torch.sq

I believe you meant to type "torch.sqrt".

"torch.sqrt" is a function in the PyTorch library that computes the square root of the input tensor element-wise. It takes a tensor as input and returns a new tensor with the same shape as the input tensor, where each element is the square root of the corresponding element in the input tensor.

Here's an example:

import torch

x = torch.tensor([4.0, 9.0, 16.0])
y = torch.sqrt(x)

print(y) # Output: tensor([2., 3., 4.])
