Sample Poisson random values with given shape and integer dtype.

Parameters
  • key (ndarray) – a PRNGKey used as the random key.

  • lam (Any) – rate parameter (mean of the distribution), must be >= 0.

  • shape (Sequence[int]) – optional, a tuple of nonnegative integers representing the result shape. Default ().

  • dtype (Any) – optional, a integer dtype for the returned values (default int64 if jax_enable_x64 is true, otherwise int32).

Return type

ndarray

Returns

A random array with the specified shape and dtype.
