pycharm / conda integration

a couple of weeks ago, after the last upgrade of pycharm (professional edition) I started getting strange exit codes when importing some packages, specifically with keras and cntk backend

I tried downgrading, and tried reinstalling everything, but that did not help

Currently I'm staring PyCharm from the command line of an "anaconda prompt" window, which works

This seems to indicate that some environment variables have to be set

Does anyone know what settings need to be modified in PyCharm

btw, I'm using Windows-10 and the latest Anaconda with Python 3.6
