TypeError init() got an unexpected keyword argument ‘n_iter‘

TypeError: init() got an unexpected keyword argument ‘n_iter’

今天遇到一个报错：

Traceback (most recent call last):
  File "C:/Python/pythonProject/learning-nlp-master/chapter-9/classification/classifier.py", line 225, in <module>
    main()
  File "C:/Python/pythonProject/learning-nlp-master/chapter-9/classification/classifier.py", line 143, in main
    svm = SGDClassifier(loss='hinge', n_iter=100)
  File "C:\Users\Tony\anaconda3\lib\site-packages\sklearn\utils\validation.py", line 73, in inner_f
    return f(**kwargs)
TypeError: __init__() got an unexpected keyword argument 'n_iter'

Process finished with exit code 1

这是因为该分类器的参数n_iter 在新版本中变成了n_iter_no_change，所以只要把这一行的n_iter改为n_iter_no_change就行：

svm = SGDClassifier(loss='hinge', n_iter=100)

svm = SGDClassifier(loss='hinge', n_iter_no_change=100)
