Version
name: Bernoulli (GitHub)
domain: main
since_version: 15
function: False
support_level: SupportType.COMMON
shape inference: True
This version of the operator has been available since version 15.
Summary
Draws binary random numbers (0 or 1) from a Bernoulli distribution. The input tensor should be a tensor containing probabilities p (a value in the range [0,1]) to be used for drawing the binary random number, where an output of 1 is produced with probability p and an output of 0 is produced with probability (1-p).
This operator is non-deterministic and may not produce the same values in different implementations (even if a seed is specified).
Attributes
dtype: The data type for the elements of the output tensor. if not specified, we will use the data type of the input tensor.
seed: (Optional) Seed to the random generator, if not specified we will auto generate one.
Inputs
input (heterogeneous) - T1: All values in input have to be in the range:[0, 1].
Outputs
output (heterogeneous) - T2: The returned output tensor only has values 0 or 1, same shape as input tensor.
Type Constraints
T1 in ( tensor(double), tensor(float), tensor(float16) ): Constrain input types to float tensors.
T2 in ( tensor(bfloat16), tensor(bool), tensor(double), tensor(float), tensor(float16), tensor(int16), tensor(int32), tensor(int64), tensor(int8), tensor(uint16), tensor(uint32), tensor(uint64), tensor(uint8) ): Constrain output types to all numeric tensors and bool tensors.
