I had a similar issue and unfortunately cannot comment on a post, so am adding an easy solution that worked for me here. I use conda and conda list showed I was running jedi-0.18.0. I used the command conda install jedi==0.17.2. This quickly fixed the problem for my conda environment.
Additional note: I usually use jupyter-lab, and was not seeing the error messages generated. By switching to jupyter notebook, I saw the following error:

I highlighted a couple of the jedi messages, but this all reinforced it was a problem related to the version of jedi installed.

In my case I installed miniconda on Debian Linux and most likely had a problem with the previous Python that was included with Debian. The following lines solved my problem:

The solution was taken from <a href="https://github.com/conda/conda/issues/2240" rel="nofollow noreferrer">here</a> based on the error that I had in IPython in terminal after writing <code>np.&lt;tab&gt;</code>:

As the question was asked five years ago, the answer was likely different back then... but I want to add my two cents if anyone googles today: The answer by users Sagnik and more above worked for me.
One thing to add is that if running anaconda, you can do what I did: simply
<ul>
<li>start the anaconda-navigator software,</li>
<li>locate the jedi package in my environment,</li>
<li>click the little checkbox on the right of jedi</li>
<li>under &quot;Mark for specific version installation&quot;, choose 0.17.2</li>

I had the same issue under my conda virtual env in windows pc and downgrading the jedi to 0.17.2 version resolved the issue for me.
conda install jedi==0.17.2

TAB completion works fine in iPython terminal, but not in Firefox browser. 

So far I had tried but failed,

1). run a command <code>$ sudo easy_install readline</code>, 

then the .egg file was wrote in <code>/usr/local/lib/python2.7/dist-packages/readline-6.2.4.1-py2.7-linux-x86_64.egg,</code>

but TAB completion still doesn't work in Jupyter Notebook.

2). also tried to find locate the <code>ipython_notebook_config.py or ipython_config.py</code>, but failed.

I use Python 3.5 and iPython 4.0.0. and both are installed in Ubuntu 15.10 <code>/usr/share/anaconda3/bin/ipython</code>.

Any help would be appreciated!
