-# LocalAI Backend Architecture
-
-This directory contains the core backend infrastructure for LocalAI, including the gRPC protocol definition, multi-language Dockerfiles, and language-specific backend implementations.
-
-## Overview
-
-LocalAI uses a unified gRPC-based architecture that allows different programming languages to implement AI backends while maintaining consistent interfaces and capabilities. The backend system supports multiple hardware acceleration targets and provides a standardized way to integrate various AI models and frameworks.
-
-## Architecture Components
-
-### 1. Protocol Definition (`backend.proto`)
-
-The `backend.proto` file defines the gRPC service interface that all backends must implement. This ensures consistency across different language implementations and provides a contract for communication between LocalAI core and backend services.
-
-#### Core Services
-
-- **Text Generation**: `Predict`, `PredictStream` for LLM inference
-- **Embeddings**: `Embedding` for text vectorization
-- **Image Generation**: `GenerateImage` for stable diffusion and image models
-- **Audio Processing**: `AudioTranscription`, `TTS`, `SoundGeneration`
-- **Video Generation**: `GenerateVideo` for video synthesis
-- **Object Detection**: `Detect` for computer vision tasks
-- **Vector Storage**: `StoresSet`, `StoresGet`, `StoresFind` for RAG operations
-- **Reranking**: `Rerank` for document relevance scoring
-- **Voice Activity Detection**: `VAD` for audio segmentation
-
-#### Key Message Types
-
-- **`PredictOptions`**: Comprehensive configuration for text generation
-- **`ModelOptions`**: Model loading and configuration parameters
-- **`Result`**: Standardized response format
-- **`StatusResponse`**: Backend health and memory usage information
-
-### 2. Multi-Language Dockerfiles
-
-The backend system provides language-specific Dockerfiles that handle the build environment and dependencies for different programming languages:
-
-- `Dockerfile.python`
-- `Dockerfile.golang`
-- `Dockerfile.llama-cpp`
-
-### 3. Language-Specific Implementations
-
-#### Python Backends (`python/`)
-- **transformers**: Hugging Face Transformers framework
-- **vllm**: High-performance LLM inference
-- **mlx**: Apple Silicon optimization
-- **diffusers**: Stable Diffusion models
-- **Audio**: bark, coqui, faster-whisper, kitten-tts
-- **Vision**: mlx-vlm, rfdetr
-- **Specialized**: rerankers, chatterbox, kokoro
-
-#### Go Backends (`go/`)
-- **whisper**: OpenAI Whisper speech recognition in Go with GGML cpp backend (whisper.cpp)
-- **stablediffusion-ggml**: Stable Diffusion in Go with GGML Cpp backend
-- **huggingface**: Hugging Face model integration
-- **piper**: Text-to-speech synthesis Golang with C bindings using rhaspy/piper
-- **bark-cpp**: Bark TTS models Golang with Cpp bindings
-- **local-store**: Vector storage backend
-
-#### C++ Backends (`cpp/`)
-- **llama-cpp**: Llama.cpp integration
-- **grpc**: GRPC utilities and helpers
-

-
-- **Metadata**: Name, description, license, icons
-- **Capabilities**: Hardware targets and optimization profiles
-- **Tags**: Categorization for discovery
-- **URLs**: Source code and documentation links
-

-
-For ARM64/Mac builds, docker can't be used, and the makefile in the respective backend has to be used.
-
-### Build Types
-
-- **`cpu`**: CPU-only optimization
-- **`cublas11`**: CUDA 11.x with cuBLAS
-- **`cublas12`**: CUDA 12.x with cuBLAS
-- **`hipblas`**: ROCm with rocBLAS
-- **`intel`**: Intel oneAPI optimization
-- **`vulkan`**: Vulkan-based acceleration
-- **`metal`**: Apple Metal optimization
-
-## Backend Development
-
-### Creating a New Backend
-
-1. **Choose Language**: Select Python, Go, or C++ based on requirements
-2. **Implement Interface**: Implement the gRPC service defined in `backend.proto`
-3. **Add Dependencies**: Create appropriate requirements files
-4. **Configure Build**: Set up Dockerfile and build scripts
-5. **Register Backend**: Add entry to `index.yaml`
-6. **Test Integration**: Verify gRPC communication and functionality
-
-### Backend Structure
-
-```
-backend-name/
-├── backend.py/go/cpp    # Main implementation
-├── requirements.txt      # Dependencies
-├── Dockerfile           # Build configuration
-├── install.sh           # Installation script
-├── run.sh              # Execution script
-├── test.sh             # Test script
-└── README.md           # Backend documentation
-```
-
-### Required gRPC Methods
-
-At minimum, backends must implement:
-- `Health()` - Service health check
-- `LoadModel()` - Model loading and initialization
-- `Predict()` - Main inference endpoint
-- `Status()` - Backend status and metrics
-
-## Integration with LocalAI Core
-
-Backends communicate with LocalAI core through gRPC:
-
-1. **Service Discovery**: Core discovers available backends
-2. **Model Loading**: Core requests model loading via `LoadModel`
-3. **Inference**: Core sends requests via `Predict` or specialized endpoints
-4. **Streaming**: Core handles streaming responses for real-time generation
-5. **Monitoring**: Core tracks backend health and performance
-
-## Performance Optimization
-
-### Memory Management
-- **Model Caching**: Efficient model loading and caching
-- **Batch Processing**: Optimize for multiple concurrent requests
-- **Memory Pinning**: GPU memory optimization for CUDA/ROCm
-
-### Hardware Utilization
-- **Multi-GPU**: Support for tensor parallelism
-- **Mixed Precision**: FP16/BF16 for memory efficiency
-- **Kernel Fusion**: Optimized CUDA/ROCm kernels
-
-## Troubleshooting
-
-### Common Issues
-
-1. **GRPC Connection**: Verify backend service is running and accessible
-2. **Model Loading**: Check model paths and dependencies
-3. **Hardware Detection**: Ensure appropriate drivers and libraries
-4. **Memory Issues**: Monitor GPU memory usage and model sizes
-
-## Contributing
-
-When contributing to the backend system:
-
-1. **Follow Protocol**: Implement the exact gRPC interface
-2. **Add Tests**: Include comprehensive test coverage
-3. **Document**: Provide clear usage examples
-4. **Optimize**: Consider performance and resource usage
-5. **Validate**: Test across different hardware targets

-# Python Backends for LocalAI
+# Common commands about conda environment
 
-This directory contains Python-based AI backends for LocalAI, providing support for various AI models and hardware acceleration targets.
+## Create a new empty conda environment
 
-## Overview
+```
+conda create --name <env-name> python=<your version> -y
 
-The Python backends use a unified build system based on `libbackend.sh` that provides:
-- **Automatic virtual environment management** with support for both `uv` and `pip`
-- **Hardware-specific dependency installation** (CPU, CUDA, Intel, MLX, etc.)
-- **Portable Python support** for standalone deployments
-- **Consistent backend execution** across different environments
-
-## Available Backends
-
-### Core AI Models
-- **transformers** - Hugging Face Transformers framework (PyTorch-based)
-- **vllm** - High-performance LLM inference engine
-- **mlx** - Apple Silicon optimized ML framework
-- **exllama2** - ExLlama2 quantized models
-
-### Audio & Speech
-- **bark** - Text-to-speech synthesis
-- **coqui** - Coqui TTS models
-- **faster-whisper** - Fast Whisper speech recognition
-- **kitten-tts** - Lightweight TTS
-- **mlx-audio** - Apple Silicon audio processing
-- **chatterbox** - TTS model
-- **kokoro** - TTS models
-
-### Computer Vision
-- **diffusers** - Stable Diffusion and image generation
-- **mlx-vlm** - Vision-language models for Apple Silicon
-- **rfdetr** - Object detection models
-
-### Specialized
-
-- **rerankers** - Text reranking models
-
-## Quick Start
-
-### Prerequisites
-- Python 3.10+ (default: 3.10.18)
-- `uv` package manager (recommended) or `pip`
-- Appropriate hardware drivers for your target (CUDA, Intel, etc.)
-
-### Installation
-
-Each backend can be installed individually:
-
-```bash
-# Navigate to a specific backend
-cd backend/python/transformers
-
-# Install dependencies
-make transformers
-# or
-bash install.sh
-
-# Run the backend
-make run
-# or
-bash run.sh
+conda create --name autogptq python=3.11 -y
 ```
 
-### Using the Unified Build System
+## To activate the environment
 
-The `libbackend.sh` script provides consistent commands across all backends:
-
-```bash
-# Source the library in your backend script
-source $(dirname $0)/../common/libbackend.sh
-
-# Install requirements (automatically handles hardware detection)
-installRequirements
-
-# Start the backend server
-startBackend $@
-
-# Run tests
-runUnittests
+As of conda 4.4
+```
+conda activate autogptq
 ```
 
-## Hardware Targets
+The conda version older than 4.4
 
-The build system automatically detects and configures for different hardware:
-
-- **CPU** - Standard CPU-only builds
-- **CUDA** - NVIDIA GPU acceleration (supports CUDA 11/12)
-- **Intel** - Intel XPU/GPU optimization
-- **MLX** - Apple Silicon (M1/M2/M3) optimization
-- **HIP** - AMD GPU acceleration
-
-### Target-Specific Requirements
-
-Backends can specify hardware-specific dependencies:
-- `requirements.txt` - Base requirements
-- `requirements-cpu.txt` - CPU-specific packages
-- `requirements-cublas11.txt` - CUDA 11 packages
-- `requirements-cublas12.txt` - CUDA 12 packages
-- `requirements-intel.txt` - Intel-optimized packages
-- `requirements-mps.txt` - Apple Silicon packages
-
-## Configuration Options
-
-### Environment Variables
-
-- `PYTHON_VERSION` - Python version (default: 3.10)
-- `PYTHON_PATCH` - Python patch version (default: 18)
-- `BUILD_TYPE` - Force specific build target
-- `USE_PIP` - Use pip instead of uv (default: false)
-- `PORTABLE_PYTHON` - Enable portable Python builds
-- `LIMIT_TARGETS` - Restrict backend to specific targets
-
-### Example: CUDA 12 Only Backend
-
-```bash
-# In your backend script
-LIMIT_TARGETS="cublas12"
-source $(dirname $0)/../common/libbackend.sh
+```
+source activate autogptq
 ```
 
-### Example: Intel-Optimized Backend
+## Install the packages to your environment
 
-```bash
-# In your backend script
-LIMIT_TARGETS="intel"
-source $(dirname $0)/../common/libbackend.sh
+Sometimes you need to install the packages from the conda-forge channel
+
+By using `conda`
+```
+conda install <your-package-name>
+
+conda install -c conda-forge <your package-name>
 ```
 
-## Development
-
-### Adding a New Backend
-
-1. Create a new directory in `backend/python/`
-2. Copy the template structure from `common/template/`
-3. Implement your `backend.py` with the required gRPC interface
-4. Add appropriate requirements files for your target hardware
-5. Use `libbackend.sh` for consistent build and execution
-
-### Testing
-
-```bash
-# Run backend tests
-make test
-# or
-bash test.sh
+Or by using `pip`
 ```
-
-### Building
-
-```bash
-# Install dependencies
-make <backend-name>
-
-# Clean build artifacts
-make clean
+pip install <your-package-name>
 ```
-
-## Architecture
-
-Each backend follows a consistent structure:
-```
-backend-name/
-├── backend.py          # Main backend implementation
-├── requirements.txt    # Base dependencies
-├── requirements-*.txt  # Hardware-specific dependencies
-├── install.sh         # Installation script
-├── run.sh            # Execution script
-├── test.sh           # Test script
-├── Makefile          # Build targets
-└── test.py           # Unit tests
-```
-
-## Troubleshooting
-
-### Common Issues
-
-1. **Missing dependencies**: Ensure all requirements files are properly configured
-2. **Hardware detection**: Check that `BUILD_TYPE` matches your system
-3. **Python version**: Verify Python 3.10+ is available
-4. **Virtual environment**: Use `ensureVenv` to create/activate environments
-
-## Contributing
-
-When adding new backends or modifying existing ones:
-1. Follow the established directory structure
-2. Use `libbackend.sh` for consistent behavior
-3. Include appropriate requirements files for all target hardware
-4. Add comprehensive tests
-5. Update this README if adding new backend types
