Bug Report

Description

Bug Summary:

If you're building Ollama yourself, by default it doesn't generate a version the same as the release versions, it either generates its version as 0.0.0, as the SHA of the branch/tag you're on (e.g. a2d24d5) or a pre-release RC version (e.g. v0.1.33-RC5).

This seems to cause Open WebUI to experience a crash when checking the Ollama server.

For example, my Ollama build is:

$ curl https://ollama.internal/api/version
{"version":"v0.1.33-rc5"}

Which causes an error in Open WebUI when checking the server:

Logs:

...
  File "/app/backend/apps/ollama/main.py", line 219, in <lambda>
    key=lambda x: tuple(map(int, x["version"].split("-")[0].split("."))),
                  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
ValueError: invalid literal for int() with base 10: 'v0'

Steps to Reproduce:

Expected Behaviour:

  • Open WebUI to function normally regardless of being on a build with version v1.2.3/v1.2.4-rc5/, (perhaps show a warning in the connection settings if it's an unknown version).

Actual Behaviour:

  • "Server connection failed" in the UI.... but it actually works
  • Errors in the container logs about the version

Environment

  • Open WebUI Version: v0.1.121

  • Ollama (if applicable): v0.1.33-rc5

  • Operating System: Linux/Container

  • Browser (if applicable): Firefox 125

Reproduction Details

Confirmation:

  • I have read and followed all the instructions provided in the README.md.
  • I am on the latest version of both Open WebUI and Ollama.
  • I have included the browser console logs.
  • I have included the Docker container logs.
