looking into it

[gideonite]

Seems to be a problem with the URL. The following also gives 403: Forbidden.

wget "https://storage.googleapis.com/copt/datasets/gisette.tar.gz"

[fabianp]

it's because I lost access to the google cloud instance that had the data. I'm trying to reconstruct it as it was before

From the peanut gallery: maybe best to put it on figshare, or somesuch, where persistent URLs can be minted and you don't have to worry about keeping google storage paid for.

[fabianp]

Thanks @arokem, that's a good idea. The issue is fixed but i'll leave it open to look into figshare

[fabianp]

@arokem do you know if one can upload to figshare and easily access it using urllib, i.e., without authentication?

[arokem]

Sorry : I missed the notification for your message until now. Yes, you can direct download from figshare with no authentication. The files have somewhat wonky URLs (e.g., https://ndownloader.figshare.com/files/5273800), but that's not an issue.

TODO for myself: upload again kdd10, kdd12, news20, criteo
