Inquiry on data/scene_datasets/mp3d/ directory #34

Open PhilipAmadasun opened 10 months ago

PhilipAmadasun commented 10 months ago

I'm a bit confused on the installation and test instructions on the ReadMe, is data/scene_datasets/mp3d/ just where one places the dataset from MatterPort 3D if they get access to it? Is this directory neccessary for just doing the tests provided in the readMe?

ericchen321 commented 10 months ago

data/scene_datasets/mp3d/ is where you place scene definitions and data/datasets/pointnav/mp3d/v1/ is where you place episode definitions.

It would be necessary if you want to reproduce our experiments that use the MP3D dataset.

@ericchen321 Thanks I think I understand, I was able to successfully run one of your the examples with ROS+Physics-HabitatSim. I have another inquiry, well two in fact: [i] The MP3D data set is Terabytes of data correct? Is it possible to request the owners of the data set grant the specific scenes that I want for the purpose of object identification, navigation and object interaction. [ii] This ties in to the last inquiry, do you guys have tutorials on how to use habitat sim to train for:

ericchen321 commented 10 months ago

@PhilipAmadasun [i] We just need a subset of the complete MP3D dataset. If I remember correctly I used python download_mp.py -o mp3d/ --task_data habitat to download just the data needed for running Habitat-related stuff. [ii] Sorry we don't have tutorials on training agents in Habitat Sim. Also we didn't really test the framework on tasks other than pointgoal navigation. But maybe you can extend it a bit so it works with those tasks?

@ericchen321 How do I go about doing that?(referring to the second inquiry). Is their any one on your development team I cant talk to about how to get started?

ericchen321 commented 10 months ago

To the best of my knowledge we don't have anyone on the team actively developing it. I'm just doing some maintenance so the old stuff still works. But I've left the group for a while so I might be wrong.

@ericchen321 Just for clarification, you guys used habitat-baselines to train the turtlebot for the navigation task example?

PhilipAmadasun commented 9 months ago

@ericchen321 Were you able to find any of the old team actively working on this? Would love to collaborate with someone if possible.
