If you want to impute numerical variables with this transformer, there are 2 ways of doing it: Option 1: Cast your numerical variables as object in the input dataframe, before passing it to the transformer. Option 2: Set ignore_format=True. Note that if you do this and do not pass the list of variables to impute, the imputer will automatically ...

The SimpleImputer class provides basic strategies for imputing missing values. Missing values can be imputed with a provided constant value, or using the statistics (mean, median or most frequent) of each column in which the missing values are located. This class also allows for different missing values encodings.
