Question

每次运行它时，我都会得到TypeError告诉我操作数不支持Floats和Methods。我能不能让我知道我做错了什么以及如何解决这个问题？

from numpy import random,array,dot

class neural():
    def __init__(self):
        self.weights=2*random.random(3).reshape((3,1))-1
    def __sigmoid(self,x):
        return 1/(1+exp(-x))
    def predict(self,inputs):
        print("called predict function successfully")
        #pass inputs through our neural network (our single neuron)
        return dot(input,self.weights)

if __name__=="__main__":
    nn=neural()
    print(nn.weights)
    print(nn.predict(array([3,1,1])))

包括Traceback在内的例外是：

     12     nn=neural()
     13     print(nn.weights)
---> 14     print(nn.predict(array([3,1,1])))



      8         print("called predict function successfully")
      9         #pass inputs through our neural network (our single neuron)
---> 10         return dot(input,self.weights)

TypeError: unsupported operand type(s) for *: 'method' and 'float'

Answer 1

应该是：

return dot(inputs, self.weights)

不

return dot(input, self.weights)

input是内置函数，而inputs是函数的参数。哪个应该解释异常。

TypeError：*：＆＃39;方法＆＃39;不支持的操作数类型并且＆＃39;漂浮＆＃39;
