ByOp

This generated catalogue lists every kernel exposed by onnx_light_cpu.registered_kernels(). Each kernel page includes its registration metadata and the CPU-specific schema, shape inference, peak-memory, fusion-pattern, and gradient support available for that operator.

Kernels

This catalogue is generated from onnx_light_cpu.registered_kernels(). Each row links to one kernel registration and its available operator support.
