How to acquire the shortest path for Objectnav task

[HanqingWangAI]

❓ Questions and Help

I try to replace the config file in /examples/shortest_path_follower_example.py Line65 with configs/tasks/objectnav_mp3d.yaml, but it seems that the agent always gets stuck in some corners.

Here are some visualized results I uploaded to GoogleDrive. It might due to that the sliding is not allowed. How to get the shortest path for Objectnav task?

BTW, I find a keyword 'shortest_path' in the training set xxxxxxxx.json.gz. What's the difference between this shortest path and the shortest path in the example.

Thanks

@qweas120, please re-download ObjectNav dataset and update your habitat-sim/habitat-api to latest master or challenge-2020 tags and re-try.

[HanqingWangAI]

@mathfac Thanks for your reply. Actually I try the examples using the provided docker image. Do I need to rebuild habitat-sim/habitat-api inside the container? Or I only need to pull the latest docker image?

I download the latest master branch and use fairembodied/habitat-challenge:testing_2020_habitat_base_docker docker image to run the example. The problem still not solved.
