I am getting this error

Hi @MuntahaShams I would need a little more information to provide you further help :).
The following points could root errors as this was just a quick tryout:

1. Have you changed the code / notebook in any way?
2. Have you added or deleted data samples?
3. It could be that the lib versions are not the same

However, I found a similar issue here: ray-project/ray#369
Maybe this helps you to debug the issue. Otherwise I would try to downgrade the lib versions to the time when the Repo was published :).
