stanford NER pyner错误：ConnectionRefusedError：[WinError 10061]无法建立连接，因为目标计算机主动拒绝它

Question

我在python中编写代码，我想使用standford NER。 我去了他们的网站：https://nlp.stanford.edu/software/CRF-NER.shtml#Download 并下载了python版本。 我试图在他们的网站上运行他们的例子，这是：

>>> import ner
>>> tagger = ner.HttpNER(host='localhost', port=8080)
>>> tagger.get_entities("University of California is located in California, United States")

并打算打印：

{'LOCATION': ['California', 'United States'],
 'ORGANIZATION': ['University of California']}

到屏幕。 而是行：tagger.get_entities（＆＃34;加利福尼亚大学位于美国加利福尼亚州＆＃34;） 抛出此错误：

我无法找到解决问题的方法。 任何人都知道如何解决它？
