TAB completion does not work in Jupyter Notebook but fine in iPython terminal

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

So far I had tried but failed,

1). run a command $ sudo easy_install readline,

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

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

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

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

Any help would be appreciated!

Solution 1:

It's a known issue and jedi is the problem. Try executing:

pip3 install jedi==0.17.2

https://github.com/jupyter/notebook/issues/2435

Solution 2:

My problem was in that I try to call autocomplete and import in the same cell. Because of imported thing does not initialized yet, autocomplete does not work.

All I need is call to the object in a new cell

UPD: or just run program once in the same cell to initialize imported

Solution 3:

I've just installed the latest JEDI then helped me to solve that issue, here's the command when using Anaconda:

conda install -c anaconda jedi

Or you might need to try this, copy this line on the top of your jupyter notebook:

%config Completer.use_jedi = False
