in dataset.py, when preparing data, the ground truth boxes are filtered with point cloud range. You may comment this.
Or do a clean-up with boxes outside the pointcloud range when create a pickle train file.

Hi, @vatsal-shah, I met the same error as yours. I also Nuscenes to the KITTI format using their script.
But I found that there are some label file is empty in train set and val set, just del the empty label file name from the ImageSet/train.txt or val.txt.
It works!

We will re-sample a scene if we find there doesn't exist any objects in current scene. See #340.

Hi @PengfeiMa ,I met the same error as yours, how to check if the label file is empty or not ?

@GYE19970220 Open the label file, if there is nothing, then delete the file name from the ImageSet/train.txt or val.txt.

As nonsense as it is, I didn't find any other way than really remove it from the train.txt file. Additionally it is not super easy to identify which label is wrong since it does not crash right away. My brute force fix is adding to get_infos
loop this
try:
annotations['bbox'] = np.concatenate([obj.box2d.reshape(1, 4) for obj in obj_list], axis=0)
except:
print(sample_idx)
file = open("/home/raghav/code/UDA/DA-IA-SSD/data/kitti/ImageSets/val.txt", "r")
lines = file.readlines()
new_lines = []
for line in lines:
if sample_idx not in line.strip():
new_lines.append(line)
file.close()
file = open("/home/raghav/code/UDA/DA-IA-SSD/data/kitti/ImageSets/val.txt", "w")
file.writelines(new_lines)
file.close()
