Model in Action 🚀

from transformers import GPT2Tokenizer, GPT2ForSequenceClassification

tokenizer = GPT2Tokenizer.from_pretrained("michelecafagna26/gpt2-medium-finetuned-sst2-sentiment")
model = GPT2ForSequenceClassification.from_pretrained("michelecafagna26/gpt2-medium-finetuned-sst2-sentiment")

inputs = tokenizer("I love it", return_tensors="pt")

model(**inputs).logits.argmax(axis=1)

# 1: Positive, 0: Negative
# Output: tensor([1])
