报错大致是这样的，但是直接run没有问题，debug就停住不动了

后来才发现是自己 import 自己定义的datasets的时候出现了错误，因为我是在自己定义的datasets中进行了测试，但是里面有错误，然后我还在主程序中import了这个datasets，所以一直停住不动。把dataset报错的地方删除就行，只留方法部分：

def collate_fn_paired_skip_invalid(batch):
    if len(batch[0]) == 5:  # 单任务情况 (添加了task_id)
        valid_batch_items = [item for item in batch if item[0] is not None and item[2] is not None]
        if not valid_batch_items:
            return torch.empty(0), torch.empty(0, 0), torch.empty(0), torch.empty(0, 0), torch.empty(0, dtype=torch.long)
        return torch.utils.data.dataloader.default_collate(valid_batch_items)

    else:  # 多任务情况 (7个元素，添加了task_id)
        valid_batch_items = [item for item in batch if item[0] is not None and item[2] is not None and item[4] is not None]
        if not valid_batch_items:
            return torch.empty(0), torch.empty(0, 0), torch.empty(0), torch.empty(0, 0), torch.empty(0), torch.empty(0, 0), torch.empty(0, dtype=torch.long)
        return torch.utils.data.dataloader.default_collate(valid_batch_items)

删除下面的，以免有错误

# trained_models_per_task = {}
#
# # 假设您在这里定义了 all_task_names
# all_task_names = [['A_bioavailability_ma'], ['A_hia_hou'], ['A_bioavailability_ma', 'A_hia_hou']]
#
# for current_task_names in all_task_names:
#     task_key = '+'.join(current_task_names)  # 创建任务组合的键名
#     print(f"\n--- 开始为任务组合: {task_key} 准备数据和模型 (Paired Data) ---")
