I am new to Python language programming. I found that we can have auto completion on Jupyter notebook. I found this suggestion:
"The auto-completion with Jupyter Notebook is so weak, even with hinterland extension. Thanks for the idea of deep-learning-based code auto-completion. I developed a Jupyter Notebook Extension based on TabNine which provides code auto-completion based on Deep Learning. Here's the Github link of my work: jupyter-tabnine.
It's available on pypi index now. Simply issue following commands, then enjoy it:)
pip3 install jupyter-tabnine,
jupyter nbextension install --py jupyter_tabnine,
jupyter nbextension enable --py jupyter_tabnine,
jupyter serverextension enable --py jupyter_tabnine"
I did 4 steps installation and it looked installed well. However, when I tried using Jupyter notebook its auto completion didn't work. Basically my question is please help how to get auto completion on Jupiter notebook? Thank you very much.
Press tab twice while you are writing your code and the autocomplete tab will show for you. Just select one and press enter
After installing Nbextensions, go to Nbextensions in jupyter notebook, tick on Hinterland. Then reopen your jupyter notebook.

Hi I am using virtual studio and running the command on Jupiter notebook.
But this error happens.
"Failed to find a kernelspec to use for ipykernel launch"
Why can't I execute the command this time?
I had a similar situation. I was trying to switch from Anaconda to VS Code to run jupyter notebooks. Installed the extension for jupyter notebook and every time I tried creating an empty notebook and basic commands failed to run. On the top right corner, I noticed that the kernel just showed Busy. If you click on that it would ask for a kernel.
I was able to get it working after I installed the python extension on vscode.. not sure if this is the best approach though!!
You need to install the Python libraries Jupyter and ipykernel. On my VS Code editor, a prompt came up saying that ipykernel is missing, and clicking the "install" button would solve it.
I ran some jupyter notebook using VSCode. However, VSCode created some 'Python Interactive' environment which appears in my Jupyter Notebook. How do I remove them?
Sorry that's a bug in the python extension.
To delete them you can follow the directions here:
remove kernel on jupyter notebook
They're just json files in a directory that Jupyter maintains. The VS Code python extension created them to get our kernel to work.
If you still see these after deleting using jupyter kernelspec uninstall unwanted-kernal, you can clear these by uninstalling and then reinstalling your Jupyter extension in VSCode.
In VSCode, click the 'extensions' icon, then search 'Jupyter'. Uninstall it. Then install it.

I am trying to launch a Jupyter notebook using anaconda prompt. The browser session opens but no contents are visible on the page.
Does anyone have any idea how to mitigate this?
Screenshot of Anaconda Prompt:
Please refer to https://github.com/jupyter/notebook/issues/4467
I encounter similar trouble. So I just do 3 steps:
(1) uninstall Jupyter Notebook 5.7.6
conda uninstall notebook
(2) install old version
conda install notebook=5.7.4
(3) After lauching Jupyter Notebook 5.7.4
Press CTRL+R or CTRL+Shift+R to clear the cache
Then Jupyter Notebook works normally now.
Hope it's helpful to you.
I have created a free ubuntu instances on AWS ec2. I have installed jupyter notebook using command pip install jupyter. Please refer the screen shot showing
But while I'm trying to run jupyter notebook or jupyter notebook --generate-config, I'm getting error message as Command 'jupyter' not found. Can you please help me resolve this issue?
I use Jupyter too but I installed it completely different. You can install Anaconda3 which is used for python very often. From there, you can open the Anaconda3 prompt and use the simple command jupyter notebook to open it.
I tried without success to install some extensions to jupyter notebook and can't figure out how to do it.
So basically I would like to have pep8 code checking in my notebook.
I checked this post:
Verifying PEP8 in iPython notebook code
However %install_ext is deprecated so instead I used
jupyter nbextension install https://raw.githubusercontent.com/SiggyF/notebooks/master/pep8_magic.py --user
So I get:
Copying: /tmp/tmpw74yl7m2/pep8_magic.py -> /home/louis/.local/share/jupyter/nbextensions/pep8_magic.py
To initialize this nbextension in the browser every time the notebook (or other app) loads:
jupyter nbextension enable <the entry point> --user
From now on I could not get it working.
I tried:
~$ jupyter nbextension enable pep8_magic.py --user
Enabling notebook extension pep8_magic.py...
- Validating: problems found:
- require? X pep8_magic.py
Without success.
Can someone explain a simple method to get it working and what I missed about jupyter extensions ?
Thank you !
I manually copied the file from the link and then added to /.ipython/extensions (or /nbextensions) and loaded in the notebook: %load_ext pep8_magic
Currently testing but looks fine to me
