【问题描述】：
我有一个 18k 行的越南语数据集，我正在尝试使用 googletrans 模块将其翻译成英语。
from googletrans import Translator
translator = Translator()
def trans_text(df, text_field):
df[text_field] = df[text_field].apply(translator.translate, src='vi', dest='en').apply(getattr, args=('text',))
return df
trans_text(df_train.sample(1), "question")
我最终得到以下 JSONDecode 错误：
JSONDecodeError Traceback (most recent call last)

我理解这是由于我的 IP 被禁止而引起的。我查找了规避此问题的方法，发现使用 VPN 值得一试。我已经安装了 HolaVPN。但是，作为所有这一切的新手，我不确定如何重现与 solution 中相同的步骤，而不是 hola。任何有关要遵循的明确程序的提示都会有很大帮助。谢谢。
