参数 | ||
:::::::::: | ||
- **lower** (float,可选) - 负值斜率的随机值范围下限,`lower` 包含在范围中。支持的数据类型:float。默认值为0.125。 | ||
- **upper** (float,可选) - 负值斜率的随机值范围上限,`upper` 包含在范围中。支持的数据类型:float。默认值为0.333。 | ||
- **name** (str,可选) - 操作的名称(可选,默认值为None)。更多信息请参见 :ref:`api_guide_Name`。 | ||
|
||
形状 | ||
:::::::::: | ||
- **x** (Tensor) – 任意形状的Tensor,默认数据类型为float32。 | ||
- **out** (Tensor) – 和x具有相同形状的Tensor。 | ||
