- jax.numpy.arange(start, stop=None, step=None, dtype=None)#
Return evenly spaced values within a given interval.
LAX-backend implementation of
stepargument can lead to precision errors, especially with lower-precision data types like
bf16. For more details, see the docstring of
numpy.arange(). To avoid precision errors, consider using an expression like
(jnp.arange(-600, 600) * .01).astype(jnp.bfloat16)to generate a sequence in a higher precision and then convert it to the desired lower precision.
Original docstring below.
arangecan be called with a varying number of positional arguments:
arange(stop): Values are generated within the half-open interval
[0, stop)(in other words, the interval including start but excluding stop).
arange(start, stop): Values are generated within the half-open interval
arange(start, stop, step)Values are generated within the half-open interval
[start, stop), with spacing between values given by
For integer arguments the function is roughly equivalent to the Python built-in
range, but returns an ndarray rather than a
When using a non-integer step, such as 0.1, it is often better to use numpy.linspace.
See the Warning sections below for more information.
start (integer or real, optional) – Start of interval. The interval includes this value. The default start value is 0.
stop (integer or real) – 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 (integer or real, 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 (dtype, optional) – The type of the output array. If dtype is not given, infer the data type from the other input arguments.
arange – Array of evenly spaced values.
For floating point arguments, the length of the result is
ceil((stop - start)/step). Because of floating point overflow, this rule may result in the last element of out being greater than stop.
