list index out of range when trying to predict

[guilhermenoronha]

Hello,

My code is getting the error of 'list index out of range' when I try to predict a sentence from the model. A analyzed your code but couldn't figure out what could it be.

Here is my code:

    model = WordsTagger(model_dir='name_model')
    tags, sequences = model([["meu", "amigo", "e", "senhor", "."]])
    print(tags)  
    print(sequences)

Here is the log:

`Traceback (most recent call last):

  File "C:\Users\guilh\OneDrive\Textos e Documentação\workspace\BI-LSTM-CRF Cartas\bilstmprocessor.py", line 30, in <module>

    begins = [b for idx, b in enumerate(begins) if idx == 0 or ts[idx] != "O" or ts[idx - 1] != "O"]

IndexError: list index out of range`

I'd appreciate any help. Thanks in advance. Best regards.

Hello, I can't fix the problem with the information you provide.
You can go inside the code in predict.py and print more info.
More specifically, print all inputs of the function "tokens_from_tags", the value of "begins" before the crash.

Please, check if the prints I've sent to you are enough. If not, let me know it. Best regards.

The bug is fixed in the new version 0.2.1. You can upgrade and try again.
Thanks for submitting the issue!
