I am very interested in your work and thank you for the code.But in the process of running the code, I encountered a problem that could not be solved, I hope you can give me some help：

Traceback (most recent call last): File "/data/projects/zero-simple2/trainer.py", line 422, in main() File "/data/projects/zero-simple2/trainer.py", line 215, in main train(opt, data_loaders['train'], model, epoch) File "/data/projects/zero-simple2/trainer.py", line 290, in train for i, train_data in enumerate(train_loader): File "/data/anaconda3/envs/pytorch/lib/python2.7/site-packages/torch/utils/data/dataloader.py", line 281, in next return self._process_next_batch(batch) File "/data/anaconda3/envs/pytorch/lib/python2.7/site-packages/torch/utils/data/dataloader.py", line 301, in _process_next_batch raise batch.exc_type(batch.exc_msg) KeyError: 'Traceback (most recent call last):\n File "/data/anaconda3/envs/pytorch/lib/python2.7/site-packages/torch/utils/data/dataloader.py", line 55, in _worker_loop\n samples = collate_fn([dataset[i] for i in batch_indices])\n File "/data/projects/zero-simple2/util/data_provider.py", line 107, in getitem\n caption.append(self.vocab(''))\n File "/data/projects/zero-simple2/util/vocab.py", line 34, in call\n return self.word2idx[word]\nKeyError: ''\n'
