ML with FFI

Suppose you wish to do some machine learning stuff with Deno, would it be optimal to use FFI with C over Rust?

That may be a strange thing to ask but I was just curious as someone who knows less C than Rust.

Haven't tried FFI with C so wanted to know if it was worth it.

yep, definitely

dj•10/13/22, 5:36 PM

there's https://github.com/denosaurs/netsaur which has a C backend

although much WIP atm but for simple models its performance is on par with tensorflow and even better

NeTTOP•10/13/22, 5:44 PM

Guess I gotta learn some C then

dj•10/13/22, 5:45 PM

don't really need to, Rust can be used as well

NeTTOP•10/13/22, 5:45 PM

I specifically had that doubt because Netsaur seemed cool and my rust FFI was like 1.7x slower than JS code itself

NeTTOP•10/13/22, 5:45 PM

Tho it's mostly just me and my bad code

dj•10/13/22, 5:46 PM

yea language shouldn't matter here, there must be something with the code

NeTTOP•10/13/22, 5:46 PM

Certainly

NeTTOP•10/13/22, 5:47 PM

I guess I'll go try to improve my rust code then

NeTTOP•10/13/22, 5:47 PM

Thanks btw

np, and btw make sure your ffi calls go through fast api otherwise they'll be just slow
