我目前正在学习机器学习课程：来自 fast.ai 网站的课程。 该课程是一个视频，但它链接到 kaggle 上的 jupyter 笔记本（https://www.kaggle.com/code/jhoward/is-it-a-bird-creating-a-model-from-your-自己的数据）。然而，当我尝试运行 11 号手机时：包含此代码的手机：
#NB: `search_images` depends on duckduckgo.com, which doesn't always return correct responses.
# If you get a JSON error, just try running it again (it may take a couple of tries).
urls = search_images('bird photos', max_images=1)
urls[0]
我收到此错误：

我尝试成功运行上面的所有单元格：我的 Kaggle 帐户已验证并且我已启用互联网。 我怀疑 duckduckgo.com 网站无法正常工作（因为抛出的错误位于 if 语句内，并且如果 Http 响应代码包含 500，则验证该语句）：有没有办法让我检查是否是这种情况仅适用于我或其他所有人，如果是这样：是否有人找到了绕过此问题并仍然完成课程第 1 课的方法？
