[BUG]: libritts_dataset.py of valle_v2

[CriDora]

When I write "dataset_list":["train-clean-360", "train-clean-100"] in valle_v2's exp_ar_libritts.json, and then execute
"python -m models.tts.valle_v2.libritts_dataset"
, the code self.trans_cache["Duration"] of train-clean-360 can be calculated correctly, but it will get stuck when calculating the self.trans_cache["Duration"] of the second dataset train-clean-100.
I put the two lines of code for setting ID in libritts_dataset.py
"self.metadata_cache.set_index("ID", inplace=True)
self.trans_cache.set_index("ID", inplace=True)"
after the calculation of duration and outside the for loop, and the above problem will not occur.
Is the above problem caused by my improper operation?
