多标签版本KNN，TypeError: __init__() takes 1 positional argument but 2 were given

Question

在使用MLKNN时，传递x_train和y_train时报错TypeError: init() takes 1 positional argument but 2 were given

我的代码

classifier = MLkNN()
classifier.fit(features,labels)
pred = classifier.predict(x_test)
print(accuracy_score(y_test,pred))

报错信息
Traceback (most recent call last):

这个是参数对不上问题，你看看你classifier.fit(features,labels)的fit源码有多小个参数，导致参数不同，应该是新旧版本的变更问题
