執行Azure ML Studio中失敗的Python腳本模塊

Question

我在Azure ML Studio中使用“執行Python腳本”模塊，並編寫了最基本的代碼：

import pandas as pd
def azureml_main(dataframe1 = None, dataframe2 = None):
    dataframe1["Result"] = dataframe1["3MPurchNo"] * 3
    return dataframe1,

失敗並顯示以下錯誤：

File "C:\server\XDRReader\xdrwriter3.py", 
line 190, in write_object
raise NotImplementedError
('Python Bridge conversion table 
not implemented for type [{0}]'.format(value.getType()))
NotImplementedError: 
Python Bridge conversion table not implemented for 
type [<class 'numpy.int32'>]
Process returned with non-zero exit code 1

Answer 1

這似乎是一個錯誤/功能，帶有int列的數據框將無法成功返回到ML Studio。 您可以通過將列轉換為浮點型來修復它。

import pandas as pd
def azureml_main(dataframe1 = None, dataframe2 = None):
    dataframe1["Result"] = (dataframe1["3MPurchNo"] * 3).astype(float)
    return dataframe1,

希望這對別人有幫助
