from transformers import pipeline
pipe = pipeline("fill-mask", model="FacebookAI/roberta-base") # Load model directly
from transformers import AutoTokenizer, AutoModelForMaskedLM
tokenizer = AutoTokenizer.from_pretrained("FacebookAI/roberta-base")
model = AutoModelForMaskedLM.from_pretrained("FacebookAI/roberta-base", device_map="auto")
