I am having issues launching Jupyter Notebook. I have tried to do it two ways and seem to get errors.
1 - Launching from the Anaconda Prompt using the command jupyter notebook or directly choosing from the Anaconda menu
I get the following:
(base) C:\Users\metni>jupyter notebook
Traceback (most recent call last):

Jupyter notebook format depends on the jsonschema package:
https://pypi.python.org/pypi/jsonschema
Please install it first.
2 - Launching from the command line with the same command
I get the following:
C:\Users\metni>jupyter notebook
Traceback (most recent call last):
File "C:\Users\metni\anaconda3\Scripts\jupyter-notebook-script.py", line 6, in <module>

It seems like this is referring to a package called jsonschema which is not installed apparently, but running a pip install jsonschema does not solve the problem for me...
In the answer above I also have two two commands but they are a bit different
source /opt/anaconda/bin/activate root
and then
jupyter notebook
It seems like you have to go into your anaconda directory then bin, then you can
"activate root"
It also looks like you need to install some other dependencies for jupyter to run. Where is says
Jupyter notebook format depends on the jsonschema package:
https://pypi.python.org/pypi/jsonschema
Please install it first.
So if the above doesn't work try installing the other dependency and try again
Based on this answer from a similar question, I managed to solve the problem by running these two commands:
conda update -n root conda
conda update --all
I thus updated all packages, and the notebook is now launching.

There was another thread about this same problem here: Can't use Jupyter Notebook: jsonschema apparently missing, however, after following all the steps in the solution the error persist. If anyone might be able to provide a possible solution, I'd greatly appreciate it.
You need to install jupyter notebook seperately in code.
description is given: Jupyter notebook
So I ended up uninstalling and reinstalling Anaconda and VS Code and it fixed the problem.
EDIT: Akshat Zala helped me find the underlying problem. I was trying to run the Interactive Window in a brand new Anaconda environment. This means I did not have Jupyter Notebook installed on it yet, therefore, the interactive window would not work. I fixed this issue by activating the conda environment then running the command 'conda install -c conda-forge notebook'.
An import error occurs when trying to run jupyter notebook
I'm trying to run jupyter notebook using anaconda (git bash platform), and as I type in jupyter notebook, an import error occurs every time. I tried to lauch it inside an environment, but the same error occured.
$ jupyter notebook

EDITED
After reinstalling pyzmq (and I tried reinstalling conda too), the following error occurs:

I found a similar issue open on GitHub for zmq. The recommendation by GitHub user harsh23tyagi that seems to work for most is to run the following:
pip uninstall pyzmq
pip install pyzmq
Working with conda env, jupyter notebook worked in (base) env but gave the .libzmq error in (my_env).
To be able to run notebooks from my_env, this worked for me :
pip uninstall pyzmq
pip install pyzmq==20 (no version for pyzmq didn't fix the issue for me)
It seems that updating pyzmq to the latest version fixes this problem for me.
conda install pyzmq=22
Today I installed python 3.7 from apt-get to try out the new dataclasses module. I installed it seperately because python3.6 wasn't upgradeable to 3.7.
When I type: python3.7 --version, it gives me: >>> Python 3.7.0a2 as my current version.
The problem is that I can't seem to import dataclasses.
my import statement is: from dataclasses import dataclass as instructed here
This is the error message it's giving me:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'dataclasses'
Error in sys.excepthook:

ModuleNotFoundError: No module named 'apt_pkg'
Original exception was:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'dataclasses'
I even tried installing the dataclasses module with pip3: pip3 install dataclasses. Not sure if that's necessary though.
Any suggestion on what might be the problem?
[EDIT] Just tried it with a python3.6 console and it worked fine .. weird.
As suggested by #wim python3.7 -m venv venv_dir
This command will:
Use python3.7 to run the command
The -m flag tells the interpreter to run the next argument as a script
venv is a module, and because of the -m flag it will be run as a script
Finally, the venv_dir is given to the venv module as an argument which
this module will use to create a virtual environment directory at
Once this command is run now you'll have a nice sandbox for messing around/testing the dataclasses module.
To activate this virtual environment be sure to run source venv_dir/bin/activate before you begin. This command will run the script at venv_dir/bin/activate to set up the necessary environment variables and other things for you
To deactivate, simply run deactivate after activating
I had python pip installed and it was working fine but I did something wrong now it is broken.
Now when I execute pip command to install new packages, I get an error.
like if execute pip list then I get the below error.

I have the Anaconda distribution of Python 2.7 and I needed to install the Jupyter notebook package. During the installation process my computer turned off and after that I couldn't continue with the process. I tried to uninstall Jupyter and try installing it again, but I keep getting the same error:

What should I remove/add in order to make it work?
You need to install the python package simplegeneric. After you install it, you need to install the next package that you fail to import. Continue this process until you dont get any import errors.
