Azure ML LibraryExecutionError

Question

I get the following error when trying to retrieve the data from Azure Machine Learning

Error: LibraryExecutionError
Target: Score Model (AFx Library)
Message: table: The data set being scored must contain all features used during training, missing feature(s): 'NA'.

If I include NA within the values that get sent to Azure I get the following message

Parsing of input vector failed. Verify the input vector has the correct number of columns and data types

Has anyone got any idea's on how to fix this issue?

Answer 1

It seems that the error is suggesting that the model you produced from the training experiment uses a column named "NA", and this column doesn't existing in your scoring dataset.

Answer 2

Not a lot of detail to go off, but have you had NA values in that factor before? It sounds like you have a categorical factor and are entering a value for which it has no match and your model does not have the "allow unknown categories" checkbox checked.
