megengine.random.normal¶

normal(mean=0, std=1, size=None)¶

服从高斯分布的随机变量 \(N(\mu, \sigma)\)

参数

mean (float) – the mean or expectation of the distribution. Default: 0.
std (float) – the standard deviation of the distribution (variance = \(\sigma ^ 2\)). Default: 1.
size (Optional[Iterable[int]]) – the size of output tensor. Default: None.

返回

tensor. The random variable with Gaussian distribution.
