NekoImageGallery

An online AI image search engine based on the Clip model and Qdrant vector database. Supports keyword search and similar image search.

中文文档

✨ Features

Use the Clip model to generate 768-dimensional vectors for each image as the basis for search. No need for manual annotation or classification, unlimited classification categories.
OCR Text search is supported, use PaddleOCR to extract text from images and use BERT to generate text vectors for search.
Use Qdrant vector database for efficient vector search.

✈️ Deployment

🖥️ Local Deployment

Choose a metadata storage method

Qdrant Database (Recommended)

In most cases, we recommend using the Qdrant database to store metadata. The Qdrant database provides efficient retrieval performance, flexible scalability, and better data security.

Please deploy the Qdrant database according to the Qdrant documentation. It is recommended to use Docker for deployment.

If you don't want to deploy Qdrant yourself, you can use the online service provided by Qdrant.

Local File Storage

Local file storage directly stores image metadata (including feature vectors, etc.) in a local SQLite database. It is only recommended for small-scale deployments or development deployments.

Local file storage does not require an additional database deployment process, but has the following disadvantages:

Local storage does not index and optimize vectors, so the time complexity of all searches is O(n). Therefore, if the data scale is large, the performance of search and indexing will decrease.
Using local file storage will make NekoImageGallery stateful, so it will lose horizontal scalability.
When you want to migrate to Qdrant database for storage, the indexed metadata may be difficult to migrate directly.

Deploy NekoImageGallery

Clone the project directory to your own PC or server, then checkout to a specific version tag (like v1.0.0).
It is highly recommended to install the dependencies required for this project in a Python venv virtual environment. Run the following command:
```
python -m venv .venv
. .venv/bin/activate
```
Install PyTorch. Follow the PyTorch documentation to install the torch version suitable for your system using pip.

If you want to use CUDA acceleration for inference, be sure to install a CUDA-supported PyTorch version in this step. After installation, you can use torch.cuda.is_available() to confirm whether CUDA is available.
Install other dependencies required for this project:
```
pip install -r requirements.txt
```
Modify the project configuration file inside config/, you can edit default.env directly, but it's recommended to create a new file named local.env and override the configuration in default.env.
Run this application:
```
python main.py
```
You can use --host to specify the IP address you want to bind to (default is 0.0.0.0) and --port to specify the port you want to bind to (default is 8000).
You can see all available commands and options by running python main.py --help.
(Optional) Deploy the front-end application: NekoImageGallery.App is a simple web front-end application for this project. If you want to deploy it, please refer to its deployment documentation.

🐋 Docker Deployment

About docker images

NekoImageGallery's docker image are built and released on Docker Hub, including serval variants:

Tags	Description	Latest Image Size
`edgeneko/neko-image-gallery:<version>` `edgeneko/neko-image-gallery:<version>-cuda` `edgeneko/neko-image-gallery:<version>-cuda12.1`	Supports GPU inferencing with CUDA12.1
`edgeneko/neko-image-gallery:<version>-cuda11.8`	Supports GPU inferencing with CUDA11.8
`edgeneko/neko-image-gallery:<version>-cpu`	Only supports CPU inferencing

Where <version> is the version number or version alias of NekoImageGallery, as follows:

Version	Description
`latest`	The latest stable version of NekoImageGallery
`v..` / `v.*`	The specific version number (correspond to Git tags)
`edge`	The latest development version of NekoImageGallery, may contain unstable features and breaking changes

In each image, we have bundled the necessary dependencies, openai/clip-vit-large-patch14 model weights, bert-base-chinese model weights and easy-paddle-ocr models to provide a complete and ready-to-use image.

The images uses /opt/NekoImageGallery/static as volume to store image files, mount it to your own volume or directory if local storage is required.

For configuration, we suggest using environment variables to override the default configuration. Secrets (like API tokens) can be provided by docker secrets.

Prepare `nvidia-container-runtime` (CUDA users only)

If you want to use CUDA acceleration, you need to install nvidia-container-runtime on your system. Please refer to the official documentation for installation.

Run the server

Download the docker-compose.yml file from repository.

# For cuda deployment (default)
wget https://raw.githubusercontent.com/hv0905/NekoImageGallery/master/docker-compose.yml
# For CPU-only deployment
wget https://raw.githubusercontent.com/hv0905/NekoImageGallery/master/docker-compose-cpu.yml && mv docker-compose-cpu.yml docker-compose.yml

Modify the docker-compose.yml file as needed

Run the following command to start the server:

# start in foreground
docker compose up
# start in background(detached mode)
docker compose up -d

Upload images to NekoImageGallery

There are serval ways to upload images to NekoImageGallery

Through the web interface: You can use the web interface to upload images to the server. The web interface is provided by NekoImageGallery.App. Make sure you have enabled the Admin API and set your Admin Token in the configuration file.
Through local indexing: This is suitable for local deployment or when the images you want to upload are already on the server. Use the following command to index your local image directory:
```
 python main.py local-index <path-to-your-image-directory>
```
The above command will recursively upload all images in the specified directory and its subdirectories to the server. You can also specify categories/starred for images you upload, see python main.py local-index --help for more information.
Through the API: You can use the upload API provided by NekoImageGallery to upload images. By using this method, the server can prevent saving the image files locally but only store their URLs and metadata.
Make sure you have enabled the Admin API and set your Admin Token in the configuration file.
This method is suitable for automated image uploading or sync NekoImageGallery with external systems. Checkout API documentation for more information.

📚 API Documentation

The API documentation is provided by FastAPI's built-in Swagger UI. You can access the API documentation by visiting the /docs or /redoc path of the server.
