I tried to run the BEopt with one of the epw files from "weather-shift" and it is generating an error. The same file can be easily opened in DView and used in EnergyPlus. The error statement generated by BEopt is :

10/21/2018 11:02 PM: 1.xml: Warning: Weather data supplied in the xml file is inconsistent with the weather file and will be overridden.

10/21/2018 11:02 PM: 1.xml: Traceback (most recent call last):

10/21/2018 11:02 PM: 1.xml: IndexError: list index out of range

Does anybody have any suggestion to solve this problem?

BEopt requires an EPW with exactly 8760 hourly data -- it does not support all the flexibility that EnergyPlus/DView do. If you think your weather file meets that criterion, please upload the file and we can take a look.
