Installing a local LLM - Post 2 of 3

This post will discuss installing GPT4ALL from Nomic.io.

It worked reasonably easily.

I found it easier to install the app than the code.

1. Install Ubuntu linux version 22 (Jammy Jellyfish). 

a. Go to https://ubuntu.com/download 

b. Get the iso file

c. Copy it to a flash disk using Etcher (https://etcher.io) 

d. Insert flash disk, reboot, hit f2 on the keyboard; enter BIOS and tell your PC to boot off the flash disk. Take it from there. 

Step 2. Install gpt4all from github:


mkdir git

mkdir gpt4all

cd gpt4all

git clone https://github.com/ParisNeo/Gpt4All-webui

git clone https://github.com/nomic-ai/gpt4all


Step 3. Do this step

pip install 'pygpt4all==v1.0.1' --force-reinstall

sudo apt install libxcb-cursor0

Step 4. Install dev tools and pip

sudo apt-get install python3-dev

python3.10 -m pip install --upgrade pip

sudo apt install build-essential

cd Gpt4All-webui

python3.10 -m pip install -r requirements.txt


Step 5. Install hnswlib and chromadb

For some reason these do not seem to want to install unless you first upgrade pip and install build-essential which provides g++

cd git/gpt4all # if you are not already in that folder

sudo apt-get install python3-dev

python3.10 -m pip install --upgrade pip

sudo apt install build-essential

python3.10 -m pip install hnswlib

python3.10 -m pip install chromadb

then

python3.10 -m pip install chroma-migrate

chroma-migrate

python3.10 -m pip install -r requirements.txt


Step 6

Look for the app called 'chat' and run it. It should be in one of the git subfolders.

If that doesn't work, try get it precompiled from:


$ wget https://gpt4all.io/installers/gpt4all-installer-linux.run

$ chmod u+x gpt4all-installer-linux.run



Step 7: Run the installer:

$ ./gpt4all-installer-linux.run

$ sudo apt install libxcb-cursor0


However you still have to open it to download the LLM MODELS which are large files containing learning records of an AI that modeled/learnt a bunch of data. They are at least 2GB each so please do this on a fibre line. Different models have different levels of intelligence and knowledge. You have to experiment with them to see which are best. So far I think OpenAI's is best, but you can't get it. You have to make do with LLaMA from Facebook or Falcon or something else.

Recent Experiments testing ChatGPT's limits and some useful prompts

Introduction ChatGPT has a lot of people excited, but it deserves this level of excitement. It has a number of faults which I list below - some with workarounds - but in general it is amazingly good. It is absolutely not for having fun chatting to a robot, it's really more like a brilliant coworker who is incredibly stupid at some quite mundane tasks, but incredibly good at more tricky tasks. Summary of findings so far.  1. API vs Interactive Version - a caution 2. Coding Strengths and Weaknesses - be very careful but very useful anyway 3. Shell Scripting - amazingly good, probably what it's best at 4. Text Summarisation - fiddly but useful 5. Spreadsheet Analysis - annoying, maybe do by hand 6. Multi-Step Instruction Handling - very annoying 7. Spellchecking and writing style/grammar - ok overall but fiddly 8. File Compatibility and Formatting - not great 9. APA References from DOIs - good 10. Reference Accuracy - bad, double-check its work 11. Tone and Style Adaptations - ex...

Testing ChatGPT on coding - a script to make CSV to ICS

 So I gave ChatGPT a task of writing a CSV to ICS convertor, to take a spreadsheet of events and turn it into individual calendar file invitations. The idea is you can make a calendar with lots of event items in a spreadsheet, and then output ICS that you can just double-click to add to your calendar automatically. So here's the spreadsheet: "Event Name","Event Start Date","Event End Date","Event Start Time","Event End Time","event description or notes","URL applicable" "Meeting with John","2024-06-10","2024-06-10","09:00","10:00","Discuss project updates.","http://example.com" And here's the script ChatGPT made. It seems to get confused with things like Daylight Savings and/or Timezone but you can fix that manually. It took some debugging and I had to copy/paste my Mac's manpage for DATE into ChatGPT, but it got it eventually. The only...
