Usage

python

import torch
from transformers import AutoTokenizer
from modeling_nps_score import NPSScoreModel

model = NPSScoreModel.from_pretrained(
    "nada-05/nps-score-camembert", trust_remote_code=True
)
tokenizer = AutoTokenizer.from_pretrained(
    "nada-05/nps-score-camembert", trust_remote_code=True
)
model.eval()

text = "J'ai attendu 40 minutes sans assistance. Vendeur peu aimable."
enc  = tokenizer(text, return_tensors="pt", max_length=256,
                 truncation=True, padding="max_length")
with torch.no_grad():
    out = model(**enc)
score_nps = round(out.logits.item() * 10, 1)  # → ex: 2.8
print(f"Score IA : {score_nps}/10")
