Starter kit stuck "pending" state for a day

The one important change I made is to defer importing RainbowAgent and tensorflow . See this commit here https://gitlab.aicrowd.com/felixlaumon/obstacle-tower-challenge/commit/4979d7e65de6012e92405542a1ab73ac6ea16cb4 . The evaluation ran successfully after this change.

@felixlaumon: It would also be great if you can send in a pull request by adding a note about this to the gcp_training doc in the starter kit.

Cheers,
Mohanty
