## Basic Usage

```python
from transformers import pipeline, BertForTokenClassification, BertTokenizerFast

model_name = "rafola/BERT-base-pt-BR-person"
model = BertForTokenClassification.from_pretrained(model_name)
tokenizer = BertTokenizerFast.from_pretrained(model_name,use_fast=True)

nlp = pipeline("ner", model=model, tokenizer=tokenizer)

result=nlp("Como já dizia seu Zé Ricardo, A Luiza sempre vai atrás de uma encrenca, mesmo com todo o cuidado de tia Eliana com ela.")

print(result)
```
