Problem running main_semantic3D

[sahar-github]

Hi I have a problem running the main_semantic3D.py. I followed the instructions as it was suggested. However, each time I run the routine, I see this error message, which I do not know why this happens? python main_Semantic3D.py --mode train --gpu 0 Load_pc_0: bildstein_station1_xyz_intensity_rgb Traceback (most recent call last): File "main_Semantic3D.py", line 349, in dataset = Semantic3D() File "main_Semantic3D.py", line 94, in init self.load_sub_sampled_clouds(cfg.sub_grid_size) File "main_Semantic3D.py", line 121, in load_sub_sampled_clouds sub_labels = data['class'] ValueError: no field of name class I would appreciate if you could give a hint, how can i solve this issue. PS, I am using your own dataset to only test the routine, for the first time.

Did you create the plyfiles correctly? It looks like your plyfiles don't have a class field. Line 116 reads in the plyfile and converts it to an array, but based on that error message your plyfiles don't have a class field. If you want to quickly look at the fields of a plyfile you can pip install plyfile and with that execute the following code:

from plyfile import PlyData
plytxt = '/path/to/plyfile.ply'
with open(plytxt, 'rb') as f:
    plydata = PlyData.read(f)
print(plydata.elements[0])

That should give you a list of the fields in the plyfile.
