Description
Following the examples the SBD available backends is listed as
SBD Device Information
============================================================
✓ GPU Available: CUDA
GPU Count: 1
✓ CPU Available: Always
============================================================
but when running solve_sci I get:
RuntimeError: Backend 'cpu' not available. Available: []
indicating that I do not have any available backends

Research direction
Start at the solve_sci entry point and reproduce the reported mismatch between SBD Device Information and the runtime error. Trace how available backends are discovered and passed to solve_sci; done means the CPU backend is recognized and the example runs without Backend 'cpu' not available.
