…emory Pull Request resolved: #16442 Add from_blob() factory function that creates SlimTensor from external memory without taking ownership. This enables creating tensors that wrap user-provided buffers for use in AOTI model execution. Changes: - Create factory/FromBlob.h with from_blob() overloads - Support sizes/strides as ArrayRef or initializer_list - Support custom storage offset - Add from_blob target to factory/targets.bzl ghstack-source-id: 335280566 @exported-using-ghexport Differential Revision: [D89950482](https://our.internmc.facebook.com/intern/diff/D89950482/)
Pull Request resolved: #16443 Add as_strided() and as_strided_() view operations that allow creating views of a tensor with different sizes, strides, and storage offset. Views share the same underlying storage. Changes: - Create c10/core/WrapDimMinimal.h for dimension wrapping - Create core/SlimTensorView-incl.h with as_strided implementations - Add as_strided() and as_strided_() methods to SlimTensor - Add set_sizes_and_strides() overload that takes storage_offset - Update build targets to include new headers ghstack-source-id: 335280569 @exported-using-ghexport Differential Revision: [D89951036](https://our.internmc.facebook.com/intern/diff/D89951036/)
