英文:
knn.fit(X_train, y_train) not showing parameters
问题
以下是翻译好的部分：
The output it shows, is below.
输出如下。
I expected the output to be:
我预期的输出应该是：
`KNeighborsClassifier(algorithm='auto', leaf_size=30, metric='minkowski',metric_params=None, n_jobs=1, n_neighbors=1, p=2,weights='uniform')`
As I am working through the book introduction to machine learning with Python by O'Reilly.
因为我正在阅读 O'Reilly 出版的《Python 机器学习入门》这本书。

只需在已拟合的对象上使用 get_params 方法。
from sklearn.neighbors import KNeighborsClassifierX = [[0], [1], [2], [3]]y = [0, 0, 1, 1]neigh = KNeighborsClassifier(algorithm='auto', leaf_size=30, metric='minkowski', metric_params=None, n_jobs=1, n_neighbors=1, p=2, weights='uniform')neigh.fit(X, y)neigh.get_params()
{'algorithm': 'auto','leaf_size': 30,'metric': 'minkowski','metric_params': None,'n_jobs': 1,'n_neighbors': 1,'p': 2,'weights': 'uniform'}
英文:
Just use the get_params method on the fitted object.
from sklearn.neighbors import KNeighborsClassifierX = [[0], [1], [2], [3]]y = [0, 0, 1, 1]neigh = KNeighborsClassifier(algorithm='auto', leaf_size=30, metric='minkowski', metric_params=None, n_jobs=1, n_neighbors=1, p=2, weights='uniform')neigh.fit(X, y)neigh.get_params()
{'algorithm': 'auto','leaf_size': 30,'metric': 'minkowski','metric_params': None,'n_jobs': 1,'n_neighbors': 1,'p': 2,'weights': 'uniform'}
