与KNN密谋

Question

我使用以下代码在数据集中执行KNN：

X_train, X_test, y_train, y_test = train_test_split(accidentes[['col1', 'col2', 'col3']],accidentes['col4'], train_size=0.7, shuffle=False)
knn = KNeighborsClassifier(n_neighbors=3, algorithm='auto', metric='manhattan')
knn.fit(X_train, y_train)
X_test['predictions'] = knn.predict(X_test)

但是我想在python中用plotly绘制这个knn clussifier
