Example does not run

❓ Questions and Help

I’ve run into two issues with running example/example.py

1. The dataset name in the stable branch is wrong (fixed in master, 7a276e3db3ae5add52332624302b6790169a8b01), perhaps this should be cherrypicked into stable?
2. There is some strange pointnav import bug I cannot track down present in both stable and master. Perhaps I’ve installed the api incorrectly?

@smorad thank you for flagging it. I updated stable tag to include the fix. It should fixed now. You can always check how to install habitat-sim on fresh Ubuntu in our continuous testing. That’s how we make sure habitat-sim and habitat-api installation and examples, tests and baselines are not broken with new commits.

Closing as the issue looks resolved.
