preprocess error

There are doubts in the preprocessing process, is the spatial language model in the code the four datasets of train, test, val, and split in the WMT16 multimodal translation task, and what code command line are these data sets imported through preprocess.py!以及我的preprocess.py的运行结果存在报错情况，如果能解答我的困惑，我将不胜感激！ As well as the running result of my preprocess.py, there are errors. If you can solve my confusion, I would be grateful!
