Dear Professor:
I want these files to run experiments on the dmv data set:

data = pd.read_hdf("/home/ziniu.wzn/DMV/DMV_discretize.hdf")
query_l = np.load("/home/ziniu.wzn/DMV/cardinality/query_left.npy")
query_r = np.load("/home/ziniu.wzn/DMV/cardinality/query_right.npy")
true_card = np.load("/home/ziniu.wzn/DMV/cardinality/query_true.npy")

Thank you in advance for considering my request. I look forward to hearing from you soon, and I am excited to delve deeper into your valuable research.
