Question

我试图在Azure ML Studio中使用相同的数据格式将一个数据帧附加到另一个数据帧。该脚本非常简单，但输出的数据类型不被理解＆＃34;错误，我无法弄清楚原因。

import pandas as pd
import numpy as np
def azureml_main(dataframe1, dataframe2):

    print('Input pandas.DataFrame #1:\r\n\r\n{0}'.format(dataframe1))

    new_dataframe1 = dataframe1.append(dataframe2)

    return new_dataframe1,

输入数据格式如下：

Input example:
2017-10-24T08:59:59.3+00:00     abcde   auto    41  0917D884    F48  36
2017-10-24T09:00:10.57+00:00    abcde   auto    52  0917H349    F20  65
2017-10-24T09:00:15.49+00:00    abcde   auto    7   0917D833    F48x 30
2017-10-24T09:00:15.91+00:00    abcde   auto    55  0917H366    F20  34
2017-10-24T09:00:16.49+00:00    abcde   auto    60  0917D954    F48  1

错误讯息：

我查了一下，不知何故标题栏被混淆了。纠正这个问题！

谢谢！
