hi,i run the multi_label_classifier.py and met the following error: usage: multi_label_classifier.py [-h] --dir DIR --name NAME --mode MODE --model MODEL [--load_size LOAD_SIZE] [--input_size INPUT_SIZE] [--ratio RATIO] [--batch_size BATCH_SIZE] [--shuffle] [--flip] [--region] [--load_thread LOAD_THREAD] [--crop CROP] [--gray] [--gpu_ids GPU_IDS] [--box_ratio BOX_RATIO] [--box_scale BOX_SCALE] [--input_channel INPUT_CHANNEL] [--mean MEAN] [--std STD] [--padding] [--checkpoint_name CHECKPOINT_NAME] [--pretrain] [--validate_ratio VALIDATE_RATIO] [--sum_epoch SUM_EPOCH] [--save_epoch_freq SAVE_EPOCH_FREQ] [--save_batch_iter_freq SAVE_BATCH_ITER_FREQ] [--lr LR] [--gamma GAMMA] [--lr_mult_w LR_MULT_W] [--lr_mult_b LR_MULT_B] [--lr_policy LR_POLICY] [--lr_decay_in_epoch LR_DECAY_IN_EPOCH] [--momentum MOMENTUM] [--weight_decay WEIGHT_DECAY] [--loss_weight LOSS_WEIGHT] [--top_k TOP_K] [--score_thres SCORE_THRES] [--label_file LABEL_FILE] [--classify_dir CLASSIFY_DIR] [--display_winsize DISPLAY_WINSIZE] [--display_id DISPLAY_ID] [--display_port DISPLAY_PORT] [--image_ncols IMAGE_NCOLS] [--html] [--update_html_freq UPDATE_HTML_FREQ] [--display_train_freq DISPLAY_TRAIN_FREQ] [--display_validate_freq DISPLAY_VALIDATE_FREQ] [--display_data_freq DISPLAY_DATA_FREQ] [--display_image_ratio DISPLAY_IMAGE_RATIO] multi_label_classifier.py: error: argument --dir is required Process finished with exit code 2

i debuged,i found the code in multi_label_classifier.py opt = op.parse()

i debuged step by step ,i found this line can't return a value''opt'" ,very strange.

Some of options are required and some are optional. You will need to specify those required options.

I have set those required options,e.g. dir,name,but the error still occur.When i change those relevant code "required=True" to "type=str" ,it works.
