树莓派2 是一款很老的开发板了，但是它还能继续战斗。为了更好的编程体验，准备安装jupyterlab
安装jupyterlab
使用命令：
pip install jupyterlab该过程非常漫长，因为树莓派2是很老的板子，它需要安装一些arm7版本的软件，下载速度非常慢。即使配置了清华加速源，一些特别的软件还是要到piwheels去拿。下面分别为清华源和piwheels源：
https://mirrors.huaweicloud.com/repository/pypi/simple/
https://www.piwheels.org/simple
安装好后，发现安装了很多软件：

启动jupyter-lab
jupyter-lab启动可以联网访问的jupyter-lab
jupyter-lab --ip 0.0.0.0事实上如果不想费力将jupyter放到systemctl里面，启动时可以用这句指令：
nohup jupyter-lab --ip 0.0.0.0 &运行后输入
tail -f nohup.out就可以看到输出信息了，比如我们需要拿到链接地址，类似：
http://rbpi:8888/lab?token=xxxeb0e75f1d5f7698a47e19dcddc27xxxx
然后用这个地址上网，就可以开始我们的jupyter编程之旅了！
