如何无法定义问题类函数

Question

此代码给我这个错误：

self.model = create_model((name error：name

'create_model'未定义

from sklearn.neural_network import MLPRegressor
class model:
    def __init__(self, algorithm):
        self.algorithm = algorithm
        self.model = create_model()
    def create_model(self):
        if self.algorithm == 'MLPREG':
            return  MLPRegressor(hidden_layer_sizes=(20,), activation='relu', solver='adam', random_state=1, max_iter=3000, verbose=True)
def main():
    ex = model('MLPREG')
main()

我不明白，一切看起来正常。但是我无法运行该程序。

将您的类更改为：

class model:
    def __init__(self, algorithm):
        self.algorithm = algorithm
        self.model = self.create_model()
    def create_model(self):
        if self.algorithm == 'MLPREG':
            return  MLPRegressor(hidden_layer_sizes=(20,), activation='relu', solver='adam', random_state=1, max_iter=3000, verbose=True)
