Seeking Ubuntu Help

by gmcaplan＠gmcaplan.org

I hope one or more of you can help me. I upgraded today from Ubuntu 18.04 LTS to 20.04 LTS on my desktop computer. (I know I am way behind, but I can do this only in the summer etc., etc.) I used the built-in Ubuntu update feature. It worked better than I expected and took less that two hours. The data backups I did ahead of time took much longer. Anyway, 20.04 is running but I have two problems. Number One: Many terminal commands give this message: Errors were encountered while processing: linux-image-4.15.0-212-generic Processing was halted because there were too many errors. W: Can not find PkgVer for 'linux-image-extra-4.4.0-122-generic' E: Sub-process /usr/bin/dpkg returned an error code (1) In particular, here is what happens when I try to remove 4.4.0-212. sudo apt-get --purge remove linux-image-extra-4.4.0-212-generic Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package linux-image-extra-4.4.0-212-generic E: Couldn't find any package by glob 'linux-image-extra-4.4.0-212-generic' E: Couldn't find any package by regex 'linux-image-extra-4.4.0-212-generic' Number Two: I cannot get audio out of Line Out to my speakers. And I cannot get audio into Line In to make recordings. I *do* get audio from the audio output on my HDMI monitor. This might be related to the need for codecs, but when I try various terminal commands to load more codecs, I get problem Number 1 ! Some of what I read on the Web mentions tex files that could cause Number 1. I do have TeXstudio installed. I tried to uninstall texstudio and texlive, but when I do that, I get the message ant Number One! I'd appreciate any help or suggestions. Thank you.

Re: LLM's and graphical interfaces.

by John Stoffel

Jansen, Thanks for posting this tutorial! I don't have any nVidia hardware at home so I'll have to try and spin this up in the cloud somewhere. Won't get much of a chance to poke at this until the next meeting. Will we see you and your wife there by any chance? John

Re: LLM's and graphical interfaces.

I made a mild how-to, for replicating my setup. Please note that the Nvidia driver setup is a SEPARATE "huge deal" that is out of scope for this how-to. You'll know the system is working if you see action in response to a prompt while running nvtop: I run the open-webui stack found here: https://github.com/open-webui/open-webui In order to have ollama (the LLM backend) available for my other fun projects and to ensure that the GPU is utilized by ollama, make sure you run the api and gpu compose files: docker compose -f docker-compose.yaml -f docker-compose.api.yaml -f docker-compose.gpu.yaml up -d --build I've catted my own versions of these files below: (base) house@chonkers:~/open-webui$ cat docker-compose.gpu.yaml services: ollama: # GPU support deploy: resources: reservations: devices: - driver: ${OLLAMA_GPU_DRIVER-nvidia} count: all capabilities: - gpu (base) house@chonkers:~/open-webui$ cat docker-compose.api.yaml version: '3.8' services: ollama: # Expose Ollama API outside the container stack ports: - ${OLLAMA_WEBAPI_PORT-11434}:11434 (base) house@chonkers:~/open-webui$ cat docker-compose.yaml version: '3.8' services: ollama: volumes: - ollama:/root/.ollama container_name: ollama pull_policy: always tty: true restart: unless-stopped image: ollama/ollama:${OLLAMA_DOCKER_TAG-latest} open-webui: build: context: . args: OLLAMA_BASE_URL: '/ollama' dockerfile: Dockerfile image: ghcr.io/open-webui/open-webui:${WEBUI_DOCKER_TAG-main} container_name: open-webui volumes: - open-webui:/app/backend/data depends_on: - ollama ports: - 3131:8080 environment: - 'OLLAMA_BASE_URL=http://ollama:11434' - 'WEBUI_SECRET_KEY=' extra_hosts: - host.docker.internal:host-gateway restart: unless-stopped volumes: ollama: {} open-webui: {} (base) house@chonkers:~/open-webui$ On Thu, Jun 13, 2024 at 11:48 AM John Stoffel <john(a)stoffel.org> wrote: > > Thanks for sending out this info Jansen, now to find time to actually > play with this stuff! > > > (can this email address be added to the mailing list?) > > > the self-hosted webui i use is here: > > https://github.com/open-webui/open-webui > > > ollama! > > https://github.com/ollama/ollama > > > here's the docker for ollama: > > https://hub.docker.com/r/ollama/ollama > > > On Tue, May 14, 2024 at 5:32 PM Kevin Harrington < > mad.hephaestus(a)gmail.com> wrote: > > > ---------- Forwarded message --------- > > From: Tim Keller via WLUG <wlug(a)lists.wlug.org> > > Date: Tue, May 14, 2024, 4:49 PM > > Subject: [WLUG] LLM's and graphical interfaces. > > To: Worcester Linux Users' Group General Discussion < > wlug(a)lists.wlug.org> > > Cc: Tim Keller <turbofx(a)gmail.com> > > > A couple meetings ago Jansen showed up a really cool graphical > interface for LLM. > > > Does anybody remember what it was? > > > Thanks, > > Tim. > > > -- > > I am leery of the allegiances of any politician who refers to their > constituents as > > "consumers". > > _______________________________________________ > > WLUG mailing list -- wlug(a)lists.wlug.org > > To unsubscribe send an email to wlug-leave(a)lists.wlug.org > > Create Account: https://wlug.mailman3.com/accounts/signup/ > > Change Settings: > https://wlug.mailman3.com/postorius/lists/wlug.lists.wlug.org/ > > Web Forum/Archive: > > > https://wlug.mailman3.com/hyperkitty/list/wlug@lists.wlug.org/message/XVOQB… > > _______________________________________________ > > WLUG mailing list -- wlug(a)lists.wlug.org > > To unsubscribe send an email to wlug-leave(a)lists.wlug.org > > Create Account: https://wlug.mailman3.com/accounts/signup/ > > Change Settings: > https://wlug.mailman3.com/postorius/lists/wlug.lists.wlug.org/ > > Web Forum/Archive: > https://wlug.mailman3.com/hyperkitty/list/wlug@lists.wlug.org/message/4ZQIW… >

This is for Brendan! Running VMs with GPU pass through

by John Stoffel

I haven't spent any time on this, but saw this article and thought of Brendan right off the bat. https://www.theregister.com/2024/06/19/proxmox_xcp_ng_gpu_passthrough/ This might be what he needs to run stuff at home on his GPU pass-through attempts. John

Re: Reminder: Meeting June 13th 2024 at 7PM! Topic: Your own personal LLM!

by John Stoffel

Hi all, I think we had a good meeting last night, it was certainly neat seeing how well ollama2 and ollama3 are at answering questions. It was also interesting to see how it could start going off the rails a little bit when asked interesting questions, because it couldn't (in my mind!) reason about things properly. Can you tell I'm an AI skeptic in some ways? It will make big changes at some point, but I don't think it will be as much as people think right away. It's still on the hype phase, and we haven't gotten to the reality crash yet. So hopefully we'll get some more details posted so we can all play around with ollama3 on our own systems. It's a bummer I can't use my AMD GPUs since that's all I have, no nVidia stuff at all in my house. And for next month, what do people want to talk about? I can try to resurrect my talk on KiCad, updated for v8 that was released ealier this year. Or I can talk about 'duc' which is the software package I help maintain. It's for indexing large large filesystems and displaying disk usage via CLI, GUI or web pages. It's really useful for when you have a 12Tb filesystem with 30 million files, because plain 'du' just takes way too long. https://github.com/zevv/duc is where you can find it. It's been quiet for a long time, but I've been recently getting ready to update and push out a new release. Hopefully this month if I'm lucky! John

Reminder: Meeting June 13th 2024 at 7PM! Topic: Your own personal LLM!

by Tim Keller

Hey Gang! We've got a meeting tomorrow!! Date/Time: June 13th 2024 @ 7pm. Location: Technocopia, 44 Portland St, 6th floor, Worcester MA. Virtual Location: (back to the old haunt) https://meet.jit.si/WlugMA <https://meet.jit.si/WlugMA> Considering how much AI has been in the news, I thought it would be cool to do a talk/demo about setting up your own personal Large Language Model! I'll either use my laptop of scrounge up a piece of good enough hardware to show it off.. hell I could even spin up a droplet and run it somewhere.. we'll figure that out. Jansen sent me some links to the cool stuff he uses and I'll definitely be leaning on his expertise and others. Here's what he wrote: the self-hosted webui i use is here: https://github.com/open-webui/open-webui ollama! https://github.com/ollama/ollama here's the docker for ollama: https://hub.docker.com/r/ollama/ollama I've experimented with the ollama models and they're cool. As usual we'll nerd out, wrestle with some LLM stuff and have a great time. Afterwards we'll head off to the Boyton or somewhere else for some dinner and keep the geekery in full swing. I'll bring some snacks and refreshments as well. Later, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

It takes me a while to remember where the interface for uploading ISO files is whenever I need to use it. That's one thing that Scale Computing does well. The interface for uploading images is pretty straightforward, and it will convert images from various formats for you automatically.
