# Description

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

        <img src="res/framework.jpg" title="RKLLM"/>
    </center>

  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](https://github.com/airockchip/rknn-llm/tree/main/benchmark.md) 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](https://console.zbox.filez.com/l/RJJDmB), fetch code: rkllm
2. You can download the **converted rkllm model**  from [rkllm_model_zoo](https://console.box.lenovo.com/l/l0tXb8), fetch code: rkllm

# Examples

1. Multimodel deployment demo:   [multimodal_model_demo](https://github.com/airockchip/rknn-llm/tree/main/examples/multimodal_model_demo)
2. API usage demo:  [rkllm_api_demo](https://github.com/airockchip/rknn-llm/tree/main/examples/rkllm_api_demo)
3. API server demo:  [rkllm_server_demo](https://github.com/airockchip/rknn-llm/tree/main/examples/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: [ <u>v1.2.2](https://github.com/airockchip/rknn-llm/releases/tag/release-v1.2.2)</u>

# RKNN Toolkit2
