tokenizer = AutoTokenizer.from_pretrained('mrm8488/RuPERTa-base-finetuned-pos')
model = AutoModelForTokenClassification.from_pretrained('mrm8488/RuPERTa-base-finetuned-pos')

id2label = {
    "0": "O",
    "1": "ADJ",
    "2": "ADP",
    "3": "ADV",
    "4": "AUX",
    "5": "CCONJ",
    "6": "DET",
    "7": "INTJ",
    "8": "NOUN",
    "9": "NUM",
    "10": "PART",

    "13": "PUNCT",
    "14": "SCONJ",
    "15": "SYM",
    "16": "VERB"
}

text ="Mis amigos están pensando viajar a Londres este verano."
input_ids = torch.tensor(tokenizer.encode(text)).unsqueeze(0)

outputs = model(input_ids)
last_hidden_states = outputs[0]

for m in last_hidden_states:
  for index, n in enumerate(m):
    if(index > 0 and index <= len(text.split(" "))):
      print(text.split(" ")[index-1] + ": " + id2label[str(torch.argmax(n).item())])
