: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
