What do you recommend guys for this error when I type in console ipython notebook and got

I installed ipython notebook with pip and really I don't know what is going on.

Bill

I've tried every single answer here and none of them fix my ModuleNotFoundError: No module named 'notebook.notebookapp' error when trying to run python manage.py shell_plus --notebook even though the notebook (jupyter notebook) seems to run fine otherwise... – Harold

Answer 1

For 4.0 and above You need to install the notebook app separately from https://github.com/jupyter/notebook

pip install jupyter

Eohippus

Correct. pip install jupyter is enough to fix the error and launch the notebook. – Legman

Or pip3 install jupyter if you're on a system where Python 3 is the default – Disgrace

If ipyton notebook <notebook> doesn't work for you, @meduz mentioned in a comment below that running jupyter notebook <notebook may work instead. That resolved the issue for me. – Brittani

I have different python versions and pip3.6 install jupyter did the job – Hahnke

i get same error even after doing pip install jupyter – Empery

conda install jupyter will install latest jupyter along with other required dependencies

Anaconda installation users only. – Resa

Answer 3

This two commands will fix most problems for you:

sudo pip install --upgrade setuptools pip
sudo pip install --upgrade "ipython[all]"

Answer 4

I got the same problem when upgrading ipython. This is a bug linked to the latest 4 version, I recommend you switch back to the stable version 3.2.1:

pip uninstall -y ipython
pip install ipython==3.2.1

• note: the -y option indicates "yes I want to uninstall" with no interaction
• note 2: possible duplicate in ipython server can't launch: No module named notebook.notebookapp

Superpose

Works like a charm, but I additionally had to upgrade pip (sudo pip install -U pip) and a few packages via pip. – Author

See other answer: pip install jupyter. – Tailor

As @joeh said, it is recommended to upgrade to jupyter and to use the jupyter notebook command instead of ipython notebook one. – Superpose

disclaimer: this answer was given in 2015 - please regard this as a solution which relevance is mainly historical :-) – Superpose

Agree with above. Unless you are using an old Python version then this will likely cause many issues. – Harold

Answer 5

this is what it worked for me:

pip install -U notebook

Kolnos

Answer 6

if you are using python version 2

pip install jupyter

in case using python 3.x

pip3 install jupyter

to be on the safe side also check that notebook module is installed or not

pip install notebook

or

pip3 install notebok

Answer 7

Go to the path that will appear for you for example: C:\Users\Soft\anaconda3\Scripts\jupyter-notebook-script.py and change notebook.notebookapp to just notebook.app. This worked for me.

Suckow

Answer 8

Just run

python manage.py shell_plus  --lab

and if you are running inside a docker container:

python manage.py shell_plus  --lab -- --allow-root --no-browser  --ServerApp.ip 0.0.0.0

Answer 10

Install Specific Version:

pip install jupyter

Upgrade jupyter

sudo pip3 install --upgrade jupyter

Getting Dependency Error in Window 10 Use code: easy_install instead of pip install

easy_install jupyter 

Upgrade using easy install

sudo easy_install --upgrade  jupyter

On OSX System to install Module: Use code: brew install instead of pip install

brew install jupyter 

Without Using Pip :

 sudo apt-get install -y jupyter 

On CentOS7 or Linux Fedora:

yum -y install jupyter 

Or on Fedora try

sudo dnf install jupyter 

Command if Homebrew screws up your path on macOS:

python -m pip install jupyter 

For Python3 MacOs Homebrew screws

python3 -m pip install jupyter

Verify module from list MacOs

pip freeze | grep  jupyter

For Execute on Anaconda as your python package manager

 conda install -c anaconda jupyter 

Kurman

Answer 11

from the env path C:\Users\awatim\envs\ds2\Scripts\jupyter-notebook-script.py

Replacing notebook.notebookapp to just notebook.app is worked for me also

as above Abdelrahman Elaraby has mentioned same.

Answer 12

NoModuleFoundError: notebook.notebookapp

It is because you imported the notebookapp module from the wrong folder, the notebookapp module you are trying to use is not in the notebook folder.

Go to the file location where the jupyter-notebook-script.py and open it in VS code. Now run this file and check the same error you occurred when trying to open the Jupyter Notebook from cmd prompt or from anything.

If the same error occurs then go to this file location C:\ProgramData\anaconda3 and search the { notebookapp } python now to go to the file location by cliking the left click on that file and you will get the option that is open file location now click on that.

You will directed to the location of that file. Now the most important, find out the folder in which this ( notebookapp ) file is stored.

In my case it was found in the nbclassic folder.

Open the file/script jupyter-notebook-script.py in vs code or any IDE and change the code like below. notebook changes to nbclassic

Before updating

---

import re
import sys

from notebook.notebookapp import main

if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0])
    sys.exit(main())

---

After Updating

---

import re
import sys

from nbclassic.notebookapp import main

if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0])
    sys.exit(main())

---

Change the code like that in my case it is found in nbclassic folder thats why i am importing from that.

from nbclassic.notebookapp import main

This will definitely work if you have the same error.
