## RandomNormal - 22

### Version

- **name**: [RandomNormal (GitHub)](https://github.com/onnx/onnx/blob/main/docs/Operators.md#RandomNormal)
- **domain**: `main`
- **since_version**: `22`
- **function**: `False`
- **support_level**: `SupportType.COMMON`
- **shape inference**: `True`

This version of the operator has been available
**since version 22**.

### Summary

Generate a tensor with random values drawn from a normal distribution. The shape
of the tensor is specified by the `shape` argument and the parameter of the normal distribution
specified by `mean` and `scale`.

The data type is specified by the 'dtype' argument. The 'dtype' argument must
be one of the data types specified in the 'DataType' enum field in the
TensorProto message.

### Attributes

* **dtype - INT** (default is `'1'`):

  The data type for the elements of the output tensor. Default is TensorProto::FLOAT.

* **mean - FLOAT** (default is `'0.0'`):

  The mean of the normal distribution.

* **scale - FLOAT** (default is `'1.0'`):

  The standard deviation of the normal distribution.

* **seed - FLOAT** :

  (Optional) Seed to the random generator, if not specified we will auto generate one.

* **shape - INTS** (required) :

  The shape of the output tensor.

### Outputs

- **output** (heterogeneous) - **T**:

  Output tensor of random values drawn from normal distribution

### Type Constraints

* **T** in ( `tensor(bfloat16)`, `tensor(double)`, `tensor(float)`, `tensor(float16)` ):

  Constrain output types to float tensors.
