篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了树莓派为啥不支持android相关的知识，希望对你有一定的参考价值。
参考技术A 树莓派(raspberry pi)是英国产品，默认键盘布局是英国(GB)，我们用的键盘布局一般是美国(US)的更改键盘布局，命令如下:sudo dpkg-reconfigure keyboard-configuration进入后，选通用的101键PC键盘本文来自电脑网 按tab键，到OK，按Enter确定在键盘layout选择中，选Other 然后在选项中，选English(US)按tab键，到OK，按Enter确定再选English(US, alternative international)树莓派(raspberry pi)学习4: 更改键盘布局按tab键，到OK，按Enter确定然后一路按OK退出后，重启系统sudo reboot重新启动时，由于修改了键盘布局，在读取键盘布局的阶段会比平常慢一些OK了， 终于可以打出所有字符了这一点，linux还是不太方便，windows比较人性化一些为啥 Jupyter notebook 不能在我的树莓派上运行
【中文标题】为啥 Jupyter notebook 不能在我的树莓派上运行【英文标题】：Why isn't Juypter notebook working on my raspberry pi为什么 Jupyter notebook 不能在我的树莓派上运行 【发布时间】：2020-07-14 11:41:02 【问题描述】：我在全新安装的 debian for pi 上安装了 Jupyter notebook。我让它在以前的安装中完美运行。我不明白为什么它不适用于此安装。内核不会启动。

有人能帮我解释一下我的情况吗？
【问题讨论】：
【参考方案1】：使用下面的 cmd 将 ~/.local/share/jupyter 目录的所有权从 root 更改为 pi：
sudo chown -R pi:pi ~/.local/share/jupyter
【讨论】：
【参考方案2】：如果您的内核无法启动或显示任何对我有用的问题，请运行此命令 "pip3 install --force-reinstall --upgrade jupyter"
