How to fix: ValueError: Failed to detect model architecture

[VenominousX]

Hi,

I'm currently learning the basics of creating my own AI models. I've already managed to get as far as the .pth and .safetensors files, but I'm stuck when it comes to converting .safetensors to gguf.
When I run the convert_hf_to_gguf.py script, I get the following error:

ValueError: Failed to detect model architecture

The Config.json file must contain a “model_type” key, but I don't know which of the options are allowed for a custom model.

I am using a GPT2 Tiktoken, but when I enter “gpt2” as the model_type, I also get the error.

What can I do to prepare a self-built model so that I can use it in Ollama?

It's probably a stupid question, but I'm stuck here^^.

Best regards
