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!

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

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

start the anaconda-navigator software,
locate the jedi package in my environment,
click the little checkbox on the right of jedi
under "Mark for specific version installation", choose 0.17.2

After restarting the kernel everything worked :)

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:

[IPKernelApp] ERROR | Exception in message handler: Traceback (most recent call last): File "D:\apps\miniconda\envs\pydata-book\lib\site-packages\ipykernel\kernelbase.py", line 265, in dispatch_shell yield gen.maybe_future(handler(stream, idents, msg)) File "D:\apps\miniconda\envs\pydata-book\lib\site-packages\tornado\gen.py", line 762, in run value = future.result() File "D:\apps\miniconda\envs\pydata-book\lib\site-packages\tornado\gen.py", line 234, in wrapper yielded = ctx_run(next, result) File "D:\apps\miniconda\envs\pydata-book\lib\site-packages\ipykernel\kernelbase.py", line 580, in complete_request matches = yield gen.maybe_future(self.do_complete(code, cursor_pos)) File "D:\apps\miniconda\envs\pydata-book\lib\site-packages\ipykernel\ipkernel.py", line 356, in do_complete return self._experimental_do_complete(code, cursor_pos) File "D:\apps\miniconda\envs\pydata-book\lib\site-packages\ipykernel\ipkernel.py", line 381, in _experimental_do_complete completions = list(_rectify_completions(code, raw_completions)) File "D:\apps\miniconda\envs\pydata-book\lib\site-packages\IPython\core\completer.py", line 484, in rectify_completions completions = list(completions) File "D:\apps\miniconda\envs\pydata-book\lib\site-packages\IPython\core\completer.py", line 1815, in completions for c in self._completions(text, offset, _timeout=self.jedi_compute_type_timeout/1000): File "D:\apps\miniconda\envs\pydata-book\lib\site-packages\IPython\core\completer.py", line 1858, in _completions matched_text, matches, matches_origin, jedi_matches = self._complete( File "D:\apps\miniconda\envs\pydata-book\lib\site-packages\IPython\core\completer.py", line 2026, in _complete completions = self._jedi_matches( File "D:\apps\miniconda\envs\pydata-book\lib\site-packages\IPython\core\completer.py", line 1369, in jedi_matches interpreter = jedi.Interpreter( File "D:\apps\miniconda\envs\pydata-book\lib\site-packages\jedi\api_init.py", line 725, in init super().init(code, environment=environment, TypeError: init() got an unexpected keyword argument 'column'

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

%config Completer.use_jedi = False

This command helps but we need to add it to all the notebooks again and again.

The answer from Sagnik above (Dec 20, 2020) works for me on Windows 10.

pip3 install jedi==0.17.2

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

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

pip3 install jedi==0.17.2

I had the same issue when I was using miniconda, I switched to anaconda and that seems to have solved the issue. PS. I had tried everything I could find on the net but nothing resolved it except for switching to anaconda.

Creating a new env variable helped me to solve this problem.

Use environments.txt content in .conda as path.

The best fix I've found for this issue was to create a new Environment. If you are using Anaconda simply create a new environment to fix the issue. Sure you have to reinstall some libraries but its all worth it.

The workaround I found is to assign the intermediate result to a temporary variable.then in seperate cell, using tab on temporary variable for auto-completion.

temp = pd.Description

temp.TAB

you can add

%config IPCompleter.greedy=True

in the first box of your Jupyter Notebook.

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:

conda update conda
conda update --all

The solution was taken from here based on the error that I had in IPython in terminal after writing np.<tab>:

No such file or directory: '/home/user/miniconda3/lib/python'

In my case, after running pip install pyreadline, I needed to re-execute all the lines in Jupyter before the completion worked. I kept wondering why it worked for IPython but not Jupyter.

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
