可能重复：
使用 nltk.data.load 加载english.pickle 失败

这是我在想要进行 POS 标记时遇到的问题，即使我已经导入了所需的项目。所以不确定是什么问题无法打印输出。谁能帮我指出我的代码有什么问题？

>>> import nltk
>>> import nltk.corpus
>>> from nltk.corpus import brown
>>> from nltk.corpus import treebank
>>> import nltk.tag
>>> from nltk import tokenize
>>> from nltk import word_tokenize
>>> from nltk import pos_tag
>>> text=nltk.word_tokenize("Historians have scant knowledge about Borneo's earl
y history, a certain fact though is the presence of modern man in Sarawak some 4
0,000 years ago (discovery of a Homo Sapiens skull at the Niah Caves), but most
of today's indigenous populations belong to the same Austronesian groups, brough
t by maritime migratory waves in the last 5,000 or so years, who have settled al
ong the Malayan peninsula, the Indonesian, Philippine, Micronesian and Polynesia
n archipelagos, and as far as Madagascar to the west and Easter Island to the ea
st.")
 >>> nltk.pos_tag(text)

错误：

就像错误说的那样，您需要使用 NLTK 下载器来下载资源taggers/maxent_treebank_pos_tagger/english.pickle。

您可以通过import nltk; nltk.download()从 Python shell 运行来执行此操作。您需要的文件位于模型选项卡下，名为maxent_treebank_pos_tagger.
