New Knime user; currently developing RF model. Large XLSX file input to Column Filter, Row Filter, Missing Value, Normalizer before X-Partition. After learning and pred node, X-Agg always fails indicating an error around a duplicate value.
Initially was a RowID duplicate. I created a RowID node to replace the original with a new column; however, X-Agg still returns a duplicate error based on the new column as well. If I exclude the specific impacted row, it just switched to a new value and still errors out.
I also placed a Duplicate Row Filter just before the X-Agg; however, workflow still fails.
Unsure how to mitigate this issue. Any help is appreciated!
