Solution
The error message indicates that there is an issue with the 'metric' parameter of the KNNImputer. The expected value for the 'metric' parameter is 'nan_euclidean' or a callable function, but the provided value is 'nan_enclidean'.
To resolve this issue, you need to correct the value of the 'metric' parameter to 'nan_euclidean' or provide a valid callable function. This can be done by modifying the code where the KNNImputer is used and ensuring that the correct value is passed for the 'metric' parameter.
