如何在MacOS的jupyter Notebook中显示所有可能的方法?

本文介绍了如何在MacOS的jupyter Notebook中显示所有可能的方法?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

我在 MacOS

许多人没有在MacOS中发现这些答案，就像您在评论中看到的那样.

Many people didn't find those answers useful in MacOS as you can see in the comments.

我正在尝试使用. + tab来显示Jupyter笔记本中任何已初始化对象的所有可能方法，如下所示:

I'm trying to use . + tab to display all the possible methods any initialized object in Jupyter notebook like this:

(用于上下文的列表对象的示例图像)

(example image of a list object for context)

，将不会显示任何内容.但是在内存中可以显示变量.

and none will show up. But in memory variables can be shown.

我正在从MacOS终端从具有以下版本的虚拟环境中启动Jupyter Notebook

I'm launching Jupyter Notebook from my MacOS terminal from a virtual environment with the following versions

jupyter==1.0.0
jupyter-client==5.3.1
jupyter-console==6.0.0
jupyter-core==4.5.0

当我使用tab时，如何配置Jupyter Notebook以显示所有可能的方法?

How can I configure Jupyter Notebook in order to show all possible methods when I use tab?

更新

ipython

显示

%config IPCompleter.greedy=True已设置，但仍然无法正常工作
pyreadline仍然无法工作
它可以处理列表，但是可以使用熊猫的空白数据框.df. + tab不能使用Axessubplot对象显示可能的方法.
此问题已在Linux发行版中复制，笔记本通过100％使用一个线程直到内核中忙碌，直到最终显示可能的方法为止.在MacOs中，它不会挂在内核繁忙"中，并且仅在您添加提示时才显示任何内容(例如df.h + tab将显示head和hist)

Upgraded to notebook==6.0.1 and still doesn't work
In the same environment, ipython displays methods when using tab
%config IPCompleter.greedy=True was set and still doesn't work
pyreadline installed still doesn't work
it worked with lists but with a pandas empty data frame df. + tab wont display possible methods neither with an Axessubplot object.
This issue was replicated in a linux distro and the notebook hangs in kernel busy by using one thread by 100% until it finally displays the possible methods. In MacOs it doesn't hang in 'kernel busy' and won't display anything only when you add a hint (like df.h + tab will show head and hist)

我发现这里讨论了这个问题自动填充功能不起作用

I found that this issue was discussed here Autocomplete not working

您应该将ipython版本降级为6.2.1通过在虚拟环境中运行:

You should downgrade your ipython version to 6.2.1by running in your virtual environment:

pip install ipython==6.2.1

，然后重新启动jupyter笔记本.现在，它应该显示任何对象的方法，包括像这样的熊猫和海生动物

and then restart the jupyter notebook. Now it should display the methods of any object including pandas and seaborn ones like this
