[Feature Request] Support for GALACTICA & EleutherAI Neo & Neo X models
Support for the GALACTICA & EleutherAI Neo, Neo X models would be an awesome addition.
GALACTICA seems like a ChatGPT for scientific stuff.

Tried converting:

You are using a model of type opt to instantiate a model of type gptj. This is not supported for all configurations of models and can yield errors.

Obviously there needs to be valid vocab and added_token files... I am figuring out how galactica works...
@ggerganov
I get similar errors as above when trying to convert neox 20b. How do I create the added_tokens.json file?
python3 convert-h5-to-ggml.py gpt-neox-20b/

Did a quick hack so that added_tokens.json is not required:

I get this error:

I suppose there is no point in editing configs as neox model is different at the model level I guess.
EDIT
I after a small change the neox conversion seemed to work, but OOM killed it. So I changed it again to make it suitable to convert neo 125 m, but again I got a error:

I did some blind changes:
https://github.com/trholding/ggml/commits/master/examples/gpt-j/convert-h5-to-ggml.py
Model gets converted but in the end results in this error:

I think I should give up... I have probably no idea what I am doing...
Yeah, these models probably have different architecture compared to GPT-J, so it is not just a matter of converting the data. You have to also implement the missing layers and connect them correctly. Also there are probably some differences in the tokenizer.
Every model can be ported to ggml, but it requires some work. I guess it would be better if I try to make the codebase easier to understand and document it. This way other people might wish to contribute. Otherwise, it's too much work for a single developer.

Agreed, and a nice documentation with a Howto would be awesome :)
Hello, any updates on where this is? I am interested in working to port this model.
Looks like I won't have time to look into these in the near future. There are other more interesting models to port -- see the README
Refer https://github.com/NolanoOrg/cformers/ -> We have added GPT-J, BLOOM and support for NeoX models.
Please open an issue on what pre-compressed models would you want to be ported (with a python interface)
