I just installed Anaconda. I already had Spyder 3.0.0 installed on my Windows 8.1 (64 bit). I also already had Python 3.4 installed. But, after installing Anaconda, I went into Preferences and pointed the Python executable to the Anaconda3 folder to utilize the 3.5 version. But when I started up Spyder again, got the following error:
An error ocurred while starting the kernel

Any ideas?
Suggestion:
rename your directory "C:\WinPython-64bit-3.4.4.2" in "C:\WinPython-64bit-3.4.4.2bis"
relaunch your Anaconda Spyder
if it doesn't help, rename it back to "C:\WinPython-64bit-3.4.4.2"

A while back, I upgraded my python version via brew to 3.9.0 and now, whenever I try to start Jupiter notebook, I get this error:

I've tried completely uninstalling and reinstalling jupiter to no avail. I've also tried reinstalling the zmq module that seems to be a part of this error chain. My thought is that there must be some component that's avoiding my uninstalls that needs to be fixed/updated, but I'm not sure what it could be.
I'm also running MacOS 10.13.6. I notice it states that one of these modules was built for Mac OS X 10.15. Could this instead be the issue?
The answer provided in this link worked for me:
Cannot run jupyter everywhere (terminal, anaconda distributer) Mac os 10.12.6
"downgraded pyzmq to 20.0.0 and it worked fine. pip install pyzmq==20.0.0
I believe the issue is in pyzmq's cython packaging - and should be raised as a bug to them."
The bug has been raised and is expected to be fixed by release 21.0.2
I got a problem with running jupyter in the terminal.

I was trying to use Anaconda and got the same issue
For me, it seems to be something wrong with path...
Please help me to resolve it or give a hint of what to do
I'm seeing the exact same issue - seems the zmq package has a /cython/ in it with incompatible references. Is it not using cython from the site-packages? I've tried reinstalling cython, pyzmq, and all the jupyter modules with no joy yet.
EDIT - I downgraded pyzmq to 20.0.0 and it worked fine.
pip install pyzmq==20.0.0
I believe the issue is in pyzmq's cython packaging - and should be raised as a bug to them.
I found 0 topics about this issue for Windows, only for Ubuntu, MAc etc.
When I try to install any package via Pycharm, e.g. urllib, matplotlib, heidi, I get the exact same error message as below.
Project interpreter is Anaconda Python 3.7.
Any idea how this can solved?

Edit: with pip I have only problem with matplotlib, which is another topic:
Cannot install matplotlib. Fatal error LNK1181, Visual Studio fail
Simply went into packages folder and deleted matplotlib package manually because could not make it display graphs in Jupyter (didnt try in Pycharm). Trying to reinstall it now, hopefully it will fix the issue.
To install packages whithin anaconda environment under Windows10, you should use "Anaconda prompt" (find it in win menu)
It starts (Base) venv by default and installs packages in it. Therefore using Python interpreter distributed with Anaconda you will be able to import them with no side actions.
Besides matplotlib is installed there by default

I am using the full Anaconda distribution, and although I have created an environment I did this from the root Anaconda env (i.e. /Users/me/anaconda3) and not within an env.
Some quick details that may help with figuring out the problem:
python --version = Python 3.6.1 :: Anaconda 4.4.0 (x86_64)
OS is MacOS Sierra 10.12.6
I don't know whether the same thing that is causing the KeyError: PYTHONPATH is also causing jupyter notebook to fail.
It seems that pyzmq is the problem. Run pip install pyzmq --upgrade or pip unistall pyzmq & pip install pyzmq to make sure you're on the latest version of it.

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.
