"[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

I assume you are trying to impute missing values before k-NN?0

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 regardless0 -
ah good. Glad you got it to work!
