ciflow/inductor/178083: Update inductor expected accuracy files

The PyTorch team has executed a routine but crucial maintenance update to its AI compilation infrastructure. Commit ciflow/inductor/178083, processed by the automated 'pytorchbot', refreshes the 'expected accuracy' CSV files for the PyTorch Inductor compiler. Inductor is PyTorch's just-in-time (JIT) compiler, responsible for accelerating deep learning models by generating optimized kernel code. These CSV files act as a golden dataset, containing benchmark results that define the correct, expected output—both in terms of numerical accuracy and graph structure—for a suite of standard models and operations.

This update is sourced directly from the Continuous Integration (CI) pipeline, using results generated from a specific, verified parent commit. The primary function is regression detection: every time new code is submitted to PyTorch, the CI system compiles test models with Dynamo/Inductor and compares the new results against these reference files. If the numerical outputs diverge beyond a tolerance (an accuracy regression) or if the compiler breaks the computational graph differently (a graph break regression), the test fails. This prevents changes that inadvertently degrade the performance or correctness of compiled models, which could affect downstream training and inference for frameworks and companies relying on PyTorch.

While not a user-facing feature launch, this update is foundational for maintaining the stability and reliability of the entire PyTorch compilation stack. It ensures that performance improvements or bug fixes introduced by developers do not come at the cost of silent accuracy losses. For AI engineers and researchers, this behind-the-scenes work translates to confidence that their models—whether based on Transformer architectures like Llama 3 or custom CNNs—will compile consistently and correctly across different versions of the PyTorch ecosystem.
