Spyder3 crash after updating python

[Artofantidote]

Hi, 

My Spyder3 crashed with this message after updating python to 3.6 with this http://ubuntuhandbook.org/index.php/2017/07/install-python-3-6-1-in-ubuntu-16-04-lts/ : Spyder crashed during last session.

If Spyder does not start at all and before submitting a bug report, please try to reset settings to defaults by running Spyder with the command line option '--reset':
python spyder --reset

Warning: this command will remove all your Spyder configuration files located in '/home/peok/.spyder2-py3').

If restoring the default settings does not help, please take the time to search for known bugs or discussions matching your situation before eventually creating a new issue here. Your feedback will always be greatly appreciated.

It doesn't work even after resetting or reinstalling.

I need some help thanks !
