try to run this project , like this: /projects/projectS/sigver/sigver/featurelearning/train.py --model signet --logdir ./../../npz --dataset-path /projects/projectS/sigver/npz/mcyt_170_242.npz --users 0 100 --epochs 10

has some problem:

@Tonyu what is the shape of your dataset? Note that the models were trained with grayscale images (1 channel)

@luizgh I think I used RGB format database. Thank you very much.
