AI Smart Human Assistant Library

Project description

AISHA Lib: A High-Level Abstraction for Building AI Assistants

In the evolving landscape of artificial intelligence, the development of smart assistants has become increasingly prevalent. To streamline this process, the AISHA (AI Smart Human Assistant) Lib offers a high-level abstraction designed for creating AI assistants. This versatile library supports various large language models (LLMs) and different LLM backends, providing developers with a powerful and flexible toolset.

Environment

To create a Python virtual environment, use the command:

conda env create -f environment.yml

Installation

pip install aishalib

Supported Models

The following LLM models are supported:

  • Phi-3-medium-128k-instruct
  • c4ai-command-r-v01

LLM backends

The following LLM backends are supported:

  • Llama.cpp Server API

Telegram bot example

from aishalib.aishalib import Aisha
from telegram import Update
from telegram.ext import Application, MessageHandler, ContextTypes, filters

TG_TOKEN = "YOUR_TG_TOKEN"

SYSTEM_PROMPT = """
Ты умный бот помощник для общения в телеграме.
Ты общаешься в групповом чате с другими пользователями.
Ты отвечаешь на русском языке.
"""

SYSTEM_INJECTION = """
Последнее сообщение написал пользователь с идентификатором {user_id}.
Используй эти идентификаторы для того, чтобы различать пользователей.
Запрещено обращаться к пользователю по его идентификатору! Можно только по имени.
Если пользователь не представился спроси как его зовут.
Если исходя из контекста и смысла беседы это сообщение адресовано тебе или это общее сообщение для всех в чате то ты обязан на него ответить.
Если это сообщение адресовано другому пользователю, то напиши специальную команду "ignoring_message" в ответе.

with open("document.txt") as f:

Ниже представлен следующий текст по которому необходимо выполнять поиск.

Run Llama.CPP Server backend

llama.cpp/build/bin/server -m model_q5_k_m.gguf -ngl 99 -fa -c 4096 --host 0.0.0.0 --port 8000

Install CUDA toolkit for Llama.cpp compilation

Please note that the toolkit version must match the driver version. The driver version can be found using the nvidia-smi command. Аor example, to install toolkit for CUDA 12.2 you need to run the following commands:

CUDA_TOOLKIT_VERSION=12-2
wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2204/x86_64/cuda-keyring_1.1-1_all.deb
sudo dpkg -i cuda-keyring_1.1-1_all.deb
sudo apt update
sudo apt -y install cuda-toolkit-${CUDA_TOOLKIT_VERSION}
echo -e '
export CUDA_HOME=/usr/local/cuda
export PATH=${CUDA_HOME}/bin:${PATH}
export LD_LIBRARY_PATH=${CUDA_HOME}/lib64:$LD_LIBRARY_PATH
' >> ~/.bashrc
