Newbie question: Pycharm is stuck with processes running: REPL Communication

I tried to execute my code in the console and this seems to result in pycharm geting stuck. I have releatively simple code that I'm trying to execute in the console

import pandas as pd
import numpy as np
from matplotlib import pyplot as plt

iris=pd.read_csv('iris.csv') #import iris




but when I hit execute selection in python console Pycharm always gets stuck, I see a process running endlessly (never stopping) called REPL communication. The code doesn't run. I have attached my interpreter configuration to this post




Maybe the csv file is so big it's simply taking time to process it all?




It seems like a known issue reported here


Please attach your logs and steps to reproduce the issue(if there are any) to the ticket.


Apologies for the inconvenience. 




Same issue here :/

Same with me.
I get a never ending "Waiting for Execution Result" for some simple code line. This only happens some times


For me, I'm using Django, and I had many `@property` that were computationally heavy in the class (several checked if a file existed in S3 for example). I removed the `@property` and the Python Console is suddenly fast. Not sure if this is related or could be a solution for someone else.
