Train GIGA

[buaawzh]

When I trained the GIGA, I have this problem

File "/home/wzh/GIGA/src/vgn/dataset_voxel.py", line 98, in read_occ
path_idx = torch.randint(high=len(occ_paths), size=(1,), dtype=int).item()
RuntimeError: random_ expects 'from' to be less than 'to', but got from=0 >= to=0

I don't know what cause this error.
Maybe I fail to save the valid occupancy data?

I think it means the length of occ_paths is 0. And occ_paths is from here. Maybe you should check the directory to see if the occupancy data is saved.
