Pycharm - Waiting for REPL response when python console using IPython

Response times in a PyCharm Python Console are unbearably slow when the console is configured to use IPython. This wasn't the case in a previous installation. When the Python Console is not configured to use IPython, and uses IDLE, it performs normally.

The poor response time seems to be linked to the REPL response function, as depicted in the image below. When the REPL response dialog completes, a background process continues to run for several minutes.

Since this was not a problem in a previous installation, the issue must be a result of a configuration change. However, the only thing I changed was to utilize a Conda env instead of a virtualenv.

Any ideas?

Posting my comment as an answer, I have tried it now for a few days and had 0 REPL hangups.

Ubuntu but should work on every machine.

Go to: File----> Settings---->Editor---->General---->Code Completion

Uncheck Rank completion suggestions based on Machine Learning

That's it. Happy Coding.

I am not sure if it is solved by jetbrains, for me, it just randomly starts even after 1-2 hrs of coding, I have tried every options found in Jet brains as well as Stack Overflow like checking and unchecking of 1,2 in combination as shown in image. Have experienced same with the code completion option as well,

These options might help:

Settings: File > Settings > Build, Execution, Deployment > Console

Ipython Setting option:
Run with Console option:

Today I had the same problem in Pycharm2019.3 with Python3.8. It may have been caused by using miniconda instead of the full anaconda installation, because after installing the ipython package (with -conda install ipython) the long REPL waiting times have dissappeared.
