+## Common Issues & Fixes
+
+| Issue | Cause | Fix |
+|-------|-------|-----|
+| "File not found" | Wrong path | Check `data_path` and `output_dir` |
+| "Memory error" | Batch too large | Reduce `batch_size` |
+| "Split error" | Ratios > 1.0 | Ensure splits sum to ≤ 1.0 |
+| "Poor performance" | Wrong learning rate | Try 1e-5 to 5e-5 range |
+| "Slow processing" | Text too long | Reduce `max_length` |
