I have a code that takes data in .txt format and converts it to .ply format, after that it performs some operations on it. when I run the code it shows me the given error! please help me fix that error.
the code:
def convert_pc2ply(anno_path, save_path):
data_list = []
for f in glob.glob(join(anno_path, '*.txt')):
class_name = os.path.basename(f).split('_')[0]
if class_name not in gt_class:
class_name = 'clutter'
pc = pd.read_csv(f, header=None, delim_whitespace=True).values
labels = np.ones((pc.shape[0], 1)) * gt_class2label[class_name]
data_list.append(np.concatenate([pc, labels], axis=1)) # Nx7
pc_label = np.concatenate((data_list, [0]))
xyz_min = np.amin(pc_label, axis=0)[0:3]
pc_label[:, 0:3] -= xyz_min
xyz = pc_label[:, :3].astype(np.float32)
colors = pc_label[:, 3:6].astype(np.uint8)
labels = pc_label[:, 6].astype(np.uint8)
write_ply(save_path, (xyz, colors, labels), ['x', 'y', 'z', 'red', 'green', 'blue', 'class'])
the error:

I don't understand the error or where it came from to try!
