ModuleNotFoundError: No module named '_regex'

Hi,

I have been using this transformer implementation for so long and everything worked well.
I have some trained model (saved in checkpoint) but now, after some time when I try to load the checkpoints for generation, I got this error which is rooted from dill package:

loading spacy tokenizers...
Traceback (most recent call last):
  File "translate_file.py", line 148, in <module>

    SRC = pickle.load(open(f'{opt.load_weights}/SRC.pkl', 'rb'))

    return __import__(import_name)
ModuleNotFoundError: No module named '_regex'

I have regex installed and dill version is 0.3.1.1
I guess my previous dill version maybe was sth else. But I cannot solve this error. I cannot load my trained model at all.
Do you have any idea?
Thanks.
