TypeError: only size-1 arrays can be converted to Python scalars解决办法

def ori_point(points):
    if len(points) == 1:
        origin = points[0]
    else:
        xyzmean = np.mean(np.array(points), axis=0)
        distances = np.sqrt(np.sum(np.asarray(xyzmean - points) ** 2, axis=1))
        origin = points[int(np.where(distances == np.min(distances))[0])]
    return origin

选择所有点中距离xyzmean最近的点，由于有多个点与xzymean的距离相同，导致无法正确选择距离最近，导致np.where(distances == np.min(distances)的返回值是具有多个索引值得元祖，故报错

改正方法改为：int(np.where(distances == np.min(distances))[0][0])永远取元祖中的第一个数字
