what if there is no groundtruth?

[zabir-nabil]

can it calculate the drift if there is no groundtruth data / y_target?

[YohannLeFaou]

Looking for instance at this example: https://github.com/zelros/cinnamon/blob/master/examples/breast_cancer_XGBoost_ModelDriftExplainer.ipynb

You can fit the drift explainer without passing any value for y1 and y2:

drift_explainer.fit(X1=X_train, X2=X_test)

You can then analyze drift between X1 and X2, but methods drift_explainer.get_target_drift(), drift_explainer.get_performance_metrics_drift() will not work.
