📄 Description

Problem

When a model requires a newer version of Ollama, users see cryptic error messages that are hard to recognize. Issue #3395 requested a clearer error message.

Solution

This PR adds a version check in the scheduler before loading a model. If the current Ollama version is older than what the model requires, a clear error message is displayed:

a new version of Ollama is required to run this model (minimum version: X.Y.Z, current version: A.B.C)

The fix:

  1. Checks req.model.Config.Requires against version.Version using semantic versioning
  2. Uses golang.org/x/mod/semver for proper version comparison
  3. Returns early with a descriptive error message if the version check fails

Changes

  • server/sched.go: Added version check logic in the load() function
    • Added imports for version and semver packages
    • Added version comparison before model loading

Testing

The Go syntax has been verified using gofmt. Full build and test should be run in CI.
