Missmatch in annotation files #3

Closed mc-escobar11 closed 2 years ago

mc-escobar11 commented 2 years ago

Hi, I’m working on the hands-objects interactions benchmark and I have a question. I’m trying to use the dataloader for the state change localization and classification task but it asks for some fields in the json file that I don’t have in fhohands[set].json or in fhoscod[set].json. For example, the dataloader expects the fields ‘state_change’,’parent_pnr_frame’, ‘unique_id’ but I couldn’t find them anywhere in the annotation files. Also, the dataloader uses the fields ‘parent_start_sec’, ‘parent_end_sec’, ‘parent_start_frame’ and ‘parent_end_frame’. The closest fields I could find where in fhoscod[set].json 'clip_parent_start_sec', 'clip_parent_end_sec', 'clip_parent_start_frame', 'clip_parent_end_frame’. I was wondering if you could give me some insight on which is the correct annotation file I should be using. Thanks in advance!

Hello @mc-escobar11 ! Thank you for bringing the issue to our notice. I checked the files, and they are different. We are working on resolving this and will point you to the correct annotation files soon!

Thanks @mc-escobar11 , you want the files prefixed with fho_oscc-pnr_ (e.g. fho_oscc-pnr_train.json).

There was a period where those were not being downloaded via the CLI (as they were updated), but they should be available now. Can you please try pulling again with --datasets annotations and let us know if that matches with expectations?

Thanks for getting involved with Ego4D! Let us know how it goes.

I checked and they are available now, thanks for the quick reply!

Ah, fantastic. Sorry about the confusion then, that was an error on our side!

Do let us know how you get along with the dataset!
