I am using Windows 10 and Python 3.5.2. I installed the package, along with its dependencies, via: pip3 install "ipython[notebook]" --upgrade
The aforementioned process proceeded without incident but I am confused why the issue has appeared.
Thanks.
It seems to be an issue with pyzmq 15.3. Installing a previous version worked for me:
pip install pyzmq==15.2

Good luck!

Conda Environment Info:
jupyter-client:7.1.2
jupyter_client:5.3.1
python:3.8.0
I tried This Github Issue and followed the steps of This stackoverflow post.
Reproduction steps:
Install anaconda3
create conda env with conda create -n env python=3.8
conda install -c anaconda jupyter
jupyter notebook
You have apparently anaconda installed, but also a seperate python installation, see how both C:\Users\sk_np\AppData\Roaming\Python\Python38 and G:\anaconda show up in your traceback. This is probably causing the issue due to inconsistencies in the packages. The simplest step, and the one that will save you a lot of headache in the future, would be to uninstall the python that you have at
C:\Users\sk_np\AppData\Roaming\Python\Python38
Additionally, run in your anaconda prompt (from which you tried to start jupyter)
jupyter kernelspec list
and then remove the kernel that is at C:\Users\sk_np\AppData\Roaming\Python\Python38 with
jupyter kernelspec remove <kernelName>
SOLVED: the solution was I needed zlib1g-dev
This is the error pyenv produces

I have found nothing on this when googling and have no idea what is going on.
the steps that I have done are, first installing the pyenv installer and running that script then trying to run (pyenv install -v 3.9.0)
the system does have python3.8 installed and pyenv does seem to know about it
but it still will not let me install 3.9.0
EDIT: I should also throw in that in order to let pyenv know about the system version of python I did this (sudo ln -s /usr/bin/python3 /usr/bin/python).
Another thing is I also tried installing 3.9.0 with a tool called asdf and that resulted in the same error
EDIT2: It seems like im missing zlib from the traceback but Im on ubuntu and do have zlib1g installed and from what I looked up thats what zlib is on ubuntu 20.04 im going to try and find more info on the zlib and see if I need to install something else
I had a similar problem trying to install Python 3.8 with asdf (which uses the same backend as pyenv) on WSL2/Ubutnu18, and installing zlib1g-dev was not enough to solve it as stated by the question's author.
Therefore, as a more general solution, I have found that installing all dependencies recommended by pyenv for Ubuntu did solve the problem for asdf (and I suspect for pyenv as well). The dependencies for different OS can be found here: https://github.com/pyenv/pyenv/wiki#suggested-build-environment
I hope this is useful for others!

I recently installed Jupyter on a new computer and after trying with and without virtualenv, I receive the following errors related to the threading module. This error prevents the notebook from either (1) opening or (2) starting the kernel.
Error upon opening python -m notebook. Notebook doesn't open successfully.

Seeing as threading is a built-in module, I cannot update it. Again, this result is identical using the normal site-packages installation and a clean virtualenv installation.
I found that this error was caused because a file named threading.py (not related to the built-in module) existed in a subdirectory of my home directory. If I launched the notebook from any directory where the file was anywhere in the directory tree below my current directory, I would receive this error.
The solution is to launch the notebook in a directory where a naming conflict with the built-in threading does not exist.
The odd thing is that if I import threading in a Python shell in the same directories where the failures occurred and run dir(threading), it picks up the correct package. Why does Jupyter treat this differently?

SyntaxError: invalid syntax
Note: pip version is 18.1
I figured it out. The syntax - u"".join is not supported in python3.2.
pip3(which was same as pip3.2) while running the scripts for installing boto3 faced the syntax and threw the exception.
I installed python 3.6 and on running "pip3.6 install boto3", it worked.
Note: My python project is new and small one, so changing from python3.2 to python3.6 did not affect much, but with large or existing project this may not be feasible. Just want anyone who may face the situation to know the reason for this issue.
