torch.randn

torch.randn is a function in the PyTorch library that generates a tensor with random values drawn from a standard normal distribution (mean=0, standard deviation=1). It takes in a size argument which specifies the shape of the output tensor.

For example, the following code generates a tensor of size (3, 4) with random values:

import torch

x = torch.randn(3, 4)
print(x)

Output:

tensor([[-0.5828,  0.2436,  0.1174, -0.8029],
        [ 0.3970, -0.5141, -0.1323,  0.5626],
        [-0.4569, -0.0591,  0.6372,  0.4185]])
