DeepSeek-v3.1

For local runs, I made some GGUFs! You need around RAM + VRAM >= 250GB for good perf for dynamic 2bit (2bit MoE, 6-8bit rest) - can also do SSD offloading but it'll be slow.

./llama.cpp/llama-cli -hf unsloth/DeepSeek-V3.1-GGUF:UD-Q2_K_XL -ngl 99 --jinja -ot ".ffn_.*_exps.=CPU"

More details on running + optimal params here: https://docs.unsloth.ai/basics/deepseek-v3.1

By the way, I'm wondering why unsloth (a goddamn python library) tries to run apt-get with sudo (and fails on my nixos). Like how tf we are supposed to use that?

Oh hey I'm assuming this is for conversion to GGUF after a finetune? If you need to quantize to GGUF Q4_K_M, we have to compile llama.cpp, hence apt-get and compiling llama.cpp within a Python shell.

There is a way to convert to Q8_0, BF16, F16 without compiling llama.cpp, and it's enabled if you use `FastModel` and not on `FastLanguageModel`

Essentially I try to do `sudo apt-get` if it fails then `apt-get` and if all fails, it just fails. We need `build-essential cmake curl libcurl4-openssl-dev`

It seems Unsloth is useful and popular, and you seem responsive and helpful. I'd be down to try to improve this and maybe package Unsloth for Nix as well, if you're up for reviewing and answering questions; seems fun.

Imo it's best to just depend on the required fork of llama.cpp at build time (or not) according to some configuration. Installing things at runtime is nuts (especially if it means modifying the existing install path). But if you don't want to do that, I think this would also be an improvement:

  - see if llama.cpp is on the PATH and already has the requisite features
  - if not, check /etc/os-release to determine distro
  - if unavailable, guess distro class based on the presence of high-level package managers (apt, dnf, yum, zypper, pacman) on the PATH
  - bail, explain the problem to the user, give copy/paste-friendly instructions at the end of we managed to figure out where we're running

Is either sort of change potentially agreeable enough that you'd be happy to review it?

Thanks for the suggestions! Apologies again I'm pretty bad at packaging, so hence the current setup.

1. So I added a `check_llama_cpp` which checks if llama.cpp does exist and it'll use the prebuilt one https://github.com/unslothai/unsloth-zoo/blob/main/unsloth_z...

2. Yes I like the idea of determining distro

3. Agreed on bailing - I was also thinking if doing a Python input() with a 30 second waiting period for apt-get if that's ok? We tell the user we will apt-get some packages (only if apt exists) (no sudo), and after 30 seconds, it'll just error out

4. I will remove sudo immediately (ie now), and temporarily just do (3)

But more than happy to fix this asap - again sorry on me being dumb

It shouldn't install any packages itself. Just print out a message about the missing packages and your guess of the command to install them, then exit. That way users can run the command themselves if it's appropriate or add the packages to their container build or whatever. People set up machines in a lot of different ways, and automatically installing things is going to mess that up.

This is an edge case optimization at the cost of 95% of users.
