批量读取数据next_batch()简单实现

def next_batch(train_data, train_target, batch_size):  
    index = [ i for i in range(0,len(train_target)) ]  
    np.random.shuffle(index);  
    batch_data = []; 
    batch_target = [];  
    for i in range(0,batch_size):  
        batch_data.append(train_data[index[i]]);  
        batch_target.append(train_target[index[i]])  
    return batch_data, batch_target
