I have an older code that I am trying to update to up-to-date -version of SfePy. The code has been running with the SfePy 2014.4. Now when updating to Anaconda, python 3.6 and SfePy 2018.1 the same script gives me the error message below. Is this a problem with my script or a bug in SfePy?
Thank you for you help! -Tuomas
