Open WebUI : Install2024/06/04


Install Open WebUI which allows you to run LLM on Web UI.

Open WebUI can be easily installed with pip3, but as of June 2024, the default version of Python 3.12 on Ubuntu 24.04 and related modules are not fully compatible with the version required by Open WebUI (3.12.0a1,>=3.11), so in this example, we will start it in a container.


Install Podman, refer to here.


Install Ollama, refer to here.

[3] Pull and start the Open WebUI container image.
podman pull ghcr.io/open-webui/open-webui:main
