data preprocess

[starrlee356]

Hi, thanks for your work and code! In the original FB15k-237 dataset, there are entity2id.txt, relation2id.txt, train.txt, valid.txt, test.txt. However, in your generate_llm_questions.py, line 41, it tries to open and read a missing file stats.txt in data_path folder. And in line 45~51, it mentions other missing files which are not in the original data folder. What's more, it seems unclear how you generate those files in processed_path folder. Are those files generated by some preprocess codes? If so, could you share them?
