KeyError: 'generator'

[Amanb0420]

The first command under the bilateral perturbation section:
python research/TranSpeech/hubertCTC/gen_IE.py --ckpt /path/to/ckpt --wav /path/to/TGT_AUDIO --out /path/to/S2/dataset
successfully loads the mhubert model. However it returns a KeyError where the key 'generator' is not found in the config or the model. Please help as soon as possible
