__Singleton instance has no attribute...

[josauder]

I'm getting an error during "Generate 3D Data" command -

__Singleton instance has no attribute 'floorheight_min'

from building_generation/Main.py, line 65 or so...

floorheight=np.random.uniform(singleton.floorheight_min,singleton.floorheight_max)

I thought maybe the 'np' was the problem, but I removed it and still got an error.

The building configuration file looks fine:

building_generation.conf: {"roofheight_min": 0.03, "scalefactor_min_house": 0.4, "floorheight_min": 0.03, "prob_ledge": 0.5, "diffuse_iterations": 72, "windowheight_max_not_house": 0, "house_height": 0.15, "windowdist_max_not_house": 0.03, "diffuse_power": 1.8, "floorheight_max": 0.04, "scalefactor_max_not_house": 0.95, "windowheight_min": 0.015, "offset": 0.03, "ledgefactor_min": 1.01, "windowdist_min_house": 0.01, "windowwidth_min": 0.013, "scalefactor_max_house": 0.7, "scalefactor_min_not_house": 0.7, "ledgefactor_max": 1.05, "windowwidth_max": 0.025, "windowdist_min_not_house": 0, "windowdist_max_house": 0.03, "windowheight_max_house": 0.027, "roofheight_max": 0.07}

Command line I'm using to run:

python2.7 GUI.py

josauder: An instance of singleton is not killed when the program fails- perhaps I should move the kill call from the actual steps to the UI

Hello,

Upon further investigation, I found that commenting out the line:

    plt.show()

from polygons/main.py

fixed that particular problem. The image was being displayed properly in a separate window, but the program never seemed to return from that call correctly.
