[MoE] Incompatible model version: ${model.version}

Error message

[MoE] Incompatible model version: ${model.version}

What it means

Log warning in loadWeights: the persisted MoE weights file's version is missing or not 1.x, so the file is incompatible with this code; load returns false and the router keeps its initialized default weights.

Solutions

1. Delete or migrate the persisted MoE model to the current version; a fresh model is created when versions mismatch.
