在AzureML自定义python库中使用Azure存储库

Question

我对Python有点陌生，所以我可能不完全理解如何准确地将库导入azureml

我有一堆数据存储在表存储中，我有本地Python代码来成功地连接所有这些数据，为ML实验做准备。我了解到AzureML环境没有安装Azure存储库，因此根据this的步骤来上载包含在anaconda3\lib\site包下找到的Azure存储库的ZIP文件。我把所有的azure目录放在一个zip文件下，然后按照链接中文档的底部上传zip文件作为数据集，并将数据集附加到ML中的executepython脚本节点

当我尝试运行节点时，会出现如下错误：

我不确定我做错了什么

在azuremlstudio中，Python脚本（以及R脚本）在沙盒中运行，因此无法通过网络访问资源。见limitations：

The Execute Python Script currently has the following limitations:

1. Sandboxed execution. The Python runtime is currently sandboxed and, as a result, does not allow access to the network...

因此，如果要从blob读取数据，请使用单独的导入数据模块；如果要向blob写入数据，请使用单独的导出数据模块。你知道吗
