  2. Which extra state is typically needed for training resumption beyond model weights?
    • Nikan ik išedede Dimegilio
    • Optimizer and scheduler state, step progress, RNG state, and relevant data-loader progress
    • Only a model-weight shard index
    • A screenshot of the training dashboard
  3. Kini anfani akọkọ ti ikẹkọ atunbere fun awọn iṣẹ pipẹ?

    • Ijamba tabi iṣaju ko ni ipa lati tun bẹrẹ lati ibere
    • O ti jade ni optimizer
  4. In a sharded distributed checkpoint, how can ranks avoid gathering the entire state on one worker?
    • By saving their assigned local tensor shards with checkpoint metadata
    • By each emailing a full model copy
    • By deleting optimizer state before every save
    • By disabling all state serialization

  7. A package contains safetensors weight shards and an index, but no optimizer state. What can it support by itself?
    • Loading model weights, without fully restoring optimizer training history
    • Guaranteed exact resumption of every interrupted run
    • Recovering the next batch position automatically
    • Reconstructing every random-number-generator state
  8. A sharded checkpoint loader supports a new rank layout. What should the team verify before trusting recovery?
    • That fewer ranks guarantee identical floating-point results
    • That the weight index alone includes every application state
    • That no restart test is necessary
    • That the necessary saved state loads correctly and the resumed training step behaves as expected
