Question

我正在尝试使用python脚本将数据从MongoDB导入Azure机器学习。我使用以下脚本：

import pymongo as pymongo
import pandas as pd

def azureml_main(dataframe1 = None, dataframe2 = None):
    client = pymongo.MongoClient("SERVER:USERNAME:PASSWORD")
    db = client['DATABASE']
    coll = db['COLLECTION']
    cursor = coll.find().limit(10)
    df = pd.DataFrame(list(cursor))
    return df,

这给了我以下错误：

Error 0085: The following error occurred during script evaluation, please view the output log for more information:

这是不是由于将IP地址列入白名单而引起的？我找不到有关Azure ML产生哪种IP的任何信息。有没有解决此问题的方法？

Answer 1

该错误与IP白名单无关；这与无法连接到您的mongo数据库有关。检查您的连接字符串，并且您的服务器正在运行。连接字符串应类似于

mongodb://username:password@server:27017/yourdatabase?authSource=admin

首先使用您选择的命令提示符/ shell检查它是否有效

mongo mongodb://username:password@server:27017/yourdatabase?authSource=admin

然后将您的python连接更改为：

client = pymongo.MongoClient("<working connection string>")

将数据从MongoDB地图集导入到Azure Machinelearning
