torch.normal — PyTorch 1.10.0 documentation torch.normal torch.normal(mean, std, *, generator=None, out=None) → Tensor Returns a tensor of random numbers drawn from separate normal distributions whose mean and standard deviation are given. The mean is a tensor with the mean of each output element’s normal distribution

torch.randn — PyTorch 1.10.0 documentation torch.randn torch.randn(*size, *, out=None, dtype=None, layout=torch.strided, device=None, requires_grad=False) → Tensor Returns a tensor filled with random numbers from a normal distribution with mean 0 and variance 1 (also called the standard normal distribution).

01.07.2018 · You can create your distribution like described here in the docs. In your case this should be the correct call, including sampling from the created distribution: from torch.distributions import normal m = normal.Normal (4.0, 0.5) s = m.sample () If you want to get a sample of a certain size/shape, you can pass it to sample (), for example.

A simple option is to use the randn function from the base module. It creates a random sample from the standard Gaussian distribution. To change ...

Probability distributions - torch.distributions. The distributions package contains parameterizable probability distributions and sampling functions. This allows the construction of stochastic computation graphs and stochastic gradient estimators for optimization. This package generally follows the design of the TensorFlow Distributions package.
