Pytorch expand dim. Tensor can be also expanded to a larger number of dimensions, and the new ones will be appended at the front. expand(*sizes) → Tensor Returns a new view of the self tensor with singleton dimensions expanded to a larger size. Dec 28, 2020 · How to add a new dimension to a PyTorch tensor? Asked 4 years, 8 months ago Modified 3 years, 5 months ago Viewed 122k times Mar 9, 2017 · Learn how to use None indexing or unsqueeze() function to add a dimension to a tensor in PyTorch. Tensor. The `expand` method allows us to expand the dimensions of a tensor without actually replicating the underlying data. Passing -1 as the size for a dimension means not changing the size of that dimension. May 15, 2025 · The . expand Tensor. This operation is memory-efficient, as it doesn’t allocate new memory but instead returns a view where the singleton dimensions are expanded to the desired size. This is extremely helpful when dealing with broadcasting and other tensor operations, as it provides a memory torch. One of the useful operations in PyTorch is the `expand` method. 8k次，点赞2次，收藏6次。本文介绍了如何使用PyTorch中的unsqueeze操作来增加张量的维度，并提供了实例代码。此外，还对比了unsqueeze与unsqueeze_的区别。 Jul 3, 2025 · In the realm of deep learning, PyTorch has emerged as one of the most popular and powerful frameworks. expand # Tensor. expand() function in PyTorch creates a new view of a tensor by expanding its singleton dimensions (dimensions with size 1) to a larger size. For the new dimensions, the size cannot be set to -1 . torch. expand(*sizes) → Tensor # Returns a new view of the self tensor with singleton dimensions expanded to a larger size.
