I am trying to work with my Jupyter notebook. I have done so for the last 6 six years or so. Now I am getting the following error message:
Python Anaconda ImportError No module named menuinst.knownfolders
I checked several posts on the internet but nothing has helped: “conda install menuinst”. see here:
Python Anaconda ImportError No module named menuinst.knownfolders
I now have uninstalled and re-installed it three times but did not solve the issue.
When I go to my anaconda prompt and type in “jupyter notebook”, these are the error message I am getting:
C:\Users\User\anaconda3\lib\site-packages\setuptools\distutils_patch.py:25: UserWarning: Distutils was imported before Setuptools. This usage is discouraged and may exhibit undesirable behaviors or errors. Please use Setuptools' objects directly or at least import Setuptools first.

Just another piece of information, my anaconda prompt starts with (base) before it says C:\user\user>. Is that relevant or this issue?
You should try
conda remove zeromq
conda install zeromq
Solution-1
Please try to reinstall jupyter notebook from anaconda navigator it will definitely work
Solution-2
Please update jupyter notebook from anaconda prompt with below commands.
pip install notebook --upgrade
conda update notebook
I face the same issue..
1)Open anaconda prompt and type
conda list
2)Check terminado and
terminado 0.8.3
zeromq 4.3.2
3)In same anaconda prompt and check if python is working, type below code
python
if yes then
quit()
5)if no update python accordingly.
6)Type,
anaconda-navigator
This will open navigator and try to install jupyter notebook.

I am new to python and jupyter notebook and I am using windows. Recently I installed Anaconda Navigator 2.3.1 and the python verson 3.9.13 on my computer. After entering the command jupyter notebook on the command-line, my browser doesn't open jupyter notebook, instead that showing me this error message:

ImportError: cannot import name 'encodestring' from 'base64' (D:\Anaconda3\anaconda3\lib\base64.py)
I don't understand what should do now? And how to solve this issue! Please help..........
base64.encodestring was deprecated since python 3.1 and finally removed in 3.9
You can compare the official documentation for the base64 library for version 3.8 and 3.9
https://docs.python.org/3.8/library/base64.html
https://docs.python.org/3.9/library/base64.html
I'm not sure exactly how you installed anaconda navigator but i would suggest using the latest distribution of anaconda which includes navigator
This error is caused by nbformat. Check your nbformat with the command 'pip freeze', and look for the nbformat version. Most likely your version is anterior to 5.1.3.
Upgrade to that version with the following command:
pip3 install nbformat==5.1.3
or just 'pip install nbformat==5.1.3' ; depending on your configuration.
It should fix the issue.

The problem is:
I cannot launch applications like Spyder, Glueviz, Jupyter Notebook and JupyterLab from Anaconda.
I however can launch VS code but I suspect this is because I already had it previously installed.
However typing "jupyter notebook" or "jupyter lab" on the windows command prompt would launch it well, but this is not using Anaconda. I think this is because I have previously installed jupyter using pip.
First time I installed Anaconda, I checked the add to path option and a while later I had to uninstall it because I couldn't run python applications outside of anaconda. I checked my environment path variables and there are no references to Anaconda in it. So I guess this solution is out of the way.
This time when installing Anaconda, I made sure not to check the add to path option.
Sometimes, I would think this is an installation error, let's uninstall it then reinstall it, but that didn't work. I am using a freshly installed version of Anaconda now and the problem is persisting.
Here is an error that displays when I try to launch Spyder

Jupyter notebook format depends on the jsonschema package:
https://pypi.python.org/pypi/jsonschema
Please install it first.
The solution of the following link seems to be outdated, and is for python 2.7 only: Can't use Jupyter Notebook: jsonschema apparently missing.
Your Solution Worked for me. I had originally upgraded to jsonschema 3.20. I then downgraded to version jsonschema 3.02 and now my Jupyter notebook opens. Don't know why the higher version 3.20 creates the problem.
Well I also felt the same problem and my notebook or lab was also not opening. I found an answer in an website. I used the command conda install jsonschema==3.0.2 in the Anaconda Prompt and after installing my notebook and lab works fine again.
If you don't mind what version of anaconda you're using, downgrading anaconda to the 2020.02 version solved it for me (using conda install anaconda=2020.02).
This happend to me when I updated anaconda to the 2020.07 version using conda install anaconda=2020.07. I tried conda install jsonschema==3.0.2 as #user14080268 mentioned, but this caused the solving environment to fail and it went to look for incompatible packages, which then took for ever. Downgrading anaconda back to the version I initially had fixed the issue for me!
(of course, if you had a specific reason to update anaconda this might not be the best solution for you)
While setting up my new system, I am trying to run my notebook file on VS Code but as soon as I open VS Code it give me this error

I have installed all the plugins which were necessary, ran various commands, I also updated the notebook.
conda install notebook
I am using:
anaconda 3
vs code 1.26.1
windows 10
I cant start new notebooks or use an existing one either.
Please help, and let me know if any more information is required.
Check the required extensions installed in vscode.
install jupyter and ipython packages in your python venv using pip:
pip install jupyter
pip install ipython
If its still not working try to change the python kernal in the top right corner of ipynb notebook.
This is due to running jupyter without first activating the environment for Python 3.7. This was fixed in the 2018.12.0 release of the extension.
When it fails with this response you can uninstall conda and jupyter and install python from VS Code and then update. Don't necessarily install conda and jupyter.
I'm doing work in a conda environment. Today when I entered the environment, IPython failed to run, with the following error:

IPython is up to date:

It seems to be searching in the right place:
$ which ipython
~/miniconda3/envs/umiopy/bin/ipython
I'm using conda 4.3.14.
I've not changed anything in the environment but it's possible something has been updated by the system administrators (though it's hard to understand how that could affect my environment). What could be causing this problem? For similar errors on StackOverflow it seems like I'll need to update some module through conda.
If anyone ever experiences this issue, after some period of time, reinstalling iPython resulted in it working. I have no idea what broke it in the first place, and why reinstalling didn't help previously. Some sort of conda-related problem I suppose.
It's this simple:
conda remove ipython
conda install ipython
