如何修复 python 中的 hopfield 库错误

Question

我有一些关于 hopfield 网络的代码。我正在尝试使用 hebbian 训练来训练一些字母，然后添加噪音并对其进行降噪。但是，我对图书馆有疑问。我进行了搜索，但找不到问题的正确答案。 Hopfieldnet 库不工作，如果我尝试替换它，我会出现其他错误。你能帮帮我吗？

Answer 1

不确定这是否是问题的实际解决方案。我无法重现错误。代码经过 3 次轻微修改后适用于我。

(1) 进口

from random import randint
import numpy as np
from hopfieldnet.net import HopfieldNetwork  # modified import
from hopfieldnet.trainers import hebbian_training
from matplotlib import pyplot as plt

(2) 图

plt.subplot(3, 4, ...)  # 3 * 4 = 12 places for 10 plots

(3) hopfieldnet 模块 -> net.py -> class HopfieldNetwork -> 方法 run

update_list = list(range(self._num_inputs))  # list(range(...)) instead of just range(...)
