<e_14159> SnoopJeDi: I spent quite some time trying to debug our CI. Turned out that tensorflow built on my laptop assumed AVX2 CPU instructions which the CI server CPU did not support.
<SnoopJeDi> When I learned about Lorena Barba's group's attempts to replicate their own version-controlled results, I gave up on scientific software
<e_14159> I did not hear about that.
<e_14159> Do you have a link?
<SnoopJeDi> Yep, very handy read and ref to give to people who are like "lol best practices are simple tho" https://arxiv.org/abs/1605.04339
<e_14159> Best practices are simple, though.
<e_14159> :P
<SnoopJeDi> yea they just don't happen to work :P
<SnoopJeDi> (always)
<SnoopJeDi> that said yea it's still very useful for most of the low-hanging fruit
<e_14159> They don't always work, or they always don't work? :D
<SnoopJeDi> the former, of course :)
<SnoopJeDi> just wait, NERSC is totally going to make their own Docker and that will definitely fix ALL of the problems :D
<SnoopJeDi> (I do think containerization represents a happy prognosis for science...just not Docker)
<e_14159> Reminds me of an issue my master's thesis adviser told me about: He tried to replicate some randomly generated stuff (had the seed). Except the MKL version changed, and therefore the result wasn't reproducible...
<e_14159> Singularity?
<SnoopJeDi> yyyyup that's basically what happened to her group
<e_14159> SnoopJeDi: No spoilers! :-)
<SnoopJeDi> it's only one of the Acts :P
<e_14159> SnoopJeDi: Extremely interesting read, and it is quite eye-opening how difficult it is to really reproduce something.
<e_14159> I have the advantage that, most of the time, ML doesn't actually have those big discontinuities, meaning that I should still get approximately the same results.
<e_14159> OTOH, did you see the NIPS talk by Ali Rahimi?
<bofh> e_14159: gods, I swear half the reason my master's supervisor put up with me so much is b/c I was good at being clairvoyant with numerics issues in failed reproductions... and yep, changing MKL ver (or to be precise, switching from stock LAPACK/QUADPACK to MKL) was one of them. :/
<bofh> but yea, agreed 10000%, best practises are actually hard.
<e_14159> bofh: I'm a computer scientist, I don't want to deal with issues in my abstraction.
<SnoopJeDi> e_14159, nope not familiar but would love a link to stick on my to-watch
<bofh> I'm a physical chemist (or chemical physicist, depending on day & mood), you think *I* do? :P
<bofh> I often don't get the choice.
<e_14159> SnoopJeDi: https://www.youtube.com/watch?v=Qi1Yry33TQE One of the things he mentioned was that, in one experiment, accuracy decreased from >90% to ~30% because they changed the floating point rounding for a neural network.
<e_14159> bofh: Despair?
<SnoopJeDi> e_14159, huh, that seems remarkably sensitive. Like something that'd stick out by looking at gradients or "fuzzing" inputs to see if they're stable?
<SnoopJeDi> but then, I'm not a NN person
<e_14159> SnoopJeDi: Yup, it's quite sensitive. The point of the talk, essentially, was that we have no clue how neural network training behaves, and it is more like "Alchemy" than science.
<SnoopJeDi> whee
<UmbralRaptor> (AAAAAAAAAAA)
<UmbralRaptor> I think the term that they're looking for is "neutrons"? https://photos.app.goo.gl/gL6dEf7ABj6cWHoM2
<SnoopJeDi> UmbralRaptor, hm?
<UmbralRaptor> (I mean, cross sections of about a kilobarn aren't exactly hard to detect)
<UmbralRaptor> Apparently the referenced paper finds a way to get down to the zeptobarn range in the present epoch?
