. + tab AutoComplete not working in Jupyter Notebook

问题

So out of nowhere I seemingly cannot autocomplete methods using . + Tab in Jupyter Notebook.

Currently running Jupyter 6.0.1

I've tried the following with no success:

$ sudo easy_install readline

conda install -c anaconda jedi & updated conda

and the following

pip install pyreadline

thanks!
