Why do I get the results are different from you, and I can not understand？

[zhouhao-learning]

I want to get all the acc, but the result is this, can you tell me which troops?

This is my code

import keras
from mock.mock import self
from sklearn.metrics import roc_auc_score



class Histories(keras.callbacks.Callback):
    def on_train_begin(self, logs={}):
        self.acc = []
        return

    def on_train_end(self, logs={}):
        return

    def on_epoch_begin(self, epoch, logs={}):
        return

    def on_epoch_end(self, epoch, logs={}):

        return

    def on_batch_begin(self, batch, logs={}):
        return

    def on_batch_end(self, batch, logs={}):
        self.acc.append(logs.get('acc'))
        return

Mine was on keras 1.x, probably that's the reason?
