Getting Started with Verba

You have three deployment options for Verba:

• Install via pip

pip install goldenverba

• Build from Source

git clone https://github.com/weaviate/Verba

pip install -e .

• Use Docker for Deployment

Prerequisites: If you're not using Docker, ensure that you have Python >=3.10.0,<3.13.0 installed on your system.

git clone https://github.com/weaviate/Verba

docker compose --env-file <your-env-file> up -d --build

If you're unfamiliar with Python and Virtual Environments, please read the python tutorial guidelines.

API Keys and Environment Variables

You can set all API keys in the Verba frontend, but to make your life easier, we can also prepare a .env file in which Verba will automatically look for the keys. Create a .env in the same directory you want to start Verba in. You can find an .env.example file in the goldenverba directory.

Make sure to only set environment variables you intend to use, environment variables with missing or incorrect values may lead to errors.

Below is a comprehensive list of the API keys and variables you may require:

Weaviate

Verba provides flexibility in connecting to Weaviate instances based on your needs. You have three options:

1. Local Deployment: Use Weaviate Embedded which runs locally on your device (except Windows, choose the Docker/Cloud Deployment)
2. Docker Deployment: Choose this option when you're running Verba's Dockerfile.
3. Cloud Deployment: Use an existing Weaviate instance hosted on WCD to run Verba

💻 Weaviate Embedded Embedded Weaviate is a deployment model that runs a Weaviate instance from your application code rather than from a stand-alone Weaviate server installation. When you run Verba in Local Deployment, it will setup and manage Embedded Weaviate in the background. Please note that Weaviate Embedded is not supported on Windows and is in Experimental Mode which can bring unexpected errors. We recommend using the Docker Deployment or Cloud Deployment instead. You can read more about Weaviate Embedded here.

🌩️ Weaviate Cloud Deployment (WCD)

If you prefer a cloud-based solution, Weaviate Cloud (WCD) offers a scalable, managed environment. Learn how to set up a cloud cluster and get the API keys by following the Weaviate Cluster Setup Guide.

🐳 Docker Deployment Another local alternative is deploying Weaviate using Docker. For more details, follow the How to install Verba with Docker section.

⚙️ Custom Weaviate Deployment

If you're hosting Weaviate yourself, you can use the Custom deployment option in Verba. This will allow you to specify the URL, PORT, and API key of your Weaviate instance.

Ollama

Verba supports Ollama models. Download and Install Ollama on your device (https://ollama.com/download). Make sure to install your preferred LLM using ollama run <model>.

Tested with llama3, llama3:70b and mistral. The bigger models generally perform better, but need more computational power.

Make sure Ollama Server runs in the background and that you don't ingest documents with different ollama models since their vector dimension can vary that will lead to errors

You can verify that by running the following command

ollama run llama3

Unstructured

Verba supports importing documents through Unstructured IO (e.g plain text, .pdf, .csv, and more). To use them you need the UNSTRUCTURED_API_KEY and UNSTRUCTURED_API_URL environment variable. You can get it from Unstructured

UNSTRUCTURED_API_URL is set to https://api.unstructuredapp.io/general/v0/general by default

AssemblyAI

Verba supports importing documents through AssemblyAI (audio files or audio from video files). To use them you need the ASSEMBLYAI_API_KEY environment variable. You can get it from AssemblyAI

OpenAI

Verba supports OpenAI Models such as Ada, GPT3, and GPT4. To use them, you need to specify the OPENAI_API_KEY environment variable. You can get it from OpenAI

You can also add a OPENAI_BASE_URL to use proxies such as LiteLLM (https://github.com/BerriAI/litellm)

OPENAI_BASE_URL=YOUR-OPENAI_BASE_URL

HuggingFace

If you want to use the HuggingFace Features, make sure to install the correct Verba package. It will install required packages to use the local embedding models. Please note that on startup, Verba will automatically download and install embedding models when used.

pip install goldenverba[huggingface]

or

pip install `.[huggingface]`

If you're using Docker, modify the Dockerfile accordingly

Groq

To use Groq LPUs as generation engine, you need to get an API key from Groq.

Although you can provide it in the graphical interface when Verba is up, it is recommended to specify it as GROQ_API_KEY environment variable before you launch the application.
It will allow you to choose the generation model in an up-to-date available models list.

How to install Verba with Docker

Docker is a set of platform-as-a-service products that use OS-level virtualization to deliver software in packages called containers. To get started with deploying Verba using Docker, follow the steps below. If you need more detailed instructions on Docker usage, check out the Docker Curriculum.

You can use docker pull semitechnologies/verba to pull the latest Verba Docker Image.

If you want to build the image yourself, you can do so by cloning the Verba repository and running docker build -t verba . inside the Verba directory.

0. Clone the Verba repos Ensure you have Git installed on your system. Then, open a terminal or command prompt and run the following command to clone the Verba repository:

git clone https://github.com/weaviate/Verba.git

1. Set necessary environment variables Make sure to set your required environment variables in the .env file. You can read more about how to set them up in the API Keys Section

2. Adjust the docker-compose file You can use the docker-compose.yml to add required environment variables under the verba service and can also adjust the Weaviate Docker settings to enable Authentification or change other settings of your database instance. You can read more about the Weaviate configuration in our docker-compose documentation. You can also uncomment the ollama service to use Ollama within the same docker compose.

Please make sure to only add environment variables that you really need.

2. Deploy using Docker With Docker installed and the Verba repository cloned, navigate to the directory containing the Docker Compose file in your terminal or command prompt. Run the following command to start the Verba application in detached mode, which allows it to run in the background:

docker compose up -d

docker compose --env-file goldenverba/.env up -d --build

This command will download the necessary Docker images, create containers, and start Verba. Remember, Docker must be installed on your system to use this method. For installation instructions and more details about Docker, visit the official Docker documentation.

4. Access Verba

• You can access your local Weaviate instance at localhost:8080

• You can access the Verba frontend at localhost:8000

If you want your Docker Instance to install a specific version of Verba you can edit the Dockerfile and change the installation line.

RUN pip install -e '.'

Verba Walkthrough

Select your Deployment

The first screen you'll see is the deployment screen. Here you can select between Local, Docker, Weaviate Cloud, or Custom deployment. The Local deployment is using Weaviate Embedded under the hood, which initializes a Weaviate instance behind the scenes. The Docker deployment is using a separate Weaviate instance that is running inside the same Docker network. The Weaviate Cloud deployment is using a Weaviate instance that is hosted on Weaviate Cloud Services (WCS). The Custom deployment allows you to specify your own Weaviate instance URL, PORT, and API key.

You can skip this part by setting the DEFAULT_DEPLOYMENT environment variable to Local, Docker, Weaviate, or Custom.

Import Your Data

First thing you need to do is to add your data. You can do this by clicking on Import Data and selecting either Add Files, Add Directory, or Add URL tab. Here you can add all your files that you want to ingest. You can then configure every file individually by selecting the file and clicking on Overview or Configure tab.

Query Your Data

With Data imported, you can use the Chat page to ask any related questions. You will receive relevant chunks that are semantically relevant to your question and an answer generated by your choosen model. You can configure the RAG pipeline under the Config tab.

Known Issues

• Weaviate Embeeded currently not working on Windows yet
  • Will be fixed in future versions, until then please use the Docker or WCS Deployment

FAQ

• Can I use pre-existing data from my Weaviate instance?

  • No, unfortunatley not. Verba requires the data to be in a specific format to work. And as of now, this is only possible by importing data through the Verba UI.

• Is Verba Multi-Lingual?

  • This depends on your choosen Embedding and Generation Model whether they support multi-lingual data.

• Can I use my Ollama Server with the Verba Docker?

  • Yes, you can! Make sure the URL is set to: OLLAMA_URL=http://host.docker.internal:11434
  • If you're running on Linux, you might need to get the IP Gateway of the Ollama server: OLLAMA_URL="http://YOUR-IP-OF-OLLAMA:11434"

• How to clear Weaviate Embedded Storage?

  • You'll find the stored data here: ~/.local/share/weaviate

• How can I specify the port?

  • You can use the port and host flag verba start --port 9000 --host 0.0.0.0

• Can multiple users use Verba at the same time? How about role based access?

  • Verba is designed and optimized for single user usage only. There are no plans on supporting multiple users or role based access in the near future.

• Does Verba offer a API endpoint to use externally?

  • No, right now Verba does not offer any useful API endpoints to interact with the application. The current FastAPI setup is optimized for the internal communication between the frontend and backend. It is not recommended to use it as a API endpoint. There are plans to add user-friendly
