Error in ipython console "Exception [WinError 995] The I/O operation has been aborted"

Question

I have installed python 3.8.5 and in ipython 7.19.0 via Anaconda installer on Windows 10 machine and I get the following error in Ipython when I import keras and then run ls or any other commands. It happens when I import other commands or run other commands. Can anybody propose any solution? Is this to do with latest python or Ipython? Or something else.

Answer 1

It seems to be a bug in the ipython prompt toolkit (version >= 3)

Try doing this for your environment:

conda install prompt-toolkit~=2.0

Generally we can fix this by doing something like this:

py -m pip install -U prompt-toolkit~=2.0

If that does not seem to work, there is an extensive discussion of the bug here with a few other solutions: https://github.com/prompt-toolkit/python-prompt-toolkit/issues/1023#issue-534396318
