Verify that the label data corresponds to the target values or input samples as required by the model.Double-check the input data and ensure that you are providing the correct and compatible label types expected by the machine learning model.To handle the 'Unknown label type: 'unknown'' error, consider the following steps:: The model raises a ValueError because it expects valid data samples for clustering, not labels. In this example, we try to fit the KMeans clustering model using a list of 'unknown' label type instead of the actual data samples. #Output:ValueError: Unknown label type: 'unknown' # Attempt to fit the clustering model with an 'unknown' label type X, _ = make_blobs(n_samples=100, centers=3, random_state=42)
