Python urllib.request 在 Azure 笔记本中抛出 403

Question

尝试获取 Azure Notebooks 中的 TensorFlow Object 检测 API 模型，但我尝试的所有操作都显示 403 Forbidden。在本地或 AWS 上检索文件没有问题。

import six.moves.urllib as urllib
url = 'http://download.tensorflow.org/models/object_detection/rfcn_resnet101_coco_11_06_2017.tar.gz'
opener = urllib.request.URLopener()
opener.retrieve(url)

我尝试将 User-Agent 数据添加到 header 等，但失败了。尝试使用 wget 并且也给出了 403。我认为笔记本运行在 docker 容器中，所以可能存在一些问题。任何见解或 work-arounds 将不胜感激。

Azure Notebooks 有意限制对外部 URL 的访问。这最有可能防止人们使用 Notebooks 服务对其他站点执行拒绝服务攻击。

Access to external internet sites is restricted. However, we have white listed a number of important URLs:

All CRAN mirrors are on the white list, so you should be able to install packages using your favorite CRAN mirror.

Github is also white listed, meaning you can use devtools::install_github() to install packages that are not on CRAN, or get the development version of a package.
