error when running example dataset(KeyError: 'SIZE_X')

[jinyuanchun]

Hello there,
I am following the instructions here to install ficture and try to run the example dataset. But I ran into error when it tries to load the file it generated in earlier step.

Below is the full log, could someone help with this? Any advise would be appreciated!

I'm sorry that I don't quite see how this could happen, it seems that the only issue is that the header of the final pixel level output is wrong. could you show me the command that you ran?
