请注意，你的代码缺少对xiu1在每个条件属性下的下近似集合的计算。在你的代码中，你只计算了xiu2和xiu3在每个条件属性下的下近似集合。以下是修改后的代码，包括计算xiu1在每个条件属性下的下近似集合：

import numpy as np
import pandas as pd

data = pd.read_csv("data/预处理.csv", header=None)
data = np.array(data)
cluster = []

# 按第二个到第十四个标签分类
for i in range(178):
    if len(cluster) == 0:
        cluster.append([0])
    else:
        m = 0
        for j in range(len(cluster)):
            n = 0
            for x in range(1, 14):
                if data[i][x] == data[j][x]:
                    n = n + 1
            if n == 2:
                cluster[j].append(i)
                m = 1
        if m == 0:
            cluster.append([i])

for i in range(len(cluster)):
    for j in range(len(cluster)):
        if cluster[i] == cluster[j] and i != j:
            cluster[j] = 0

# 定义函数来判断两个集合是否相似
def is_similar(set1, set2):
    for item in set1:
        if item not in set2:
            return False
    return True

xiu1 = []
for t in range(178):
    if data[t][0] == 1:
        xiu1.append(t)

xiu2 = []
for t in range(178):
    if data[t][0] == 2:
        xiu2.append(t)

xiu3 = []
for t in range(178):
    if data[t][0] == 3:
        xiu3.append(t)

# 输出xiu1, xiu2, xiu3在满足13个条件属性下的下近似集合
for col in range(1, 14):
    approx_xiu1 = [t for t in xiu1 if is_similar(data[t][1:14], data[x][1:14]) for x in xiu1]
    approx_xiu2 = [t for t in xiu2 if is_similar(data[t][1:14], data[x][1:14]) for x in xiu2]
    approx_xiu3 = [t for t in xiu3 if is_similar(data[t][1:14], data[x][1:14]) for x in xiu3]
    print(f"xiu1 在第{col}个条件属性下的下近似集合：", approx_xiu1)
    print(f"xiu2 在第{col}个条件属性下的下近似集合：", approx_xiu2)
    print(f"xiu3 在第{col}个条件属性下的下近似集合：", approx_xiu3)

现在，代码会输出xiu1、xiu2和xiu3在满足13个条件属性下的下近似集合。希望对你有所帮助！
