要查看 PyTorch 中特定函数的用法，可以使用 help() 函数，如下所示：
import torch
# 查看torch中add函数的用法
help(torch.add)
这将打印出 torch.add 函数的帮助文档，包括函数的参数、返回值、用法示例等。您也可以在 Jupyter Notebook 或 IPython 中使用 ? 符号来查看帮助文档，如下所示：
import torch
# 查看torch中add函数的用法
torch.add?
这将显示与上面 help(torch.add) 相同的帮助文档。
Output exceeds the size limit. Open the full output data in a text editor
Docstring:
add(input, other, *, out=None)
Adds the scalar :attr:`other` to each element of the input :attr:`input`
and returns a new resulting tensor.
.. math::
\text{out} = \text{input} + \text{other}
If :attr:`input` is of type FloatTensor or DoubleTensor, :attr:`other` must be
a real number, otherwise it should be an integer.
Args:
input (Tensor): the input tensor.
value (Number): the number to be added to each element of :attr:`input`
Keyword arguments:
out (Tensor, optional): the output tensor.
Example::
>>> a = torch.randn(4)
>>> a
tensor([ 0.0202, 1.0985, 1.3506, -0.6056])
>>> torch.add(a, 20)
