WebJul 11, 2024 · A better intuition for PyTorch dimensions by visualizing the process of summation over a 3D tensor. Photo by Crissy Jarvis on Unsplash. When I started doing some basic operations with PyTorch … Webtorch.sort torch.sort(input, dim=- 1, descending=False, stable=False, *, out=None) Sorts the elements of the input tensor along a given dimension in ascending order by value. If dim is not given, the last dimension of the input is chosen. If descending is True then the elements are sorted in descending order by value.
We can find that the dimensions are arranged the same as using permute(), the order of the elements in the tensor will not change. In addition, view() can not only replace the order of dimensions, but also directly change the dimensions. For example, we can put all the elements just now in the same dimension: See more permute() is mainly used for the exchange of dimensions, and unlike view(), it disrupts the order of elements of tensors. Let’s take a look for an example: Output: This is a simple tensor arranged in numerical order with … See more Compared with permute(), view()does not disrupt the order of elements and is much more free.
