Integrating ROS with Pycharm

Hello every one,i have read [this](http://wiki.ros.org/IDEs), but could not find .desktop file and secondly after searching on this issue a little bit, one solution which I came across was that of changing the interpreter so I do not want to change the interpreter because there is already environment set for the pytorch and I do not want to change that, so can any one help me that how I will me able to run ROS from pycharm.

Regards.
