Usage

# For Transformers models (emotion, stress)
from transformers import AutoModelForSequenceClassification, AutoTokenizer

model = AutoModelForSequenceClassification.from_pretrained("BlessedRemzy/nostalgic-persuasive-models/emotion_model")
tokenizer = AutoTokenizer.from_pretrained("BlessedRemzy/nostalgic-persuasive-models/emotion_model")

# For pickle/joblib models
import joblib
from huggingface_hub import hf_hub_download

model_path = hf_hub_download(repo_id="BlessedRemzy/nostalgic-persuasive-models", filename="movie_recommender/lightfm_model.pkl")
model = joblib.load(model_path)
