jieba 分词不显示日志

问题

每一次我用jieba进行分词的时候，都会有

Building prefix dict from the default dictionary ...
Loading model from cache /tmp/jieba.cache
Loading model cost 0.128 seconds.
Prefix dict has been built succesfully.

这样的提示。怎么去除这些提示呢？

import logging
jieba.setLogLevel(logging.INFO)

或

jieba.setLogLevel(20)
