hello, can I ask you a question? I always meet the problem: it trouble me a lot

Loading completed! Traceback (most recent call last): File "d:/bysjchange_polygon_RNN-main/train.py", line 110, in train(config, config['pretrained']) File "d:/bysjchange_polygon_RNN-main/train.py", line 52, in train for step, data in enumerate(Dataloader):#4-> File "D:\Segment\envs\pytorch\lib\site-packages\torch\utils\data\dataloader.py", line 363, in next data = self._next_data() File "D:\Segment\envs\pytorch\lib\site-packages\torch\utils\data\dataloader.py", line 403, in _next_data
data = self._dataset_fetcher.fetch(index) # may raise StopIteration File "D:\Segment\envs\pytorch\lib\site-packages\torch\utils\data_utils\fetch.py", line 47, in fetch return self.collate_fn(data) File "D:\Segment\envs\pytorch\lib\site-packages\torch\utils\data_utils\collate.py", line 86, in default_collate raise TypeError(default_collate_err_msg_format.format(elem_type)) TypeError: default_collate: batch must contain tensors, numpy arrays, numbers, dicts or lists; found <class 'NoneType'>

How can I solve the None Type Error? Thank you and best wishes

dataset python generate_data.py --data train/val/test

Thank you! But it doesn't work. python generate_data.py --data train/val/test: count 0 max_count 0

can you show me how to set the path?

my structure:

pychache .vscode backbone datas img\test \ train \val label\test \train \val nets new_img\test new_label\test utils config_tools.py default_config.yaml fpstest.py generate_data.py test.py train.py validate.py
