python - 找不到资源 u'tokenizers/punkt/english.pickle'

Question

我的代码:

import nltk.data
tokenizer = nltk.data.load('nltk:tokenizers/punkt/english.pickle')

错误信息:

[ec2-user@ip-172-31-31-31 sentiment]$ python mapper_local_v1.0.py
Traceback (most recent call last):

    tokenizer = nltk.data.load('nltk:tokenizers/punkt/english.pickle')

    opened_resource = _open(resource_url)

    return find(path_, path + ['']).open()

    raise LookupError(resource_not_found)

LookupError:

use the NLTK Downloader to obtain the resource:

我正在尝试在 Unix 机器上运行这个程序:

根据错误消息，我从我的 unix 机器登录到 python shell，然后我使用了以下命令:

import nltk
nltk.download()

然后我使用 d-down loader 和 l-list 选项下载了所有可用的东西，但问题仍然存在。

我尽力在互联网上找到解决方案，但我得到的解决方案与我在上述步骤中提到的相同。

添加到 alvas' answer ，您只能下载 punkt 语料库:

nltk.download('punkt')

下载 all 对我来说听起来有点矫枉过正。除非那是你想要的。
