How to Use

You can easily use this model with the Hugging Face transformers library. Here's an example of how to load and use the model for inference:

from transformers import AutoTokenizer, AutoModelForTokenClassification
import torch

model_name = "rigonsallauka/portugese_medical_ner"

# Load the tokenizer and model
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForTokenClassification.from_pretrained(model_name)

# Sample text for inference
text = "O paciente reclamou de fortes dores de cabeça e náusea que persistiram por dois dias. Para aliviar os sintomas, foi prescrito paracetamol e recomendado descansar e beber bastante líquidos."

# Tokenize the input text
inputs = tokenizer(text, return_tensors="pt")
