about llama_factory SFT

[PioneerQyw]

nice work! I found that when you training at llama_factory with Simia-Tau-SFT-90k-Hermes, some data would be dropped.
Dropped invalid example: []
Is this normal?

Yes, that’s normal. Llama-Factory has strict format checks for agent trajectories, so a few samples that don’t fully match the schema will be dropped. It doesn’t affect training.
