1.初步感受Jupyter Notebook
Jupyter Notebook
官网地址：Jupyter Notebook
Jupyter Notebook（此前被称为 IPython notebook）是一个交互式笔记本，支持运行 40 多种编程语言。
Jupyter Notebook 的本质是一个 Web 应用程序，便于创建和共享程序文档，支持实时代码，数学方程，可视化和 markdown。 用途包括：数据清理和转换，数值模拟，统计建模，机器学习等等 。
Jupyter Notebook: The Classic Notebook Interface
Try it your Browser可以使用本地浏览器预览效果
首先打开一个R语言的浏览器界面如下
2.Jupyter Notebook安装
使用pip安装
首先使用’win+r’ 输入cmd 打开命令提示行
使用cd命令定位到python编译器路径下，一般默认路径为：
C:\Users\Administrator\AppData\Local\Programs\Python\Python37\Scripts
输入命令：cd C:\Users\Administrator\AppData\Local\Programs\Python\Python37\Scripts
输入命令：pip install jupyter
刚使用就报错了，如下：

raise ValueError("check_hostname requires server_hostname")
ValueError: check_hostname requires server_hostname
即“ValueError: check_hostname requires server_hostname”错误，这个由于系统使用了代理引起的，停止使用就好了。
关掉代理继续执行结果如下（我的地址放在D盘了）：

有的可能系统已经有合适的版本，就跳过安装了，在安装tornado出现一下错误：

问题原因：升级的时候忘记关PyCharm，导致pip被占用，关掉重新输入pip install jupyter notebook就好了。

You should consider upgrading via the 'd:\pythonproject\venv\scripts\python.exe -m pip install --upgrade pip' command.
继续输入：jupyter notebook
或者在浏览器地址栏输入：localhost:8888/tree
点击upload按钮，上传对应的ipynb文件，上传成功后点击打开
点击run按钮，即可开始运行代码。
3.Jupyter Notebook测试
按照上面提示的，我们上传一个项目文件，可以在github上下载一个文件上传测试。
运行一下，显示有错误，需要进一步调试运行环境。
此外，我们还可以安装函数提醒的库，命令：pip install jupyter_contrib_nbextensions
至此，本文结束，希望对大家有所帮助。
