如何使用Python从向量列表中找到最接近所有其他向量的向量？

import numpy as np

def find_closest_vector(vector_list):
    closest_vector = None
    min_distance_sum = float('inf')

    for vector in vector_list:
        distance_sum = 0
        for other_vector in vector_list:
            distance_sum += np.linalg.norm(vector - other_vector)
        
        if distance_sum < min_distance_sum:
            min_distance_sum = distance_sum
            closest_vector = vector
    
    return closest_vector

# 示例用法
vectors = [np.array([1, 2, 3]), np.array([4, 5, 6]), np.array([7, 8, 9])]
closest = find_closest_vector(vectors)
print("最接近的向量：", closest)
