mindspore.mint.arange

mindspore.mint.arange(start=0, end=None, step=1, *, dtype=None)[source]

Creates a sequence of numbers that begins at start and extends by increments of step up to but not including end.

Parameters
  • start (Union[float, int], optional) – The start of the interval. Default: 0 .

  • end (Union[float, int], optional) – The end of the interval, exclusive. Default: None . If None , it defaults to the value of start, and 0 is used as the starting value.

  • step (Union[float, int], optional) – The step size with which the array element increments. Default: 1 .

Keyword Arguments

dtype (mindspore.dtype, optional) –

The required data type of returned Tensor. Default: None . When dtype is not specified or None:

If start, end, and step are all integers, the dtype of output is int64,

If start, end, and step contain at least one floating-point number, the dtype of output is float32.

Returns

A 1-D Tensor, cast to dtype if provided, may potentially lose precision due to casting.
