AFx库函数库异常：无法找到文件：.. \ .. \ Dataset2 \ Dataset2.dataset。 。 （错误1000）

Question

我有一个简单的Azure机器学习实验，有两个输入块（“手动输入数据”），它们将输入传递给绑定两个输入的“Execute R Script”块。

当两个输入值相同时，我得到一个AFx库异常FileNotFound。当两个输入值不同时，一切正常。

这里是R代码和实验大纲。

d1 <- maml.mapInputPort(1) # class: data.frame 
d2 <- maml.mapInputPort(2) # class: data.frame 

print(d1) 
print(class(d1)) 

print(d2) 
print(class(d2)) 

我得到当我在两个输入块设置的相同的输入数据，进行更详细的错误是以下内容：

[Critical]  Error: Error 1000: AFx Library library exception: File: ..\..\Dataset2\Dataset2.dataset cannot be found.

任何建议是非常赞赏，弗洛。

因为只有一个输入数据集，所以应该删除引用第二个数据集的R代码。
