mindspore.ops.StandardLaplace
- class mindspore.ops.StandardLaplace(seed=0, seed2=0)[source]
Generates random numbers according to the Laplace random number distribution (mean=0, lambda=1). It is defined as:
\[\text{f}(x;0,1) = \frac{1}{2}\exp(-|x|),\]- Inputs:
shape (tuple) - The shape of random tensor to be generated. Only constant value is allowed.
- Outputs:
Tensor. The shape that the input ‘shape’ denotes. The dtype is float32.
- Raises
TypeError – If neither seed nor seed2 is an int.
TypeError – If shape is not a tuple.
ValueError – If shape is not a constant value.
- Supported Platforms:
Ascend
Examples
>>> shape = (4, 16) >>> stdlaplace = ops.StandardLaplace(seed=2) >>> output = stdlaplace(shape) >>> result = output.shape >>> print(result) (4, 16)
