I experienced this problem whilst running ipython console in the WinPython distribution. In my case the problem was fixed by installing pyreadline:
pip install pyreadline
Hope this works for you too.

I recently wrote a package which is on 1.2.9 but when trying to import it using pip install rolimons Python tries to import 1.2.9 which fails and moves on until version 1.1.3 which is the only version that doesn't error out.
Here is the error:

Can't be causing this error.
I have searched the documentation and found nothing like this error.
I have solved the problem by editing the file asyncio.py in tornado\platform adding:
import sys
if sys.platform == 'win32':
asyncio.set_event_loop_policy(asyncio.WindowsSelectorEventLoopPolicy())
I had the same error.
Which version of python do you use? mine was 3.8 then I changed to 3.6 and everything works correctly.
One question of this type is previously asked but is not very helpful. I am using version Python3.8 in Windows 10 OS. I am getting an error, KeyError: 'sapi5'. dont know why this error is occurring. Please have a look at the below code given . My code is-
import pyttsx3
engine = pyttsx3.init('sapi5')
voices = engine.getProperty('voices')
engine.setProperty('voices', voices[0].id)
The Error is quite big. can anyone help me?

my ipython notebook functionality stop working.
If I do
ipython notebook
the console just hangs forever with no debug output.
I have already tried reinstalling ipython but no success.
Also, if I start normal ipython everything seems fine.
Does anybody have a clue how to solve this? I suspect some lock file is still there but how can I find out what is exactly going wrong?
also if I force interrupt I get the following stack trace

I had the same problem in Linux/Ubuntu. This also hanged spyder.
Workaround for me:
(1) Look at host name of computer
cat /etc/hostname
which gives e.g. my-laptop
(2) Ensure that /etc/hosts contains the following entry
127.0.0.1 my-laptop my-laptop.local
because ipython looks for a 'local' extension too.
And fire up again ipython notebook or spyder. This worked for me for spyder, when it was hanging at:
PUBLIC_IPS = socket.gethostbyname_ex(socket.gethostname() + '.local')[2]

I tried to upgrade ipython to the latest version using pip, which did not help. Any solution or workaround is very much welcomed.
IPython store history in a profile generally in ~/.ipython/profile_default/history.sqlite. There seem to be a disk error reading/writting to it.
Check the permissions of the file/folders, if necessary delete the file.
I solved it by set c.NotebookNotary.db_file = u':memory:' in jupyter configure file ~/.jupyter/jupyter_notebook_config.py
