, 5, 1))
[0 1 2 3 4]
>>> print(np.arange(3))
[0 1 2]
>>> print(np.arange(start=0, stop=3))
[0 1 2]
>>> print(np.arange(0, stop=3, step=0.5))
[0.  0.5 1.  1.5 2.  2.5]
