### Installation of optional dependencies
Explorer depends on external libraries for some of its functionality. These are automatically installed on usage. To manually install these dependencies, use the following command:
```bash
pip install ultralytics[explorer]
```
!!! tip
Explorer works on embedding/semantic search & SQL querying and is powered by [LanceDB](https://lancedb.com/) serverless vector database. Unlike traditional in-memory DBs, it is persisted on disk without sacrificing performance, so you can scale locally to large datasets like COCO without running out of memory.
### Explorer API
This is a Python API for Exploring your datasets. It also powers the GUI Explorer. You can use this to create your own exploratory notebooks or scripts to get insights into your datasets.
Learn more about the Explorer API [here](api.md).
## GUI Explorer Usage
The GUI demo runs in your browser allowing you to create [embeddings](https://www.ultralytics.com/glossary/embeddings) for your dataset and search for similar images, run SQL queries and perform semantic search. It can be run using the following command:
```bash
yolo explorer
```
!!! note
Ask AI feature works using OpenAI, so you'll be prompted to set the api key for OpenAI when you first run the GUI.
You can set it like this - `yolo settings openai_api_key="..."`
## FAQ

### What is the Ask AI feature in Ultralytics Explorer?
The Ask AI feature in Ultralytics Explorer allows users to interact with their datasets using natural language queries. Powered by OpenAI, this feature enables you to ask complex questions and receive insightful answers without needing to write SQL queries or similar commands. To use this feature, you'll need to set your OpenAI API key the first time you run the GUI:
```bash
yolo settings openai_api_key="YOUR_API_KEY"
```
For more on this feature and how to integrate it, see our [GUI Explorer Usage](#gui-explorer-usage) section.
### Can I run Ultralytics Explorer in Google Colab?
Yes, Ultralytics Explorer can be run in Google Colab, providing a convenient and powerful environment for dataset exploration. You can start by opening the provided Colab notebook, which is pre-configured with all the necessary settings:
This setup allows you to explore your datasets fully, taking advantage of Google's cloud resources. Learn more in our [Google Colab Guide](../../integrations/google-colab.md).
