Some problem of training process

[ziyouzheilu]

I have set the following lines in main.py:
25: is_testing =False

training with BIPED

223: TRAIN_DATA = DATASET_NAMES[0]

I set the following settings in the dataset. py file:
'BIPED': {
'img_height': 720, #720 # 1088
'img_width': 1280, # 1280 5 1920
'test_list': 'test_pair.lst',
'train_list': 'train_rgb.lst', # Base augmentation
# 'train_list': 'train_pairB3.lst', # another augmentation
# 'train_list': 'train_pairB5.lst', # Last augmentation
'data_dir': '/share/home/datasets/BIPED/edges', # mean_rgb
'yita': 0.5,
'mean':BIPED_mean
#
},
When I run:python main.py,it appears the following problems:

If you could tell me what the problem is, I would greatly appreciate it.
