"[Solved] Missing values: The example set has no examples"
Hi
I have a simple process where I am trying to replace the missing values in a dataset using k-NN. When I connect my dataset to the "Impute Missing Values" Operator I get the error message "The example set has no examples"
The code is too large to paste here as there are about 300 variables.
Any help much appreciated

Altair EmployeeI assume you are trying to impute missing values before k-NN?
Hi Scott,
The Impute missing values operator is nested. Inside this operator is the K-NN operator. Retreiving the dataset (an excel file) and the Impute missing values are all that is in this workflow.

Hi - I have sorted this out. There were columns in the dataset which had no values at all which, upon refection, it was unreasonable of me to expect K-NN to fill in the values.
Thank you for your help regardless
