A git error occurred on the "Hello RAG" page

General

Hello, all.

I noticed that YugabyteDB supports AI functions.
I was going to try it right away,

There seems to be no next repository.

git clone https://github.com/YugabyteDB-Samples/hello_rag.git
...
remote: Repository not found.
fatal: repository 'https://github.com/YugabyteDB-Samples/hello_rag.git/' not found

Also, the next one didn’t work well in my environment, so I put the psycopg2-binary in the error message with pip.

pip install psycopg2

Is this document not maintained?

When I tried it, there was no Git repository on this page. Isn’t it a private repository?

$ git clone https://github.com/YugabyteDB-Samples/yugabytedb-localai-programming-language-search.git
Cloning into 'yugabytedb-localai-programming-language-search'...
remote: Repository not found.
fatal: repository 'https://github.com/YugabyteDB-Samples/yugabytedb-localai-programming-language-search.git/' not found

Hi thanks for raising this, I see they are indeed still private, we’ll get that fixed.

Can you explain the other error you had in this part?

YugabyteDB is running on AlmaLinux 9.6.

I tried several times and it didn’t work, but I found that I could install it properly if I set it up as follows. The problem that psycopg2 could not be installed has been resolved.

sudo dnf module switch-to postgresql:15
sudo dnf install -y postgresql-devel gcc make python3.11-devel

python3.11 -m venv ./env
source ./env/bin/activate 

(env) [almalinux@ml110gen9 hoge]$ pip install psycopg2

  DEPRECATION: psycopg2 is being installed using the legacy 'setup.py install' method, because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the '--use-pep517' option. Discussion can be found at https://github.com/pypa/pip/issues/8559

By the way, when it didn’t work, the following error occurred. The python3.11-devel package should have been installed.

Or maybe it’s because I was using an older generation server.

      It appears you are missing some prerequisite to build the package from source.
      
      You may install a binary package by installing 'psycopg2-binary' from PyPI.
      If you want to install psycopg2 from source, please install the packages
      required for the build and try again.
      
      For further information please check the 'doc/src/install.rst' file (also at
      <https://www.psycopg.org/docs/install.html>).

  note: This error originates from a subprocess, and is likely not a problem with pip.

No, it’s that psycopg2 is compiling from source so it needs the “-devel” packages. Using psycopg2-binary should work though without needing to install those Installation — Psycopg 2.9.10 documentation
