Installing a local LLM - post 3 of 3

This is a post on getting PrivateGPT to work.

1. Install git repo

Firstly let's assume you have already downloaded and installed PrivateGPT in your local git repository. If that means nothing to you, open your terminal (Linux) and type:

mkdir git

cd git

git clone https://github.com/imartinez/privateGPT


2. Make sure python and libraries are working

Mostly if you install the components it just works, however Ubuntu 22 comes with a version of g++ and friends that it doesn't like. So you have to use Python 3.10 specifically and then run these commands:

cd git/privateGPT

sudo apt-get install python3.10 # please only use this version

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

sudo apt install libxcb-cursor0


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



3. Test it

Copy some PDFs or text files into the folder "source_documents"

cp ~/*.pdf ~/*.txt source_documents/ 


run the ingest script to read the files:

python3.10 ingest.py


run the privateGPT script

python3.10 privategpt.py

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...
