When I use my own dataset,it throws error as following,i am sure my dataset path is correct,but it still .Could you please help me?

E:\Anaconda3\envs\lpb\python.exe D:/ASIS-master/gen_h5.py
D:\ASIS-master\data\indoor3d_ins_seg_hdf5\Area_1_hallway_1.h5: (3, 4096, 9), (3, 4096), (3, 4096)
D:\ASIS-master\utils\data_prep_util.py:95: H5pyDeprecationWarning: The default file mode will change to 'r' (read-only) in h5py 3.0. To suppress this warning, pass the mode you need to h5py.File(), or set the global default h5.get_config().default_file_mode, or set the environment variable H5PY_DEFAULT_READONLY=1. Available modes are: 'r', 'r+', 'w', 'w-'/'x', 'a'. See the docs for details.
h5_fout = h5py.File(h5_filename)
