E               AssertionError: `KMeans.predict()` does not check for consistency between input number
E               of features with KMeans.fit(), via the `n_features_in_` attribute.
E               You might want to use `sklearn.utils.validation.validate_data` instead
E               of `check_array` in `KMeans.fit()` and KMeans.predict()`. This can be done
E               like the following:
