我在 Jupyter Notebook 中编写 python，但是当我运行这段代码时：
import requests
import re
import spotlight
document = 'First documented in the 13th century, Berlin was the capital of the Kingdom of Prussia
(1701–1918), the German Empire (1871–1918), the Weimar Republic (1919–33) and the Third Reich (1933–
45). Berlin in the 1920s was the third largest municipality in the world. After World War II, the
city became divided into East Berlin -- the capital of East Germany -- and West Berlin, a West German
exclave surrounded by the Berlin Wall from 1961–89. Following German reunification in 1990, the city
regained its status as the capital of Germany, hosting 147 foreign embassies.'
annotations = spotlight.annotate('http://spotlight.dbpedia.org/rest', document,confidence=0.5,
support=20)
它显示此错误，我该如何运行它？
ConnectionError: HTTPSConnectionPool(host='www.dbpedia-spotlight.orgrest', port=443): Max retries

谢谢你。
