我删除了CIFAR_INPUT_ITER类_init_函数中的np.save/np.load代码，代码执行会报下面的错误

所以想请教一下这段代码在这里起到的作用是？

DataLoaders_DALI/cifar10.py

Lines 121 to 122 in 28e2308

    
           np.save("cifar.npy", self.data) 
        
           self.data = np.load('cifar.npy')  # to serialize, increase locality

这里是为了让数据能连续存储，dali要求数据的存储是连续的来增加locality，提高访问速度
