torch.Size

{class}torch.Size is the result type of a call to {func}torch.Tensor.size. It describes the size of all dimensions of the original tensor. As a subclass of {class}tuple, it supports common sequence operations like indexing and length.

Example:

    >>> x = torch.ones(10, 20, 30)
    >>> s = x.size()
    >>> s
    torch.Size([10, 20, 30])
    >>> s[1]
    20
    >>> len(s)
    3
