dataset_sem is missing

[apple2373]

I tried to run train_erp_sem.py but it has the following error

Traceback (most recent call last):
  File "train_erp_sem.py", line 18, in <module>
    from dataset_sem import Dataset
ModuleNotFoundError: No module named 'dataset_sem'

https://github.com/yuyanli0831/OmniFusion/blob/aaf52cc953ade3be1f5fc3df446705e4223b8d21/train_erp_sem.py

I guess dataset_sem is accidentally not in this repository.
