Problems executing train.py

[MinSheng8852]

Traceback (most recent call last): File "train.py", line 327, in train() File "train.py", line 99, in train train_data = DataGenerator(train_file, num_cols=args.data_dim) File "/home/3DFeatNet/data/datagenerator.py", line 21, in init self.load_metadata(filename) File "/home/3DFeatNet/data/datagenerator.py", line 34, in load_metadata fname, positives, negatives = [l.strip() for l in line.split('|')] ValueError: not enough values to unpack (expected 3, got 1)

May I ask how to add parameters to make the program run normally? Thanks a lot.
