import numpy as np import pickle import math f = open(r'C:\Users\sdnugeo\Desktop\target2.pkl','rb') bi = pickle.load(f) # bi = np.array(bi) data = np.arange(0, 156) print(data) data = data.tolist() # print(data) # 每次抽取1000个数值，共抽取10次 samples = [] c = [] a = 11 r = math.ceil(len(data)/a) print(r) for i in range(a): if len(data) > r : sample = np.random.choice(data, r, replace=False) else: sample = np.random.choice(data, len(data), replace=False) # for s in sample: # data.remove(s) # continue # print(type(sample)) # sample2 = np.array(sample) b = [bi[j] for j in list(sample)] # d = np.array(b) print(type(b)) c.append(b) # c = np.concatenate(c, axis=0) # c = bi[0] print(sample) # print(b) samples.append(sample) for s in sample: data.remove(s) # sample = [s for s in sample if s in data] samples = [np.array(s) for s in samples] samples = np.concatenate(samples, axis=0) c = [np.array(e) for e in c] c = np.concatenate(c, axis=0) # samples = np.array(samples).reshape(-1) print(samples) print(c.shape) 请帮我把这段代码修改成可调用的函数，要求可以调用每一个b

好的，可以将这段代码封装成一个函数，并返回每次抽样的b值，代码如下：

import numpy as np
import pickle
import math

def sample_data(filepath):
    f = open(filepath, 'rb')
    bi = pickle.load(f)
    data = np.arange(0, 156)
    data = data.tolist()
    samples = []
    bs = []
    a = 11
    r = math.ceil(len(data)/a)
    for i in range(a):
        if len(data) > r:
            sample = np.random.choice(data, r, replace=False)
        else:
            sample = np.random.choice(data, len(data), replace=False)
        b = [bi[j] for j in list(sample)]
        bs.append(b)
        samples.append(sample)
        for s in sample:
            data.remove(s)
    samples = [np.array(s) for s in samples]
    samples = np.concatenate(samples, axis=0)
    bs = [np.array(e) for e in bs]
    bs = np.concatenate(bs, axis=0)
    return samples, bs

你可以将这个函数保存在一个.py文件中，然后在其他的python文件中，通过import导入并调用该函数。调用方法如下：

from your_module import sample_data

filepath = r'C:\Users\sdnugeo\Desktop\target2.pkl'
samples, bs = sample_data(filepath)

# 获取第i次抽样的b值
i = 0 # 假设想要获取第1次抽样的b值
b_i = bs[i*r:(i+1)*r]

其中，filepath是你想要读取的pickle文件的路径。函数返回两个变量，分别为samples和bs，bs是每次抽样的b值所组成的数组。你可以通过bs[i*r:(i+1)*r]获取第i次抽样的b值。
