jupyterhub - NLTK - 无法使用停用词 - 找不到资源停用词

Question

我正在使用下面的代码通过 jupyter notebook 使用停用词。 我在 Linux 服务器上托管了 jupyter 并使用了笔记本。

python3 -m nltk.downloader stopwords
python3 -m nltk.downloader words
python3 -m nltk.downloader punkt

python3
>>>from nltk.corpus import stopwords
>>>stop_words = set(stopwords.words("english"))
>>>print(stop_words)

这在 python 终端中运行时工作正常，但是当我在 Jupyternotebook 下面尝试时，它失败并出现错误。

from nltk.corpus import stopwords
stop_words = set(stopwords.words("english"))
print(stop_words)

    582     resource_not_found = "\n%s\n%s\n%s\n" % (sep, msg, sep)
--> 583     raise LookupError(resource_not_found)
    584 

LookupError:

  Please use the NLTK Downloader to obtain the resource:
