瑞芯微(EASY EAI)RV1126B AI模型转换

1. AI模型转换

本章主要说明如何实现Hugging Face格式的大语言模型（Large Language Model, LLM）

如何转换为RKLLM模型，目前支持的模型包括Deepseek、LLaMA, Qwen, Qwen2, Phi-2, Phi-3, ChatGLM3, Gemma, InternLM2 和 MiniCPM等，本章以Deepseek-R1为例。

本章主要说明如何实现Deepseek-R1大语言模型如何转换为RKLLM模型。

1.1 模型下载

本节提供两种大模型文件，Hugging face的原始模型和转换完成的NPU模型。

1.2 模型转换

下载完成后模型和脚本放到同一个目录:

在RKLLM-Toolkit环境，执行以下指令进行模型转换:

至此模型转换成功,生成deepseek_r1_rv1126b_w4a16.rkllm NPU化的大模型文件：

test.py转换脚本如下所示, 用于转换DeepSeek-R1-Distill-Qwen-1.5B模型:
