jupyter notebook自动补全功能实现

Jupyter notebook使用默认的自动补全是关掉的。要打开自动补全,需修改默认配置。

 

命令行中输入:ipython profile create

以上命令会在~/.ipython/profile_default/目录下生成ipython_config.py和ipython_kernel_config.py

 

我们需要修改(ipython_config.py)的以下几行,将开启补全功能:

## Activate greedy completion PENDING DEPRECTION. this is now mostly taken care
#  of with Jedi.
#
#  This will enable completion on elements of lists, results of function calls,
#  etc., but can be unsafe because the code is actually evaluated on TAB.
c.Completer.greedy = True
## Experimental: restrict time (in milliseconds) during which Jedi can compute
#  types. Set to 0 to stop computing types. Non-zero value lower than 100ms may
#  hurt performance by preventing jedi to build its cache.
c.Completer.jedi_compute_type_timeout = 400
## Experimental: Use Jedi to generate autocompletions. Off by default.
c.Completer.use_jedi = True

重启jupyter后生效。

 

注:以上操作后,在编写代码是发现不是自动不全,是要按下tab键才可以补全,所以还是有些不便,还好有插件,通过Hinterland插件即可解决自动补全问题了,安装配置步骤:

1、在命令行中激活代码补全环境(注:如果使用的是默认环境则不需要激活)

2、安装nbextensions(以下不截图了,在cmd环境中运行即可,在安装过程中如有提示缺少的库安装即可)

pip install jupyter_nbextensions_configurator

jupyter nbextensions_configurator enable –user

3、重启jupyter,在弹出的主页面里,能看到增加了一个Nbextensions标签页,在这个页面里,勾选Hinterland即启用了代码自动补全。

注:如果页面无Hinterland项,或者不全,命令行执行:

jupyter contrib nbextension install --user --skip-running-check

再次重启jupyter,Nbextensions标签页中数据将全部出现了

 

 在输入代码后,会自动补全了,不用再按tab键了,快很多了吧
