Bug: Failed to load model

What happened?

Hi guys. I have got a problem after I compile Llama on my machine. It built properly, but when I try to run it, it is looking for a file don't even exist (a model).

Is it normal ?

You should download a model firstly, mate.

If you check your models dir, probably you cannot find llama-7b.

[Fulgurance]

Sorry I am starting with llama. So I clone that model for example: https://huggingface.co/THUDM/glm-4-9b

But I don't see any .gguf file. I guess I have to generate it ? How I am suppose to do that ?

[MartinRepo]

For this kind of model, you need to convert it to gguf, use convert-hf-to-gguf.py to do it, you can find details in documentation.

However, if you just want a quick start, have a try of "quantised-ready" model, like this: https://huggingface.co/TheBloke/Llama-2-13B-chat-GGUF

[Fulgurance]

So I tried to run your model. But I get an error again.

[MartinRepo]

On huggingface, there is a demo code for llama.cpp (at the top-right corner "Use this model" button). Probably have a try: ./llama-cli --hf-repo "TheBloke/Llama-2-13B-chat-GGUF" -m llama-2-13b-chat.Q2_K.gguf -p "How are you?" -n 128

Okay I understood how to download now.

So I have a question. Which model do you recommend me ? Because I would like to integrant an IA assistant inside the linux distribution I am making, and I would like to teach the assistant how to manage the system with my tools. The one you gave me is good you think for that ? Basically I would like to this assistant to be able to run command.

I would like as well when the AI answer to stop talking too much xD. How can I allow the AI to run some bash command in my system ?

[Fulgurance]

Because the terminal is always showing extra text, I want to avoid that (with im_end and tips):

> Hello
Hi there! How can I help you today?
<|im_end|>

In this example, the

TBH, I don't think you're going to get a good answer to that question here. You're clearly new to this stuff and have a lot of homework to do. What you want to do is extremely complicated and probably well out of reach for your skill level. My advice is to start doing a lot of research and attempt far easier projects first. You're asking how to design a car when you don't know how to drive. Also, this is not the appropriate place for these questions. I figured this comment would be more helpful to you than silence. Good luck

I understood how to do now no worries 👍 I asked somewhere else with people more able to explain. It's not that much complicate...

Let me know when you're done so I can check it out!
