Description

RKLLM software stack can help users to quickly deploy AI models to Rockchip chips. The overall framework is as follows:

In order to use RKNPU, users need to first run the RKLLM-Toolkit tool on the computer, convert the trained model into an RKLLM format model, and then inference on the development board using the RKLLM C API.

• RKLLM-Toolkit is a software development kit for users to perform model conversionand quantization on PC.

• RKLLM Runtime provides C/C++ programming interfaces for Rockchip NPU platform to help users deploy RKLLM models and accelerate the implementation of LLM applications.

• RKNPU kernel driver is responsible for interacting with NPU hardware. It has been open source and can be found in the Rockchip kernel code.

Model Performance

1. Benchmark results of common LLMs.

Performance Testing Methods

1. Run the frequency-setting script from the scripts directory on the target platform.
2. Execute export RKLLM_LOG_LEVEL=1 on the device to log model inference performance and memory usage.
3. Use the eval_perf_watch_cpu.sh script to measure CPU utilization.
4. Use the eval_perf_watch_npu.sh script to measure NPU utilization.

Download

1. You can download the latest package from RKLLM_SDK, fetch code: rkllm
2. You can download the converted rkllm model from rkllm_model_zoo, fetch code: rkllm

Examples

1. Multimodel deployment demo: Qwen2-VL_Demo
2. API usage demo: DeepSeek-R1-Distill-Qwen-1.5B_Demo
3. API server demo: rkllm_server_demo

Note

• The supported Python versions are:

  • Python 3.8
  • Python 3.9
  • Python 3.10
  • Python 3.11
  • Python 3.12

Note: Before installing package in a Python 3.12 environment, please run the command:

export BUILD_CUDA_EXT=0

• On some platforms, you may encounter an error indicating that libomp.so cannot be found. To resolve this, locate the library in the corresponding cross-compilation toolchain and place it in the board's lib directory, at the same level as librkllmrt.so.
• RWKV model conversion only supports Python 3.12. Please use requirements_rwkv7.txt to set up the pip environment.
• Latest version: v1.2.1

RKNN Toolkit2

If you want to deploy additional AI model, we have introduced a SDK called RKNN-Toolkit2. For details, please refer to:
