Bernoulli - version 15
======================

This page documents version **15** of operator **Bernoulli**. See :doc:`Bernoulli` for the latest version (since version 22).

- **Domain**: ``ai.onnx``
- **Since version**: 15

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).

**Inputs**

- **input** (*T1*): All values in input have to be in the range:[0, 1].

**Outputs**

- **output** (*T2*): The returned output tensor only has values 0 or 1, same shape as input tensor.

**Attributes**

- **dtype** (*int*): The data type for the elements of the output tensor. if not specified, we will use the data type of the input tensor.
- **seed** (*float*): (Optional) Seed to the random generator, if not specified we will auto generate one.

**Type Constraints**

- **T1**: Constrain input types to float tensors.
  Allowed types: tensor(double), tensor(float), tensor(float16).
- **T2**: Constrain output types to all numeric tensors and bool tensors.
  Allowed types: 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).
