按照手册“9.算法工具链开发指南”的“9.2入门指南”中，解压模型转换环境和示例模型安装包并进行相关依赖的安装，执行如下命令时：
pip install ai_toolchain/h* -i https://mirrors.aliyun.com/pypi/simple

note: This error originates from a subprocess, and is likely not a problem with pip.
ERROR: Failed building wheel for pycocotools

Failed to build pycocotools
ERROR: Could not build wheels for pycocotools, which is required to install pyproject.toml-based projects
解决方法：
sudo apt-get install python3-dev
sudo apt-get install gcc
在Ubuntu中使用apt-get前建议先换源。
