Guidelines to support new models

[Bornholm]

First of all, thank you for this amazing project !

For a prototype of mine, i would like to be able to use this model from huggingfaces with the cybertron server.

I understand i should add support for the camembert model and i naively started to modify pkg/downloader/downloadmodel.go and pkg/converter/converter.go to be able to download/try to convert this model.

But i'm stuck at this error now:

Are there some guidelines i could follow to add support to new models in cybertron ? I would be happy to work on somes PRs :smile:

Thanks in advance !

Hi,

I'm interested too. Is there a guidelines or the possibility to learn how the library works ?

@ior308 Unless you read the code and write it yourself I don't see this happening. Advances/improvements in this area are moving too fast to keep up. Development seems halted in favor of Fortran (which, in my opinion, seems like wasted contributions but I'm sure people who use Fortran are happy).

[ior308]

Yes, it in an ever-changing world, but before I need help to make up the time I missed :)

Ok, I'll take a look at the code...

Regards
