Replica PointNav dataset about synsin HOT 8 CLOSED

One thing I noticed is that you're trying to load a config from the original path (on Olivia's machine) which is set here. You need to make sure to update the paths to your own machine and where you download the dataset. I don't recall what I specifically did to circumvent the Replica issue beyond what I wrote above as it's been three years. Sorry I can't help more. Good luck!

Yeah you download Replica independently (it's linked under the Replica heading)

@oawiles, thank you for the very quick response.

Sorry if my first question was vague; I did download the replica dataset, but this line refers to a pointnav dataset for the 3 splits. Habitat-api provides pointnav datasets for Matterport3D but they don't provide one for Replica.

I can use habitat-api to generate a pointnav dataset for Replica, but it seems to involve some degree of random sampling, and I wanted to make sure I was using the same dataset as the paper for direct comparison.

I would appreciate any clarification if I am missing something. Thanks again for your help!

Oh I see! Sorry I was confused. Yes you should generate your own but actually you may not need to:
The pointnav stuff isn't really used beyond it being how we record the scenes that exist in the dataset. But then we saved this to one scene per environment here. And I have these in the github repo here. So you should be able to just use those saved zip files and the point nav datasets shouldn't matter.

(sorry this is confusing -- I don't think Habitat was really supposed to be used for view synthesis so I kind of hacked around their assumption it's for controlling a robot in an environment).

Thanks a lot for the clarification; that makes a lot of sense. I noticed it wasn't really being used in the code, but wasn't sure if habitat-sim was somehow using it under the hood. I think I still need to generate it because habitat-sim expects it, if I find a way around that, I will update this issue.

Update: After looking more into using the one_scene_per_environment datasets, I realized that you were making my life much easier. I could simply comment out L131-148 here, and have the data_dir point to the appropriate directory.

One issue that I ran into was that the datasets you generated had some hardcoded paths; this was easily fixable by updating the paths as done in L47 and L157.

Thanks again!

@mbanani @oawiles Hi,i have some same problems like this.
When I run the code to generate the Replica dataset, the program reports an error:

Loading dataset replica ...

    raise RuntimeError(f"No file found for config '{config_path}'")
RuntimeError: No file found for config '/private/home/ow045820/projects/habitat/habitat-api/configs/tasks/pointnav_rgbd.yaml'

I don't know how to actually not use pointnav stuff.But I seem to have to pass a pointnav file in.
Can you give me some advice? thank you very much

Thank you for your reply! I understand what you said that I need to update the paths.
But like what you wrote above, the replica dataset I use I don't know where to find its pointnav.
And like Olivia @oawiles said, it seems that pointnav is not actually used. Is there any way to avoid calling this file？

from synsin.

I realize that pointnav is just a base config file and has nothing to do with Replica. But when I choose the correct path, the program will report a new error.
