Spyder: Spyder has encountered a problem and automatically closes after few seconds when launching from navigator

[SuMaNong]

Problem Description

Just as title said, Spyder has encountered an internal problem. Meanwhile, Spyder freezes in "connecting to kernel". Then after few seconds, it automatically closes. I have uninstalled and reinstalled Anaconda Navigator and updated them (both Anaconda Navigator and Spyder) but it doesn't work. Unfortunately, I restarted my computer and it also doesn't work. I have tried many methods from Github, but all of them do not work. Now, I have no idea and have to seek help here.

What steps will reproduce the problem?

1. click 'launch' in Anaconda Navigator.
2. problem occurred.

Paste Traceback/Error Below (if applicable)

terminal input 'spyder':
Fatal Python error: Cannot recover from stack overflow.

Any help please? T-T

[dalthviz]

Hi @SuMaNong I think this is a duplicate of #6335

[ccordoba12]

Oh yeah, it is. Thanks @dalthviz!

@SuMaNong, to fix it you need to update Python to version 3.6.5 by running in Terminal.app

conda update python

[SuMaNong]

Oh, WoW, THANK YOU VERY MUCH!!!!!!

[ccordoba12]

You were lucky: 3.6.5 was released just two days ago :-)

[SuMaNong]

Yeah! I am lucky for your help, too!
