"""
Unified evaluator script: merges features from
- Mistral_sk_trained.py (local Mistral-SK base/SFT/DPO + local dataset-from-disk picker)
- LLM_test_m.py (generic model picker + HF datasets loader)
What you get in ONE file:
"""
Unified evaluator script.
Features:
- Interactive selection of:
* model source (Mistral-SK variants / predefined models / manual path)
* GPU (via CUDA_VISIBLE_DEVICES)
* dataset source (local load_from_disk / HuggingFace dataset)
* number of prompts, generation params
* number of prompts and generation parameters
- 4-bit loading (BitsAndBytes)
- Refusal detection + echo stripping
- Refusal detection + prompt-echo stripping
- Outputs: responses.txt, responses.json, summary.txt
