   I add a while loop in image.py:
   def next(self):
       ...
       try:
               while i < batch_size:
                   label, s = self.next_sample()
                   data = self.imdecode(s)
                   try:
                       self.check_valid_image(data)
                   except RuntimeError as e:
                       logging.debug('Invalid image, skipping:  %s', str(e))
                       continue
                   data = self.augmentation_transform(data)
                   assert i < batch_size, 'Batch size must be multiples of 
augmenter output length'
                   batch_data[i] = self.postprocess_data(data)
                   batch_label[i] = label
                   i += 1
           except StopIteration:
               if not i:
                   raise StopIteration
       while i < batch_size:
           import copy
           batch_data[i] = copy.deepcopy(batch_data[0])
           batch_label[i] = copy.deepcopy(batch_label[0])
           i += 1
       ...
   
   I copy the first batch_szie-i times, It can works.
