jupyter是一种交互式计算和开发环境的笔记，ipython命令行比原生的python命令行更加友好和高效，还可以运行web版的界面，支持多语言，输出图形、音频、视频等功能。
安装
pip install jupyter
使用
2. 运行shell命令
感叹号!+shell直接运行shell命令，如!pwd运行python文件%run test.py(python文件)魔术函数的使用:
%time a = np.arange(1000)
%quickref 显示IPython的快速参考
%magic 显示所有魔术命令的详细文档
%debug 从最新的异常跟踪的底部进入交互式调试器
%hist 打印命令的输入（可选输出）历史
%pdb 在异常发生后自动进入调试器
%paste 执行剪贴板中的Python代码
%cpaste 打开一个特殊提示符以便手工粘贴待执行的Python代码
%reset 删除interactive命名空间中的全部变量/名称
%page OBJECT 通过分页器打印输出OBJECT
%run script.py 在IPython中执行一个Python脚本文件
%prun statement 通过cProfile执行statement，并打印分析器的输出结果
%time statement 报告statement的执行时间
%timeit statement 多次执行statement以计算系综平均执行时间。对那些执行时 间非常小的代码很有用
%who、%who_ls、%whos 显示interactive命名空间中定义的变量，信息级别/冗余度可变
%xdel variable 删除variable，并尝试清除其在IPython中的对象上的一切引用
3. 运行web ipython环境
jupyter notebooke --ip=127.0.0.1 --port=8888更多参数:
这将启动一个基于tornado的HTML笔记本服务器，它提供一个html5/javascript笔记本客户端。
Subcommands
-----------
Subcommands are launched as `jupyter-notebook cmd [args]`. For information on
using subcommand 'cmd', do: `jupyter-notebook cmd -h`.
list
列出当前运行的Notebook服务.
stop
Stop currently running notebook server for a given port
password
Set a password for the notebook server.
Options
-------
Arguments that take values are actually convenience aliases to full
Configurables, whose aliases are listed on the help line. For more information
on full configurables, see '--help-all'.
--debug
set log level to logging.DEBUG (maximize logging output)
--generate-config
generate default config file
-y
Answer yes to any questions instead of prompting.
--no-browser
在启动服务以后不在浏览器中打开一个窗口.
--pylab
DISABLED: use %pylab or %matplotlib in the notebook to enable matplotlib.
--no-mathjax
Disable MathJax
MathJax is the javascript library Jupyter uses to render math/LaTeX. It is
very large, so you may want to disable it if you have a slow internet
connection, or for offline use of the notebook.
When disabled, equations etc. will appear as their untransformed TeX source.
--allow-root
允许notebook在root用户下运行.
--script
DEPRECATED, IGNORED
--no-script
DEPRECATED, IGNORED
--log-level=<Enum> (Application.log_level)
Default: 30
Choices: (0, 10, 20, 30, 40, 50, 'DEBUG', 'INFO', 'WARN', 'ERROR', 'CRITICAL')
Set the log level by value or name.
--config=<Unicode> (JupyterApp.config_file)
Default: ''
Full path of a config file.
--ip=<Unicode> (NotebookApp.ip)
Default: 'localhost'
notebook服务会监听的IP地址.
--port=<Int> (NotebookApp.port)
Default: 8888
notebook服务会监听的IP端口.
--port-retries=<Int> (NotebookApp.port_retries)
Default: 50
如果指定的端口不可用，则要尝试其他端口的数量.
--transport=<CaselessStrEnum> (KernelManager.transport)
Default: 'tcp'
Choices: ['tcp', 'ipc']
--keyfile=<Unicode> (NotebookApp.keyfile)
Default: ''
SSL/TLS 私钥文件所在全路径.
--certfile=<Unicode> (NotebookApp.certfile)
Default: ''
SSL/TLS 认证文件所在全路径.
--client-ca=<Unicode> (NotebookApp.client_ca)
Default: ''
用于ssl/tls客户端身份验证的证书颁发证书的完整路径.
--notebook-dir=<Unicode> (NotebookApp.notebook_dir)
Default: ''
用于笔记本和内核的目录。
--browser=<Unicode> (NotebookApp.browser)
Default: ''
Specify what command to use to invoke a web browser when opening the
notebook. If not specified, the default browser will be determined by the
`webbrowser` standard library module, which allows setting of the BROWSER
environment variable to override it.
--pylab=<Unicode> (NotebookApp.pylab)
Default: 'disabled'
DISABLED: use %pylab or %matplotlib in the notebook to enable matplotlib.
--gateway-url=<Unicode> (GatewayClient.url)
Default: None
The url of the Kernel or Enterprise Gateway server where kernel
specifications are defined and kernel management takes place. If defined,
this Notebook server acts as a proxy for all kernel management and kernel
specification retrieval. (JUPYTER_GATEWAY_URL env var)
To see all available configurables, use `--help-all`
Examples
--------
jupyter notebook # start the notebook
jupyter notebook --certfile=mycert.pem # use SSL/TLS certificate
jupyter notebook password # enter a password to protect the server
常用命令:
1. 查看配置文件
jupyter notebook --generate-config如果配置文件不存在, 创建
ipython profile create
常用快捷键:
- 执行当前cell，并自动跳到下一个cell：Shift Enter
- 执行当前cell，执行后不自动调转到下一个cell：Ctrl-Enter
- 为一行或者多行添加/取消注释：Crtl /<br>打开帮助，Ctrl+Shirt+P
1. 添加代码自动补全
pip install jupyter_contrib_nbextensions安装完成,需要配置
jupyter contrib nbextension install --user --skip-running-check
启动jupyter notebook
页面上会出现 Nbextensions
勾选 Hinterland即可
具体使用的时候, 使用tab进行代码补全操作
2. 显示行号
查看 > 切换行号
3. 以守护进程方式运行
nohup jupyter notebook --ip=0.0.0.0 --port=8888 --allow-root > /dev/null 2>&1 &
4. 设置登陆密码
Jupiter notebook password常见错误：
1. python - Jupyter error: ＂No module named jupyter_core.paths＂
重新安装jupyter
2. ImportError: No module named '_sqlite3'
Traceback (most recent call last):File "decode_conv.py", line 6, in
import sqlite3
File "/usr/local/lib/python3.5/sqlite3/__init__.py", line 23, in
from sqlite3.dbapi2 import *
File "/usr/local/lib/python3.5/sqlite3/dbapi2.py", line 27, in
from _sqlite3 import *
ImportError: No module named '_sqlite3'
解决：
# 先安装 sqlite-devel
yum install sqlite-devel
# 之后需要将Python基于代码的安装包重新编译一下，并重新安装之后
./configure –prefix=python-install-folder
make & make install
