- Parameters:
key (
Union
[Array

,bool_
,number
,bool
,int
,float
,complex
]) – a PRNG key used as the random key.d (
int
) – a nonnegative int representing the dimensionality of the ball.p (
float
) – a float representing the p parameter of the Lp norm.shape (
Sequence
[int
]) – optional, the batch dimensions of the result. Default ().dtype (

]) – optional, a float dtype for the returned values (default float64 if jax_enable_x64 is true, otherwise float32).
- Returns:
A random array of shape (*shape, d) and specified dtype.
