jax.random.poisson(key, lam, shape=(), dtype=<class 'numpy.int64'>)[source]¶

Sample Poisson random values with given shape and integer dtype.

Parameters

key – a PRNGKey used as the random key.
lam – rate parameter (mean of the distribution), must be >= 0.
shape – optional, a tuple of nonnegative integers representing the result shape. Default ().
dtype – optional, a integer dtype for the returned values (default int64 if jax_enable_x64 is true, otherwise int32).

Returns

A random array with the specified shape and dtype.
