Serialize constant Data outside of flatbuffer (#1542) Summary: Pull Request resolved: https://github.com/pytorch/executorch/pull/1542 We introduce the `serialize_xnnpack_binary` method which serializees the constant data outside of the flatbuffer. It leverages the xnnheader introduced in the previous diff to store offsets and sizes for both the flatbuffer payload as well as the constant data payload. Note here we have not yet switched the delegate to use the new `serialize_xnnpack_binary` function as this new serialization also requires changes on the runtime side. This will be tested in the diff which follows. Reviewed By: digantdesai Differential Revision: D52498367 fbshipit-source-id: d90a246630653167ec479913f1862851ab8ace82
ExecuTorch is an end-to-end solution for enabling on-device inference capabilities across mobile and edge devices including wearables, embedded devices and microcontrollers. It is part of the PyTorch Edge ecosystem and enables efficient deployment of PyTorch models to edge devices.
Key value propositions of ExecuTorch are:

This is a preview version of ExecuTorch and should be used for testing and evaluation purposes only. It is not recommended for use in production settings. We welcome any feedback, suggestions, and bug reports from the community to help us improve the technology. Please use the PyTorch Forums for discussion and feedback about ExecuTorch using the ExecuTorch category, and our GitHub repository for bug reporting.
The ExecuTorch code and APIs are still changing quickly, and there are not yet any guarantees about forward/backward source compatibility. We recommend using the latest v#.#.#
