I was doing my Logistic Regression with a Neural Network mindset when my submit button disappeared. I followed some instructions that told me to delete the notebook and that a fresh notebook would come back later, but the notebook completely disappeared. Every time I try to access it, I get a 404. I would much appreciate some help
If you deleted jupyter so try to install it from Anaconda Prompt with below command.
pip install ipykernel or conda install ipykernel
Once its completed then run below command..
python -m ipykernel install --user --name=NewEnv
Now run jupyter notebook from anaconda prompt it will work fine..

I hope everyone is doing good.
I installed Python a couple of days ago and then I install Anaconda3 2019.
Here is the screenshot of my programs installed on my system.
Now when I am trying to work on Jupyter, it is not opening. I tried to open Jupyter Notebook directly from the start (It showed a terminal opening and closing but after that, Localhost couldn't start). Later I tried through Anaconda Prompt and it gives me this Error.
conda list command shows that Jupyter library is present but I don't know where the problem lies.
These are the paths Environment variable has:
I'm a newbie and playing with python, Jupyter. I will appreciate it if anyone can help me to solve this issue I'm currently facing.
Thanks & Regards

Running Command conda install nb_conda produced this error:
Please follow the below steps:
conda activate <env_name>
conda install ipykernel
ipython kernel install --name <env_name> --user
If you are working on base environment, you can specify env_name as base.
Try running jupyter notebook using the command jupyter notebook
Hope this helps.
Go to your anaconda prompt and type the command conda install nb_conda.
Let this install and then try running the command jupyter notebook.
Let me know if this helps.
Issue: I get fatal error when I run jupyter notebook in cmd.exe as administratortor

uninstalled jupyter and installed anadonda (https://repo.continuum.io/archive/Anaconda3-5.0.1-Windows-x86_64.exe)
tried answer listed here but does not resolve the issue (Fatal error in launcher: Unable to create process using ""C:\Program Files (x86)\Python33\python.exe" "C:\Program Files (x86)\Python33\pip.exe"")

What worked for me was the command python -m notebook - I did not have Anaconda installed
I believe you need to open Jupyter notebooks by typing jupyter notebook in the anaconda prompt, not the regular windows command prompt.
For Windows users that have anaconda installed, try on Windows CMD/Powershell (better if you run it as admin):
(Assuming your environment is named "root")
activate root
jupyter notebook
Hope that helps
In my case, There was one redundant path of python3 added in the environment variable already and I was adding again.
I just removed that path and run jupyter notebook through command prompt and it worked perfectly.
I know this sounds strange ... But I ran:
python -m pip install jupyter
I did this inside my Anaconda (which I shouldn't have to do) and it installed jupyter... fixed the issue for me
Had the same problem what I did was
pip install jupyter
and then, just went ahead and typed
jupyter notebook
works like magic now
These command in cmd works:
activate root
jupyter notebook
The second command to open jupyter notebook is :
jupyter-notebook-script.py
I basically try to open notebooks with jupyter lab so what I have done is the following:
1.Right-click on any notebook select "open with" then select "choose another app"
Now select "look for another app in pc"
Go to the directory where your Anaconda Scripts are present. For me it's C:\ProgramData\Anaconda3\Scripts
Select "jupyter-notebook.exe" or "jupyter-lab.exe"
Now every notebook will open automatically just by hitting enter and no need to type the command again and again
For those ones who do not have anaconda
python -m jupyter notebook
I was using the Python37 installation from the Microsoft store, when I suddenly got the 'Fatal error in launcher: Unable to create process' error while trying to start the jupyter notebook. I actually tried every answer here, but with no succees.
The solution was to completely uninstall/delete everything Python/Jupyter related from AppData as well as the leftovers from my preceeding Anaconda installation and then go for a clean install from python.org.
I guess this is something we all have to do from time to time.
Check in to your Environment Variable Paths. If you had installed both Python(Python 2.x.x) or Python3(Python 3.x.x) you will have a problem running Scripts file of python, since you had duplicated install. Uninstall the redundant one.
If you had tried to fix it multiple times and nothing works, try re-install your Python. This save lives every time.
This problem is caused by your antivirus program because I suffered from the same issue, then I discovered that my antivirus software that I am using which is Avast was blocking python.exe file for some reasons that I do not understand.
So you should go to your antivirus settings and make an exception for python.exe file to unblock it.
Had the same problem and tried every suggestion here and in other forums.
In the end, removing the environment via conda remove and then creating it again worked. But I had to update conda via
conda update -n base -c defaults conda
and then start the notebook via jupyter notebook
I resolved this problem on Windows by running the Anaconda Prompt as Administrator, and then launching JupyterLab. Launching JupyterLab from the Anaconda Prompt with elevated privileges seems to have solved the issue entirely.
I really need your help, did extensive searching online but couldn't figure out, why I can't open the jupyter notebook from my terminal. If I type in
jupyter notebook
in the terminal, it says "Error executing Jupyter command 'notebook': [Errno 2] No such file or directory". So I checked if it's even installed with the command
jupyter --version
and the result was "4.3.0". Then I tried to change the directory to the path to the config-dir aswell as the data-dir, neither one did work. So I tried to uninstall with
pip uninstall jupyter
and I got the output "Cannot uninstall requirement jupyter, not installed". I tried to re-install it aswell with
pip install --upgrade --force-reinstall --no-cache-dir jupyter
but didn't work too.
Can anyone help? How can I delete everything related to python from my mac so I can install it from zero again?
Thanks for help! --batman
I am on a Ubuntu machine. I installed Jupyter Notebook using the following command.
sudo snap install jupyter
But Jupyter cannot find any of the installed python packages which were installed using terminal. I checked if jupyter and terminal are pointing to same python installation using this code.
import sys; print(sys.executable)
Terminal shows this output.
'/usr/bin/python3'
And Jupyter shows this one.
'/snap/jupyter/6/bin/python'
Now I want the jupyter to point the same installation path as the terminal shows. How can I do that?
your jupyter is not placed in default packages location due to installing it with snap. install jupyter with pip this way: pip install jupyter
if you dont have pip then download it. it usually is included in python package
