NLTK 包不在生产中工作，但在开发中工作

Question

我使用 Django 创建了一个网络应用程序。我想在这个网络应用程序中添加从内容中提取短语的功能。我的代码在开发中运行良好，但在生产中却无法运行。使用

nltk

包我创建了一个函数，它返回内容中的短语列表。下面是我的代码：

import nltk
from typing import List


def extract_phrases(content: str) -> List:
    # Tokenize text into sentences
    sentences = nltk.sent_tokenize(content)
    # Initialize list to store phrases
    phrases = set()

    # Iterate through each sentence
    for sentence in sentences:
        # Tokenize sentence into words
        words = nltk.word_tokenize(sentence)

        # Get part-of-speech tags for words
        pos_tags = nltk.pos_tag(words)

        # Initialize list to store phrases in current sentence
        current_phrase = []

        # Iterate through each word and its part-of-speech tag
        for word, pos_tag in pos_tags:
            # If the word is a noun or an adjective, add it to the current phrase
            if pos_tag.startswith("NN") or pos_tag.startswith("JJ"):
                current_phrase.append(word)
            # If the word is not a noun or adjective and the current phrase is not empty,
            # add the current phrase to the list of phrases and reset it
            elif current_phrase:
                phrases.add(" ".join(current_phrase))
                current_phrase = []

        # Add the last phrase from the current sentence (if any)
        if current_phrase:
            phrases.add(" ".join(current_phrase))

    return list(phrases)

功能和整个网络应用程序在开发环境中正常运行。但在使用 nltk 模块的生产中，该行未执行。

注意

我已经激活了我的虚拟环境并运行了以下代码：

import nltk
nltk.download('all')

Answer 1

我们必须提供下载的 nltk 文件的路径。

import nltk

NLTK_PATH = 'path of files'
nltk.data.path.append(NLTK_PATH)
