Important Notes

Before submitting a bug report: Please check the Issues or Discussions section to see if a similar issue or feature request has already been posted. It's likely we're already tracking it! If you’re unsure, start a discussion post first. This will help us efficiently focus on improving the project.
Collaborate respectfully: We value a constructive attitude, so please be mindful of your communication. If negativity is part of your approach, our capacity to engage may be limited. We’re here to help if you’re open to learning and communicating positively. Remember, Open WebUI is a volunteer-driven project managed by a single maintainer and supported by contributors who also have full-time jobs. We appreciate your time and ask that you respect ours.
Contributing: If you encounter an issue, we highly encourage you to submit a pull request or fork the project. We actively work to prevent contributor burnout to maintain the quality and continuity of Open WebUI.
Bug reproducibility: If a bug cannot be reproduced with a :main or :dev Docker setup, or a pip install with Python 3.11, it may require additional help from the community. In such cases, we will move it to the "issues" Discussions section due to our limited resources. We encourage the community to assist with these issues. Remember, it’s not that the issue doesn’t exist; we need your help!

Installation Method

Docker

Environment

Open WebUI Version: v0.5.6
Operating System: Rocky Linux 9

Confirmation:

I am on the latest version of both Open WebUI and Ollama.
I have included the Docker container logs.
I have provided the exact steps to reproduce the bug in the "Steps to Reproduce" section below.

Expected Behavior:

Adding a python library to the requirements comment should install it.

Actual Behavior:

This works when initially adding a tool, but is not re-triggered after an open-webui update.

Description

Bug Summary: Python libraries listed as requirements in tools are not re-added after updating open-webui

Reproduction Details

Steps to Reproduce:
Update the docker container with sudo docker run --rm --volume /var/run/docker.sock:/var/run/docker.sock containrrr/watchtower --run-once After updating, ask the LLM a query that will require it to use a tool. If a tool with a python import is called, it will fail even if the import is includes in the requirements. If I go and click edit and save in each toolkit in the web ui, it will work after that. This has happened twice directly after upgrading.

Logs and Screenshots
