anaconda jupyternotebook 补全
jupyter notebook代码自动补全
一直用anaconda自带的spyder写代码，今天突然想试试jupyternotebook，写了一会总觉得没有代码补全不太方便，就百度查，然后总结了以下步骤如下：
1、命令行执行安装nbextensions
pip install jupyter_contrib_nbextensions -i https://pypi.mirrors.ustc.edu.cn/simple
jupyter contrib nbextension install --user
2、安装nbextensions_configurator
pip install --user jupyter_nbextensions_configurator
jupyter nbextensions_configurator enable --user
这两部完成后，基本就可以了，网上说有可能会有报错，缺少依赖环境，这个我倒没遇到，如果真缺少了，那就根据提示pip或者conda install就好了
另外插一嘴：在命令行窗口运行jupyter notebook时候，命令行窗口所在的文件夹是哪个位置，运行后的根目录就是那个位置：如下：我是直接win+r–>cmd–>jjupyter notebook，在默认位置运行的，就出现这样的：
3、上面的安装完成后，记得重启jupyter，就可以看到那个Nbextensions标签了，点击它，出现下面的界面，勾选Hinterland
4、结果：连from都可以提示，结果棒棒哒
PS:上面的是安装了插件，又看到一个方法，据说可以直接修改配置文件就行，我没测试，先收藏：
ipython profile create
执行上述命令后会在.ipython/profile_default/目录下生成ipython_config.py和ipython_kernel_config.py
修改以下几行即可：
## 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即可
