RuyiSDK 人工智能示例
本示例和 YOLOv8 示例步骤相同，仅替换为 YOLOv11 对应的 cvimodel 文件。
安装依赖库
sudo apt update
sudo apt install git make build-essential安装 RuyiSDK
安装ruyi包管理器（其他安装方式见官方安装文档）
wget https://mirror.iscas.ac.cn/ruyisdk/ruyi/tags/0.51.0/ruyi-0.51.0.amd64
chmod +x ./ruyi-0.51.0.amd64
sudo cp -v ./ruyi-0.51.0.amd64 /usr/local/bin/ruyi安装工具链
#初始化并更新 Ruyi 仓库
ruyi update
#下载 Duo 256M 专属工具链
ruyi install gnu-milkv-milkv-duo-musl-binYOLOv11
示例描述和硬件环境准备
基于 TDL SDK 实现 YOLOv11 目标检测，读取图像并进行推理，验证 Ruyi 工具链在 Duo 256M（RISC-V）上的交叉编译能力。
硬件环境：Milk-V Duo 256M （SG2002 ）
软件环境：Ubuntu，RuyiSDK 0.47.0，TDL SDK
创建并激活 ruyi 虚拟环境
# 创建虚拟环境
ruyi venv -t gnu-milkv-milkv-duo-musl-bin generic milkv-venv
# 激活
source milkv-venv/bin/ruyi-activate
# 验证
which riscv64-unknown-linux-musl-gcc在终端显示如下：
«Ruyi milkv-venv» duo256@duo256-virtual-machine:~$ which riscv64-unknown-linux-musl-gcc
/home/duo256/milkv-venv/bin/riscv64-unknown-linux-musl-gcc使用 ruyi 工具链编译示例代码
由于 Ultralytics 官方在设计 YOLOv11 时，延续了与 YOLOv8 相同的 Anchor-Free（无锚框）检测头架构，两者的模型输出张量（Tensor）维度和坐标解码逻辑高度一致。 因此，YOLOv11 可复用 sample_yolov8 示例程序进行推理验证。 获取 TDL-SDK 示例源码
