使用Chaquopy在Android Studio中导入从nltk.corpus导入wordnet时出错

如何解决使用Chaquopy在Android Studio中导入从nltk.corpus导入wordnet时出错

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，它可以正常工作，但是在尝试导入wordnet时却给我错误。 注意：我已经在Gradle中安装了nltk，wordnet。

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

Logcat向我显示以下错误

解决方法

我在my previous answer中已经说过：

• wordnet pip软件包显然与NLTK无关，因此可以将其删除。
• 由于仿真器错误，您可能需要按here所述循环调用nltk.download。
