an issue about visualizing floorplane

[godhj93]

Hi, I am testing the Structured3D dataset for my research.

so far, I have downloaded the dataset and am trying to visualize it.

wireframe and plane work well with the command as follows:

python visualize_3d.py --path /media/hj/One\ Touch/Structured3D_Dataset/Structured3D --scene 00000 --type wireframe

python visualize_3d.py --path /media/hj/One\ Touch/Structured3D_Dataset/Structured3D --scene 00000 --type plane

but when i run the code with floorplane argment following issue happens

(test) hj@lab:~/Projects/3dmap/Structured3D$ python visualize_3d.py --path /media/hj/One\ Touch/Structured3D_Dataset/Structured3D --scene 00000 --type floorplan

    concatenate([asarray(t.exterior)[:, :2]] +
IndexError: too many indices for array: array is 0-dimensional, but 2 were indexed

Is there any solution?

Thanks

It seems you use a higher version of shapely, please try to downgrade it.

Cool, shapely 1.8.5 works
