I am getting below error when I tried to run the impute node. I am having training dataset and want to fill the missing value for two variables with mean and count. Then ,connected the impute node to data partition

Please advise

You can't impute if a variable has more than 512 levels.

Thanks @PaigeMiller I got it now. I did impute after the data partition. It works now. Thanks

Hi,

I am getting the same error. I tried connecting the impute node to the data partition but getting the same error. @PaigeMiller How do I set the levels?

Hi ZaneleD,

The "levels" are the amount of labels you have for a variable. What you can do in order do decrease it is (in order of my recommendation):
- Replacement (map some of the categories into others)
- Group rare levels (group several similar labels together)

If you by any of those methods get the number of levels below the threshold of 512 it should work.
