jax.random.normal#
- jax.random.normal(key, shape=(), dtype=<class 'float'>)[source]#
Sample standard normal random values with given shape and float dtype.
The values are returned according to the probability density function:
\[f(x) = \frac{1}{\sqrt{2\pi}}e^{-x^2/2}\]on the domain \(-\infty < x < \infty\)
- Parameters:
key (
Union
[Array
,ndarray
,bool_
,number
,bool
,int
,float
,complex
]) – a PRNG key used as the random key.shape (
Union
[Sequence
[int
],NamedShape
]) – optional, a tuple of nonnegative integers representing the result shape. Default ().dtype (
Union
[str
,type
[Any
],dtype
,SupportsDType
]) – optional, a float dtype for the returned values (default float64 if jax_enable_x64 is true, otherwise float32).

A random array with the specified shape and dtype.
