на талосе я получаю эту ошибку несоответствия длины

Question

Я получаю следующую ошибку

Length mismatch: Expected axis has 29 elements, new values have 28 elements

мой код талоса:

import talos as ta
from talos.model import lr_normalizer, early_stopper, hidden_layers
t = ta.Scan(x=X.values, # data parameter is ignored in this example as here data varies based on batch_size & time_steps
            y=Y.values, # dummy data just to avoid errors. input and output calculated in create_model_talos
            model=my_lstm_model,
            params=params,
            experiment_no='1')
