@kushidhar0873 Hey,
The predict function in your class is written for a single datapoint p. While, when you are calling-

knn_model.predict(X_test)

you are passing the entire test dataset which has multiple samples. Try to call your predict function in this manner:

predictions = []
for pt in X_test:
    predictions.append(knn_model.predict(pt))

predictions[i] represents the predicted category of ith sample in X_test.
