Not able to read Kosarak dataset in a vector format.

[ronakagarwal1702]

When I'm reading .hdf5 file, getting train or test output as a number. For below example, output is 3954. For other dataset (Ex- fashionmnist, lastfm etc), I'm getting train, test data in a vector format for a given id. Could anyone help here to read the train, test data in vector dimension format for kosarak?

import h5py
import csv
file_path = "kosarak-jaccard.hdf5"
file_path_csv = "kosarak_train.csv"
with h5py.File(file_path, "r") as hdf_file:
    print(hdf_file['train'][100])
