采用以下方法将数据集进行切分，怎样将data切分出的["data0", "data1", "data2", "data3", "data4", "data5", "data6", "data7"]列按照顺序进行合并，合并成一列。

# num_h=1，num_w=8

num_h, num_w = split_size 

slice_patches_op = vision.SlicePatches(num_h, num_w) 

transforms_list = [slice_patches_op] 

# data_cols = ["data0", "data1", "data2", "data3", "data4", "data5", "data6", "data7"]

data_cols = ['data' + str(x) for x in range(num_h * num_w)] 

data_set = data_set.map(operations=transforms_list, input_columns=["data"], output_columns=data_cols)
