超时：从 Azure ML 实验中访问 Azure Blob 存储

Question

我想从 Azure ML 实验中访问 Azure Blob 存储。我完全遵循了答案 Access Azure blog storage from within an Azure ML experiment 但是，出现了一些错误。

我的代码是

from azure.storage.blob import BlobService

def azureml_main(dataframe1 = None, dataframe2 = None):
   dataframe1.to_csv("output.csv", index=True)
   account_name = "acount_name"
   account_key="rJfqPEFcbgpS...SKZrBs5J2eOq0IJYrc2Vg=="
   CONTAINER_NAME = "CONTAINER_NAME"

   blob_service = BlobService(account_name, account_key, protocol='http')
   blob_service.put_block_blob_from_path(CONTAINER_NAME,"output","output.csv")

错误日志爆了

感谢任何帮助或想法！

我尝试通过复制您的代码并上传包含 azure python library 的数据集 zip 文件来重现您的问题，但失败了。

根据报错信息，似乎只是网络层的问题。也许稍后再试一次，它会起作用的。

根据我的经验，其他建议如下。

1. 检查您的存储帐户是否启用了Configuration 选项卡中的Secure transfer required 选项。如果是这样，请删除protocol='http' 代码或更改为https。
2. 根据您使用的存储API，它是Azure Storage Python SDK 的旧版本0.20.3。您可以上传包含新版本 0.34.3 的数据集 zip 文件，而不是旧版本以重试。

希望对你有帮助。
