PyCharm hanging for a long time in iPython console with big data

Question

I\'ve seen some reports PyCharm is slow but I\'m having an issue that seems that\'s too slow even compared to normal operation.

I have a big set of data in a pandas data

Answer 1

I have been facing the same issue for a long time as well: PyCharm debugging is extremely slow when using large pandas dataframes. If I want to view the contents of a dataframe in the Watches is often gives me a time out after waiting for minutes, so I basically stopped using the debug when working with dataframes

What I just found however, it that under

Files -> Settinggs -> Build, Execution, Deployment -> Python Debugger

You have to switch on the "Gevent Compatible" flag

I also have switched on all the other flags in this window (Collect rum-time types information, attach subprocess, and PyQt compatible). But the Gevent compatible flag really does the job for me: it suddenly instantanuously gives me the dataframe contents in the debugger watches.

I am using PyCharm verion 2016.2.3
