WebAug 23, 2024 · The stride is an interface for your tensor to access the underlying contiguous data buffer. It does not insert values, no copies of the values are done by torch.as_strided, the strides define the artificial layout of what we refer to as multi-dimensional array (in NumPy) or tensor (in PyTorch). As Andreas K. puts it in another answer: WebBuiltin Dialect The builtin dialect contains a core set of Attributes, Operations, and Types that have wide applicability across a very large number of domains and abstractions. Many of the components of this dialect are also instrumental in the implementation of the core IR. flight hm61
