如何将NLTK语料库添加到Google云功能? [英] How to add NLTK corpora to a google cloud function?

问题描述

我正在尝试运行涉及使用NLTK的Google云功能.我加了 textblob == 0.15.3 nltk == 3.4.3 到require.txt.但是，每次我运行该脚本时，它都会崩溃，并且日志显示请使用NLTK下载程序来获取资源:".

I am trying to run Google cloud function which involves the use of NLTK. I had added textblob == 0.15.3 nltk == 3.4.3 to the requirement.txt. But every time I run the script it crashes and the log shows "Please use the NLTK Downloader to obtain the resource:".

我知道我们需要下载NLTK语料库才能在本地系统中运行脚本.但不确定如何在Google Cloud Functions中下载它.任何帮助将不胜感激.预先感谢.

I know we need to download NLTK corpora to run the script in a local system. But not sure of how to download it in Google Cloud Functions. Any help will be greatly appreciated. Thanks in advance.

推荐答案

这是我通过Travis管道获取nltk_data的方式:

This is how I get the nltk_data through my Travis Pipeline:

    # To install the core NLTK package
    pip install nltk   

    # Installs only the extra packages you need. You could also use 'all' instead. 
    python -m nltk.downloader punkt averaged_perceptron_tagger wordnet    

然后，您可以将文件夹复制到功能文件夹中，并将其压缩:

Then you can copy the folder into your function folder, and zip it up:

    mkdir -p function/nltk_data/
    cp -a ~/nltk_data/. function/nltk_data/
    cp -a path/to/your/code/. function/

确保设置NLTK_DATA环境变量.因为我的文件夹结构是

Be sure to set the NLTK_DATA environment variable. As my folder structure was

    - nltk_data/
    - main.py
    - requirements.txt

我只需要设置NLTK_DATA = nltk_data，然后python可以找到文件.

I just needed to set NLTK_DATA=nltk_data, and then python can find the files.
