Question

我在this link中有一个名为region_descriptions.json的JSON文件。此文件无法在Windows的notepad ++中正确加载（因为它是一个很大的文件）。该文件已部分加载到Google chrome中。该文件是我的密集字幕任务的数据集，我需要编写一个python脚本将其中的每个“短语”翻译成印地文。

我在Power Shell中导航到json文件所在的目录，然后使用以下命令设置环境变量： >>$env:GOOGLE_APPLICATION_CREDENTIALS="C:\Users\Preeti\Downloads\Compressed\region_descriptions.json"

此后，我尝试在同一目录中打开jupyter笔记本并运行代码：

import ijson
from google.cloud import translate

translate_client = translate.Client()

parser = ijson.items(open("region_descriptions.json"), "item.regions.item")

maxTranslations = 100;
for region in parser:
    translation = translate_client.translate(region["phrase"], target_language="hi")

    print(region["phrase"])
    print(translation['translatedText'])

    maxTranslations-=1
    if maxTranslations==0:
        break

但是jupyter笔记本给我一个错误：

AttributeError                            Traceback (most recent call last)

有人可以帮我写一个python脚本来将json文件中的所有短语翻译成印地文还是可以帮助我克服错误？我强烈建议从给定的链接下载json文件，以更好地理解我指的是“短语”。

Answer 1

由于文件很大，因此应使用ijson。

以下代码对我有用：

import ijson
from google.cloud import translate

translate_client = translate.Client()

parser = ijson.items(open("region_descriptions.json"), "item.regions.item")

maxTranslations = 100;
for region in parser:
    translation = translate_client.translate(region["phrase"], target_language="hi")

    print(region["phrase"])
    print(translation['translatedText'])

    maxTranslations-=1
    if maxTranslations==0:
        break

您应该考虑以下几点，以防上述情况对您不起作用：

不要忘记使用setup GOOGLE_APPLICATION_CREDENTIALS环境变量。
一切正常后，从break循环中删除for。
如果您不了解ijson的工作原理，将会发现this tutorial很有帮助。
