Hi @ilyayudkovich , this is correct -- the huggingface loader downloads the raw samples (ie, the pure text and quality signals). The user needs to subsample / dedupe the dataset as they see fit.

Would it be a useful feature for you to have a flag in the samples returned from the datalaoder that indicate whether or not the document is a duplicate?

Hey @mauriceweber , I like that idea. Would the original sample indicate that it's a duplicate via that flag to mitigate the need of keeping track of hashes/doc_ids to ensure you've got a duplicate?

yes exactly -- and it would be a global deduplication flag so you get unique documents across all commoncrawl snapshots.

Ah that'd be perfect if you could implement that. What do you think the timeline looks like for that?

Hello, have you already implemented it @mauriceweber ?
Thanks

Hi @joaomiguel26 -- sorry for the late response, I am working on it now, should have it ready early next week at the latest.

Thanks @mauriceweber !

Thanks @mauriceweber !

@mauriceweber another question about de-duplication, do we know if documents are unique per snapshot, or there may duplicates per snapshot as well?

the deduplication is global across all snapshot -- so that means if you're only interested in only a single snapshot, there will be more documents discarded than strictly necessary (but you get unique ones).

awesome thanks for the clarification @mauriceweber , looking forward to utilizing the global dedupe

@ilyayudkovich I implemented the dedupe flag now in the deduplicate_flag branch as an additional field is_duplicated in the quality_signals dict. You can tes it using

from datasets import load_dataset

ds = load_dataset("togethercomputer/RedPajama-Data-V2", name="default", snapshots=["2022-49"], languages=["en"], streaming=True, revision="2cae54f422505166bf6529ab2d2835fe2e17231")

for sample in ds["train"]:
    print(sample)
    break

which should return:

{'raw_content': "Forum Start ...", 'doc_id': '2022-49/0000/en_head.json.gz/0',  ...'quality_signals': '{ ... , "is_duplicate": true}'}

this is incredible, thank you Maurice!

Thank you @mauriceweber !

Hey @mauriceweber ,

Im trying to run the sample code above and am getting an issue utilizing that revision.
The way that I've got it set up to pull the data:

datasets.set_caching_enabled(False)
ds = datasets.load_dataset("togethercomputer/RedPajama-Data-V2", name="default", snapshots=["2022-49"], languages=["en"], streaming=True, revision="2cae54f422505166bf6529ab2d2835fe2e1723b1")

The error that I'm getting is:

Using the latest cached version of the module from /Users/XXX/.cache/huggingface/modules/datasets_modules/datasets/togethercomputer--RedPajama-Data-V2/4db97fc3d3261d52f9b87fcab64d3a258ca823adc36138396a5b5c7da789550e (last modified on Mon Nov 13 17:45:31 2023) since it couldn't be found locally at togethercomputer/RedPajama-Data-V2., or remotely on the Hugging Face Hub.

Not sure if i need to do anything on my end, maybe update the datasets package or something else. Let me know!

oh this is a typo on my end in the revision tag -- I fixed it now, so the above code should run now!

texas sized 10-4, can see the new flag there!

Im not sure about the process, but will i always need to provide the revision when downloading the dataset, or does at some point it get merged into "main" branch of the dataset?

To confirm, the quality signal is_duplicate will also be there when downloading the dataset rather than streaming as well

I merged it into main now, so you can drop the revision parameter in the future.

Yes -- I made the streaming example just because it's convenient to get quick glimpse at what get's loaded

Hello @mauriceweber , why was this change reverted?

Hi @joaomiguel26 , there are some duplicates files which do not exist (because there are no duplicates in the respective shard; see #18 for context) and this leads to an error during download which is not handled by the download manager. I am working on a more stable implementation currently.

Note that you can still stream the dataset in the deduplicate_flag branch -- with streaming enabled, these errors get handled.

Do you have an idea of when the more stable implementation would be ready?

@joaomiguel26 sorry for the delay here -- I just updated the dataloader script with a more stable version. It essentially skips everything in a blacklist of files which don't exist so that the dl_manager doesn't throw an error.

Thanks @mauriceweber !
