Eextension of the issus #479, chatbot.py cannot load the bloom model

Eextension of the issus #479, I only pass the step1_supervised_finetuning, use bloom-3b model.
And I run the following program:

python chat.py --path output/actor-models/bloom3b

I get the following error message：

Traceback (most recent call last):

return super().getattribute(key)
AttributeError: 'BloomConfig' object has no attribute 'layerdrop'

May I ask, does this mean that the programs provided by the github can only run OPT models?
If I want the program to use bloom model, how can I fix the above error?
