使用KNN插图

Question

我正在用knn对我的数据集进行分类，代码如下：

from sklearn.model_selection import train_test_split

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)

但是我想用Python语言中的plotly绘制这个knn分类器。我该怎么做呢？

Answer 1

只需对您的数据遵循此https://plotly.com/python/knn-classification/示例。
