Hi @nathanw-mlc can you please tell if there is a way to do checksum check while downloading files from MLCommons cloud? We do get errors like this due to incomplete downloads which are not getting flagged.

I'm also getting failed downloads for DLRMv2. Other downloads via MLCommons cloud have extremely erratic download rates.

[nathanw-mlc]

Has this been on ongoing problem? There was some server maintenance yesterday that caused unexpected interuptions.

[WarrenSchultz]

For the past week at least, I think?

[arjunsuresh]

@nathanw-mlc For us the concern is we are not able to validate the downloaded file as the checksum is not constant across repeated downloads. We first noticed this for gptj-6B download which was 2 months back - checksums were different but the downloaded zip file was extracted successfully and worked as expected.

[nathanw-mlc]

Hmm, that's very strange. Thanks for bringing this to my attention. I'm looking into it.
