jax.random.gamma¶

jax.random.gamma(key, a, shape=None, dtype=<class 'numpy.float64'>)[source]¶

Sample Gamma random values with given shape and float dtype.

Parameters

key – a PRNGKey used as the random key.
a – a float or array of floats broadcast-compatible with shape representing the parameter of the distribution.
shape – optional, a tuple of nonnegative integers specifying the result shape. Must be broadcast-compatible with a. The default (None) produces a result shape equal to a.shape.
dtype – optional, a float dtype for the returned values (default float64 if jax_enable_x64 is true, otherwise float32).

Returns

A random array with the specified dtype and with shape given by shape if shape is not None, or else by a.shape.
