使用keras包实现NLP问题时，报错
/lib/python3./dist-packages/keras/preprocessing/text.py”,
line , in texts_to_sequences_generator elif self.oov_token is not None:
AttributeError: ‘Tokenizer’ object has no attribute ‘oov_token’
报错的代码行为
train_sequences = tokenizer.texts_to_sequences(new_training_list)
从texts_to_sequences()点进去keras的源码，发现它调用texts_to_sequences_generator()方法
而该方法里没有oov_token,后面有调用，但是没有设置
手动设置就ok
在texts_to_sequences_generator()方法里添加
tokenizer.ovv_token=None
OK.Fine
