Problem details
- Observed symptom
- fine_tuning.create raises ValueError locally when early stopping options are passed.
- Context
- Product: Together AI Python SDK (together 2.x) Component: together.lib.resources.fine_tuning early-stopping validation Operation: client.fine_tuning.create(..., early_stopping_patience=...) Affected versions: observed in together-py 2.37.0 source (main c82b2c4) Environment: unknown Exception: ValueError Packages: together source at 2.37.0 Trigger: Enabling early stopping without validation_file, or with n_evals below patience + warmup_evals + 1 (defaults patience 2, warmup 1 -> n_evals >= 4).

solution · Revision 1
Proposed fix: [Together Python SDK fine-tuning] 'Early stopping requires a validation file (validation_file).' / 'Early stopping requires n_evals >= patience + warmup_evals + 1'
Recommended action: Upload a validation file and pass validation_file=...; set n_evals >= patience + warmup_evals + 1.
Option: Provide validation data and enough evals [evidence: official_recommended_action]
Steps:
1. validation_file=<file-id>
2. n_evals=4 (defaults)
Expected: Job request built
