Text Classification GoEmotions

This a ONNX quantized model and is fined-tuned version of MiniLMv2-L6-H384 on the on the go_emotions dataset using tasinho/text-classification-goemotions as teacher model. The original model can be found here

Optimum

Installation

Install from source:

python -m pip install optimum[onnxruntime]@git+https://github.com/huggingface/optimum.git

Run the Model

from optimum.onnxruntime import ORTModelForSequenceClassification
from transformers import AutoTokenizer, pipeline

model = ORTModelForSequenceClassification.from_pretrained('minuva/MiniLMv2-goemotions-v2-onnx', provider="CPUExecutionProvider")
tokenizer = AutoTokenizer.from_pretrained('minuva/MiniLMv2-goemotions-v2-onnx', use_fast=True, model_max_length=256, truncation=True, padding='max_length')

pipe = pipeline(task='text-classification', model=model, tokenizer=tokenizer, )
texts = ["that's wrong", "can you please answer me?"]
pipe(texts)
# [{'label': 'anger', 'score': 0.9727636575698853},
# {'label': 'love', 'score': 0.9874765276908875}]
