How to run the example script provided in paper?

[kexul]

Hi guys, I cloned the repo and tried to run the following code provided in the paper, but it complained:

  File "/root/group_ceph/espaloma/example.py", line 3, in <module>
    dataset = esp.data.dataset.GraphDataset.load('gen2').view(batch_size=128)
  File "/root/group_ceph/espaloma/espaloma/data/dataset.py", line 316, in load
    paths = os.listdir(path)
FileNotFoundError: [Errno 2] No such file or directory: 'gen2'

Do you have any suggestions for what I should do next?

I found that there are some h5 files in data folder, another error raised when I tried to load it by pandas:

  File "H5F.c", line 620, in H5Fopen
