使用 Chaquopy 在 android studio 中导入（从 nltk.corpus 导入 wordnet）时出错

Question

import numpy as np
import nltk
nltk.download('wordnet')
from nltk.corpus import wordnet as wn

def main(a):

    b = wn.synsets(a)
    return b

我在使用 nltk.corpus 导入 wordnet 时出错。我使用了 numpy 库，它工作正常，但在尝试导入 wordnet 时出现错误。 注意：我已经在 Gradle 中安装了 nltk、wordnet。

python {
  pip {
    install "numpy"
    install "nltk"
    install "wordnet"
  }
}

Logcat 显示以下错误

      Please use the NLTK Downloader to obtain the resource:
    
      [31m>>> import nltk
      >>> nltk.download('wordnet')

Answer 1

正如我在my previous answer 中已经说过的：

• wordnet pip 包显然与 NLTK 无关，因此您可以将其删除。
• 由于模拟器错误，您可能需要在循环中调用nltk.download，如here 所述。
