I have a problem during map validation for prediction purpose in QGIS 2.18 (validate the simulated map with the actual map). It showed an error message "error occurred while executing python code." I have added the screenshot and the message is yellow highlighted. Please, suggest me to overcome the problem.

Here, I have added the message (screen shot 2)that show simulated map geometry is different than reference map geometry. Please help me to solve the problem.
