IPython and Jupyter autocomplete not working
PythonJupyter NotebookIpythonPython Problem Overview
I am very new to this and don't know why the autocomplete is not working. I tried modifying the iPython config file, installed readline, but still nothing.
Python Solutions
Solution 1 - Python
A possible reason a user may believe that autocomplete is not working may be that autocomplete is just taking too long. Circa 2020-11-27 this is particularly true for Pandas when operating with jedi in a Jupiter notebook environment.
The issue can be solved by using the following magic which deactivates jedi
%config Completer.use_jedi = False
For a deeper discussion follow the this thread and the links therein.
Solution 2 - Python
the current Ipython with the Jupyter notebook doesn't require jedi.. So you have to just uninstall it with the following command.
pip uninstall jedi --yes
Solution 3 - Python
Seems like installing a specific version of jedi worked for me:
!pip install --upgrade jedi==0.17.2
Solution 4 - Python
Solution 5 - Python
Ipython 6+ now has [jedi integration][1] built in.
update Ipython, and install jedi:
pip install ipython --upgrade
pip install jedi
If you are using Anaconda / conda:
$> conda update jupyter --update-dependencies
$> conda install jedi

Solution 6 - Python
just below the Python logo there is a button saying >not trusted
click on it and set it as trusted notebook.
Solution 7 - Python
I use JupyterLab 3.0.6. I have ipython 7.19.0 and jedi 0.18 installed. As @DaveHalter indicated, better than <% config Completer.use_jedi = False> is to use the previous version of the jedi
Solution 8 - Python
If you are using jedi=0.18 with ipython=7.19 try this in your environment:
pip install -U ipython==7.20
Solution 9 - Python
If you tried to install tabnine with the juptyerlab extension manager, type in
pip uninstall jupyterlab_tabnine
in a shell. When you still get the problem, delete the folder
%appdata%\Python\share\jupyter\labextensions\@tabnine\
this worked for me
Solution 10 - Python
install jupyter contrib nbextensions by running
pip install jupyter_contrib_nbextensions
Next install js and css file for jupyter by running
jupyter contrib nbextension install --user
and at the end run,
jupyter nbextension enable hinterland/hinterland
The output of last command will be
Enabling notebook extension hinterland/hinterland...
