RKNN

RKNN is the model conversion and inference software toolchain for Rockchip NPUs. Select the documentation according to the SDK generation and software compatibility requirements:

  • RKNN2: model conversion, performance evaluation, and inference deployment toolchain.
  • RKNN3: next-generation model conversion, runtime, and inference deployment toolchain.

The toolkits, runtimes, and model formats of RKNN2 and RKNN3 are incompatible and must not be mixed.
