安裝Runtime
$ echo "deb https://packages.cloud.google.com/apt coral-edgetpu-stable main" | sudo tee /etc/apt/sources.list.d/coral-edgetpu.list
$ curl https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add -
$ sudo apt-get update
安裝Pyenv (切換至Python 3.9)
$ curl https://pyenv.run | bash
根據Terminal畫面，新增環境辨識至.zshrc or .bashrc
$ pyenv install 3.9.18
$ pyenv global 3.9.18
$ python --version #重開Terminal後測試版本
如果要切回原本的版本
$ pyenv rehash
$ pyenv global system
