Demand calculation: Error "alueError: operands could not be broadcast together with shapes (8760,) (8765,) () " about cityenergyanalyst HOT 5 CLOSED

Happy it worked!
Thanks for detailing the processes. We will still take a look at your weather file provided at #3368.

from cityenergyanalyst.

For the sake of completion, note that I have tested @lilaleu's weather file and it is read correctly by cea.utilities.epwreader.epw_reader (8760 rows). There does seem to be an extra column (index) but that shouldn't be a problem as CEA will in any case only use the columns it needs. So that was indeed not the issue (as demonstrated by the fact that the issue couldn't be replicated by @lilaleu's colleague).

In any case, it seems like the issue is resolved... for now?

@ShiZhongming have you seen that error before?

@lilaleu Please send the weather file causing this error. Compress your .epw file to .zip. and you can send via GitHub.

I think I have just solved the problem:
The error kept on occuring at the very end of my demand calculation (often at 6th last building). I tried to run the calculation on another computer. Therefore I copied all input- and output data except from demand files and ran the simulation on another computer. Same error again.

Asking a colleague to help me, she ran the simulations with the same original inputs (zone, typology and weather) from scrap (street-,sourrounding-,terrain-helper, archetypes mapper, Solar radiation, shedule maker,) and finally demand calculation. She could not reproduce the error, leaving me clueless. Then I tried the same: Simulation from scratch with my second computer using the CEA workflow functionalities and a modified yaml from the example workflows. This time the demand calculation ran through without any errors.

@ShiZhongming you probably refer to #3368 where the problem was a faulty weather file, causing errors in demand calculation. Eventhough this issue is already closed I will upload the problematic epw file there in case this might become of interest at a certain point.

For this case I suspect a whitespace in my windows user-name as the problem. I might seem like a bloody beginner with python stuff, which I am. Anyway I guess this could be a very "promising" reason for this problem. It wouldn't be my first time having trouble with Python based code because of this issue.
