Usage

from transformers import AutoTokenizer, AutoModelForSequenceClassification
import torch

model_name = "jeongyoonhuh/koelectra-emotion-6class"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForSequenceClassification.from_pretrained(model_name)

text = "오늘 정말 기분이 좋아요!"
inputs = tokenizer(text, return_tensors="pt", truncation=True, max_length=256)

with torch.no_grad():
    outputs = model(**inputs)
    prediction = torch.argmax(outputs.logits, dim=1).item()

emotions = ['기쁨', '슬픔', '분노', '불안', '당황', '상처']
print(f"Predicted emotion: {emotions[prediction]}")
