Import error while trying to run jupyter 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
Traceback (most recent call last):

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

During handling of the above exception, another exception occurred:

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

I'm pretty sure that pip comes with python 3 and up. If you have troubles running only "pip" from the terminal i'd recommend you try: python -m pip ...

Try to use the 'Alternative instructions' from this post.
Hope this can help.

Jupyter Notebook error [duplicate]

I am not able to run the notebook in my browser. It does not appear. The console is giving me the following error. I have Anaconda installed. Any help would be highly appreciated. Thanks

I uninstalled pyzmq and re-installed it:
pip uninstall pyzmq
pip install pyzmq
This worked for me.
Note that you may also need to reinstall the Jupyter notebook to be compatible with the latest version of Python.

Python: pip is installed but not working in windows

I have installed python 3.6.0, you don't need to install pip manually if you are using python (>3.3). But When I am trying to access pip (pip --version), it throws me two errors which mainly relate to not finding the module.
Description is given below.
C:\Users\sharma6>pip --version
Traceback (most recent call last):
File "c:\python360\lib\site-packages\pip\_vendor\requests\packages\__init__.py", line 27, in <module>

import urllib3
ModuleNotFoundError: No module named 'urllib3'
Even when I import socket (>>>import socket)in python interpreter , It shows me "Can not found the module" error .
>>> import socket
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\python352\lib\socket.py", line 49, in <module>
import _socket
zipimport.ZipImportError: can't find module '_socket
Could someone tell me about the errors and how to resolve them because I need pip to work properly.

Add your all path in your system variable instead of adding in user variable.
It worked for me!!! :)

You should try to write
python -m pip --version
If this gives an error message, install pip by downloading get-pip.py from https://pip.pypa.io/en/stable/installing/ and install with
python get-pip.py
Installing with pip is then done by
python -m pip install [package name]

Jupyter install for Python 2.7 failed

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:
Traceback (most recent call last):

from simplegeneric import generic
ImportError: No module named simplegeneric
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.
