generator_collection.py batch_size issue

[ZyHUpenn]

Hi, thank you very much for sharing the DeepVID code. When trying DeepVID for training, I meet the error reporting which is:

of Images: 0

num_workers: 20
Building generators
0it [00:00, ?it/s]
Traceback (most recent call last):
File "/home/hziyi/DeepVID-master/DeepVID-master/./scripts/dipn2v_multi_train.py", line 180, in
global_train_generator = CollectorGenerator(list_train_generator)
File "/home/hziyi/DeepVID-master/DeepVID-master/source/generator_collection.py", line 448, in init
self.batch_size = self.generator_list[0].batch_size
IndexError: list index out of range

In your code, I found seems it will create json file by itself so I don't know where can I modify the content in json file. Also, I checked the created training.json, there seems already contain the batch_size term:
{"type": "trainer", "name": "core_trainer", "run_uid": "20211109-095033", "batch_size": 4, "steps_per_epoch": 360, "period_save": 100, "save_image_period": 50, "apply_learning_decay": 0, "nb_times_through_data": 3, "learning_rate": 5e-06, "loss": "mse_with_mask", "nb_workers": 28, "model_string": "20211109-095033_DIPN2VGenerator_replace_0.1_mse_with_mask_pre_post_frame_3_multi", "output_dir": "/projectnb2/rise2019/cl6/Voltage_Imaging/scripts/../results/20211109-095033_DIPN2VGenerator_replace_0.1_mse_with_mask_pre_post_frame_3_multi"}

Can you help with the issue? I only used your training command $ python ./scripts/dipn2v_multi_train.py.
