I’m trying to import ElectraForMultipleChoice from transformers, but I keep getting this error. I also attempted to install the most recent version of transformers with ‘pip install transformers --upgrade,’ but that did not work.

from transformers import AutoTokenizer, ElectraForMultipleChoice
import torch
​
tokenizer = AutoTokenizer.from_pretrained("google/electra-small-discriminator")
model = ElectraForMultipleChoice.from_pretrained("google/electra-small-discriminator")
---------------------------------------------------------------------------
