[INTEGRATION] Artifact error

[fnikolai]

sandbox-example.ipynb returns

FileNotFoundError: [Errno 2] No such file or directory: './models/7d78b3e35db94de195ece4634cc7c389'

This is caused by the paths not being propagated from notebooks to workers.

One solution is to define the paths everywhere are environment variables. The other solution is rely on ray's own mechanism for propagation of those variables.

In all cases, the artifact store must be a shared storage.

I get this error after deleting all data files from the artifacts folder, then running examples .ipynb.
