🚀 Inference Example

from transformers import BertForSequenceClassification, BertTokenizer

tokenizer = BertTokenizer.from_pretrained("sh7vashrestha/BertBaseUncased-SenetimentAnalysis")
model = BertForSequenceClassification.from_pretrained("sh7vashrestha/BertBaseUncased-SenetimentAnalysis")

inputs = tokenizer("The movie was absolutely wonderful!", return_tensors="pt")
outputs = model(**inputs)
prediction = outputs.logits.argmax(dim=1)
print(prediction)
label_mapping = {0: "negative", 1: "positive"}
prediction_label = label_mapping[prediction.item()]
print(prediction_label)
