为什么我的代码调试没有完成？

Question

import numpy as np
import matplotlib as plt
import random

"""
def func(data):   #labels our train data
    train_labels = []
    i = 1
    for pt in data:
        if pt[0] > pt[1]:
            train_labels.append(1)
        else:
            train_labels.append(-1)

    return train_labels
        #print("{}. Punkt = {}".format(i, x))
        #i += 1

    if input >= 0:
        return 1

class Model:

    def __init__(self, nweights=1):
        self.nweights = nweights

    def setweights(self):
        self.weights = np.random.uniform(low=-1, high=1, size=(self.nweights, 1))
        return self.weights

    def guess(self, input):
        sum = 0;
        i = 0;
        while i < len(self.weights):
            sum += input[i] * self.weights[i]
        return func(sum)

train_data = np.random.randint(100, size=(1, 2))

brain = Model(1)
brain.setweights()
brain.guess(train_data)

你好， 我的代码有一点问题，因为它只是在加载，但我没有得到任何结果。所以它开始调试，但我没有得到任何错误或结果，它只是调试而没有完成。这个问题不能归结为任何硬件问题，所以它一定和我的代码有关。感谢您的帮助！

您的guess 函数陷入无限循环，因为您从未增加 i。

def guess(self, input):
    sum = 0
    i = 0
    for i in range(len(self.weights)):
        sum += input[i] * self.weights[i]
    return func(sum)
