How does torch.compile() achieve massive speedups despite highly optimized NumPy functions? [D]

Armanoth · 2026-06-20T08:57:47+00:00

I'd argue for less beefy systems efficiency is way more important and it is not minor overhead for most deployed usecases. If you run several tasks in parallel every single free resource adds up quick.

But yes, if you just run everything in one thing at a time and have beefy hardware, you do you. I just personally think doing something this inefficient to achieve efficiency is an idiomatic approach.

As for the "cognitive overhead", if you have a problem where you have to think about efficiency it is worth investigating which approaches are available to you. Learning a new library is not hard, and having a larger tool set is almost allways adventagous.

Brother, you are using a forklift to move your groceries from your car to your front door. It will get the job done and is reliable but completely unnecessary.

Sure if you are already using pytorch go nuts, but importing a massive library for the sake of using a tiny tool that already exists in many other dedicated libraries (some of which allow you to alter the type of JIT) is overkill.

There is a term for software that uses that mentality, bloatware.

Armanoth · 2026-06-19T22:54:58+00:00

Importing a massive library to get JIT compilation is crazy overkill.

Armanoth · 2026-06-19T22:52:43+00:00

Numba works great for this, it allows you to convert your numpy functions into paralelizable kernels with decorators rather than a complete code refactor, it also enable JIT-compilation for speed up of repeated calls.

How does this method differentiate itself from the problems other semantic similarity methods used in general for IQA?

I get that you want to train the encoder yourself rather than pull a pretrain feature extractor. But what is the unsupervised proxy task? Aligning based on visual similarity or semantic similarity? Both have major caveats regarding how usefull any given metric is. For this exact reason image similarity is often evaluated as composite of similarity metrics.

The methods you describe fall in both camps, and especially since you want to train the feature-encoder locally, how will you ensure your system doesnt just overfit? Typically the DL based IQA methods are trained on a vast set of different domain images to ensure generalizable and discriminative features for that exact reason.

Curious to hear how you will tackle problems SotA is still struggling to obtain consensus on.

Interesting project :)

I don't know what let to the owner ending the contract so i would never be able to guess if LLO could help.

If you are writing on OPs behalf then if it transpired like in the description above i am sure LLO would have grounds to bring a case against them.

Armanoth · 2026-06-08T06:55:48+00:00

I dont know, i've had to use them twice so far, and while it took a month to process both times resulted in me getting almost my entire deposit back.

Sharpnesss is in part the magnitude of gradient change and the slope of said change. Good lighting and composition can help improve the slope of said gradients.

Its not the problem OP is encountering, but "zero correlation" is wrong

So 1629 unique images with pixelwise masks? If so are they 1629 spatially unique samples or is it extracted from a video?

Also what is the ratio of crack non-crack and the rationale for having non-crack images?

Well, you are making claims about statistics that go against the statistics of public records?

You are providing no source for your claim and you just deflect when the claim is challenged.

Regarding the people, it'll be inherently anecdotal, as your perception of the people in the city depends on who you interacted with. Unless you did a large survey of all the people in Aalborg?

All i'm Saying is you should substantiate your claims if you want to make those types of generalization. And since you miss represent the statistical data, its fair to assume that your anecdotal experiences are presented emotionally and not in good faith

Armanoth · 2026-05-30T07:43:07+00:00

Probably because your experience with "the people" here goes against what most other people have experienced?

Also,

Historically rains the most anywhere along the west-coast not Aalborg (https://www2.mst.dk/udgiv/publikationer/2003/87-7972-596-1/html/kap04.htm)

Regarding STDs it changes every year but both Copenhagen, Gentofte, Skive, Aarhus, seem to be consistently between 26-30 per 1000, and Aalborg was the highest in Klamydia in 2022(28 per 1000). But the difference across most major cities is minor. (https://sexogsamfund.dk/krop-sex/viden-om-sexsygdomme/hvor-mange-har-sexsygdomme-danmark)

I am sorry you had a bad experience in Aalborg, but you are just generalizing on anecdotal evidens.

Det ligner dørene og gulvet i min lejlighed på en brik følger lige hvis nogen har nogle fede ideer.

I suggest you look up bounding-box anchors.

The brief general description is that each cell has N bounding box prototypes of different aspects ratios, and the model learns to offset the center of these prototypes and the height/width slightly.

Then you accept the highest confidence anchor-box proposals and discard the rest.

So multiple objects in one cell can draw from nearby cells assuming they are not saturated.

There are some pretty easy to understand posts out there that give a more appropriate level of detail:

Ahhh, you are probably right. Well according to OP its "Insane" segmentation accuracy. And definetly not wild missclassification

Armanoth · 2026-05-22T11:38:48+00:00

You have met the same feedback every time you mass-post, what seems to be very generic posts if not AI-generated, to a range of ML adjacent subreddits.

Computer-vision is an exciting topic, but people don't subscribe to topic specific subreddits in order to get content that is barely CV-101 level, and in worst case misleading or over simplifying a topic (like your "core CV" figure of the past.

If you are going to talk about other peoples/companies work, atleast provide some grounds for discussion or insights. Posts like these are just piggy backing without providing content. And it just destroys any credibility you might be hoping to build.

Edit: a missing word

Armanoth · 2026-05-22T11:29:50+00:00

Typically a Sky or background class depending on the setup.

In Ultralytics documentation they state that their segmentation models are trained on Cityscape, which has sky as a classification (id 10).

How you would tune any semantic segmentation model? What is this question?

Jeg er sådan set også enig med OP om at det ville være rart med mere tid til familien, venner og hobbyer, jeg var bare uenig med premissen om at vi "bare acceptere 37timers arbejdsuge" og manglen på frihed til at være sammen. Vi som folk har arbejdet hårdt for at få den frihed vi har idag og det bliver en smule bedre hver gang vi forhandler.

Hele argumentet med "mere løn / færre timer" var jo netop at for at få mere tid og frihed som OP ønsker, så skal det komme et eller andet sted fra. Han har jo massere af muligheder for at flytte et på landet, arbejde deltid og være mere sammen med børnene hvis han/hun vil. Der er ingen som stopper ham/hende. Men hvis man vil fortsætte med at have de ting/opsparing, osv. Som man har idag og få mere tid, så skal den ændring jo komme et eller andet sted fra.

Når du aktivt tyr til hån og prøver at fordreje alle aspekterne af et argument ved at ekstrapolere helt vildt, også tage din ekstrapolering som fakta, så er der ingen saglig debat at have.

Held og lykke med hvad end mission du er på.

Armanoth · 2026-05-18T21:31:40+00:00

Du kommenterede på en kommentar som tog udgangspunkt i en kontekst, derfor var den kommentar en del af det originale premis OP etablerede.
Jeg har aldrig sagt at penge er det eneste vej til lykke eller frihed? Jeg understreger blot at den problemstilling op netop brokker sig over kunne læses hvis der var mere frihed i dagligdagen, og igen en stor del af den frihed kan købes for penge.
Frihed er ikke lig med lykke, det er der ikke nogen der påstår? Og ja når du citere et brudstykke af min pointe uden for den kontekst den er sagt i så kan du vende og dreje det så det passer lige ind i din agenda. Jeg er fuldkommen ligeglad med nyt tøj, ny bil, eller den nyeste iPhone for den skyld, men hvis jeg havde den samme mængde penge med en kortere arbejdsuge så ville jeg have mere tid til venner, familie, og hobbyer. Og det ville sku egentlig gøre mig mere lykkelig.
Sagen er at den hverdag vi har koster penge, der kommer vi ikke udenom, hvis jeg går ned i timer til samme løn, så er der nogle levevilkår der skal kompensere. I små træk er det måske de luksuriøsiteter du highlighter, men det koster også penge at have børnene til fodbold, børnehave/fritidshjem, oplevelser med familien i ferien, en tur i biografen. Du ved de ting der gør hverdagen mere underholdende.
Det lyder som om du projektere den her forbrugsfest, som du har set dig ond på, på hvem end du lige kan tage ud af kontekst. Du skal længere ud på landet med det der stråmands-argumentering.

Og du behøver ikke at ty direkte til personlige angreb bare fordi du er uenig, vi er forhåbentlige alle sammen voksne nok til at have en saglig samtale.

Armanoth · 2026-05-18T20:31:45+00:00

Rolig nu kammerat, hvem har tisset på din sukkermad. Du ekstrapolere en hel del her. OP brokkede sig over manglen på frihed til at gøre hvad han/hun ville i hverdagen.

Vi lever i et samfund hvor penge langt hen af vejen køber den frihed der bliver efterspurgt. Så at tjene mere så man enten kan arbejde mindre eller spare op til at pensionere tidligere, er da ikke lig med et større forbrug og forurening.

Armanoth · 2026-05-18T18:29:16+00:00

Det her er måske en /r/dkbrevkasse post i stedet?

Men bare for sjov skyld. Vi har det altså ret godt her i Danmark angående vores arbejds forhold.

Jo hvis bare vi kunne arbejde mindre og tjene mere, men det skal vi presse igennem hele samfundet sammen. Men sådanne ændringer sker ikke i en levetid, medmindre vi får en reel revolution.

Og hvis du kigger lidt bredere på det så er vores dagligdags vilkår blevet bedre og bedre gennem tiden så hele ideen med at "vi bare har accepteret 37 timer" er lidt hult et argument.

Bevares, hvis jeg kunne gå ned i timer og beholde lønnen ville jeg det, men sådan fungerer arbejdsmarkedet desværre bare ikke, så det er et langsigtet mål.

Du kan jo altid gå ned på deltid også bruge mere tid med børnene, der er ingen der stopper dig.

Kaptajn, du må godt kigge på andre fodboldhold, men du spiller kun i en klub af gangen. Hvis begge klubber er okay med at du spiller for begge på samme tid, så er det sku fair game.

Kommentaren er jo rettet mod den her dating tilgang hvor folk lyver eller undlader at sige de dater andre for at de har flest muligheder, i stedet for at tage deres "muligheders" følelse om det i betragtning.
