jupyter notebook7.3.3版本无法进行代码补全

一、按tab键补全

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

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。

以上操作后，在编写代码是发现不是自动不全，是要按下tab键就可以补全了

二、自动补全

如果想自动代码补全。Jupyter Notebook 7.0以上版本移除了移除了 notebook.nbextensions 模块，所以通过如下方式安装nbextension，会报错：ModuleNotFoundError: No module named 'notebook.extensions'

• pip install jupyter_contrib_nbextensions

• jupyter contrib nbextension install --user

需通过界面设置，操作流程如下：

1、打开设置界面

2、打开autocompletion开关

3、验证效果
