error in training

hi, I have trouble using src/sequencer-train.sh

### FULL ERROR OUTPUT
sequencer-train.sh start
Starting data preprocessing
Please backup existing pt files: /home/hxw170013/APR/chai/results/Golden/final.train*.pt, to avoid overwriting them!
Starting training

_pickle.UnpicklingError: invalid load key, 'v'.
sequencer-train.sh done

I think it might because of the outdated value in version of chai/results/Golden/final.train.0.pt. But I am not sure, Can you help me out on this? Thank you!

Start with src/sequencer-train.sh and the reported train.py entry points at lines 120 and 51. Then inspect OpenNMT-py/onmt/train_single.py line 114 and the chai/results/Golden/final.train*.pt files while reproducing sequencer-train.sh start. Done means the generated training data loads successfully and training completes without the reported UnpicklingError.
