Dataset rows were audited with Qwen/Qwen3-8B chat-template tokenization.
Source max length: 1,316 tokens, p99: 1,300, so max_length=2048 is safe.
QLoRA NF4 + double quant follows the QLoRA recipe for fitting large models on one 48GB-class GPU.
LoRA uses target_modules="all-linear", recommended for QLoRA-style training.
assistant_only_loss=True trains only the JSON/config response tokens.
Evaluation is split by in-distribution and OOD splits; do not report only a single merged score.

Hardware target

Recommended server:

GPU: NVIDIA RTX 6000 Ada, 48GB/50GB VRAM
RAM: 64GB+
Disk: 200GB+ free
CUDA-compatible PyTorch

Default effective batch size:

text

per_device_train_batch_size = 2
gradient_accumulation_steps = 8
effective batch size = 16
max_length = 2048

If OOM occurs, preserve the effective batch size by changing:

yaml

per_device_train_batch_size: 1
gradient_accumulation_steps: 16

Do not reduce max_length unless you intentionally want a different training task.

Quick start with nohup, unique run dirs, and resumable checkpoints

bash

git clone https://huggingface.co/nraptisss/tmf921-intent-training
cd tmf921-intent-training

python -m venv .venv
source .venv/bin/activate
python -m pip install -U pip
bash scripts/install_rtx6000ada.sh
python scripts/check_gpu.py

export HF_TOKEN=hf_...
export CUDA_VISIBLE_DEVICES=0
export PYTHONPATH="$PWD/src"
export TOKENIZERS_PARALLELISM=false

bash scripts/nohup_new_run.sh

Monitor:

bash

RUN_DIR=runs/qwen3-8b-qlora-YYYYMMDD-HHMMSS
bash scripts/status_run.sh "$RUN_DIR"
tail -f "$RUN_DIR/logs/train.log"
watch -n 2 nvidia-smi

Resume:

bash scripts/nohup_resume.sh runs/qwen3-8b-qlora-YYYYMMDD-HHMMSS

Evaluate:

bash scripts/nohup_eval.sh runs/qwen3-8b-qlora-YYYYMMDD-HHMMSS

Configs

configs/rtx6000ada_qwen3_8b_qlora.yaml — recommended stage-1 config
configs/rtx6000ada_qwen3_14b_qlora_experimental.yaml — experimental 14B config
configs/stage2_weak_layer_qwen3_8b.yaml — diagnostic weak-layer continuation config

Evaluation

Raw evaluator:

bash

python scripts/evaluate_model.py \
  --model Qwen/Qwen3-8B \
  --adapter outputs/qwen3-8b-tmf921-qlora \
  --dataset nraptisss/TMF921-intent-to-config-research-sota \
  --output_dir outputs/qwen3-8b-tmf921-qlora/eval \
  --load_in_4bit

Normalize existing predictions:

bash

python scripts/normalize_eval_metrics.py \
  --eval_dir outputs/qwen3-8b-tmf921-qlora/eval

Metrics:

JSON parse rate
canonical JSON exact match
field precision / recall / F1
normalized field precision / recall / F1
normalized key precision / recall / F1
slice/SST diagnostic pass
KPI text-presence diagnostic pass
adversarial status pass
stratified metrics by target_layer, slice_type, and lifecycle_operation

Merge adapter for deployment/evaluation

bash

python scripts/merge_adapter.py \
  --base_model Qwen/Qwen3-8B \
  --adapter outputs/qwen3-8b-tmf921-qlora \
  --output_dir outputs/qwen3-8b-tmf921-merged

Stage 2 weak-layer continuation

Stage 2 was implemented and tested as a diagnostic experiment. It is not promoted as the main model because it did not materially improve O1/A1 and slightly regressed adversarial performance.

Run if needed:

bash scripts/nohup_stage2_weak.sh runs/qwen3-8b-qlora-YYYYMMDD-HHMMSS

Results packaging and qualitative failure analysis

After completing stage-1 and stage-2 evaluation plus normalization, package publication artifacts with:

bash

export PYTHONPATH="$PWD/src"

python scripts/package_results.py \
  --stage1_eval_dir runs/qwen3-8b-qlora-20260501-083834/eval_merged \
  --stage2_eval_dir runs/stage2-weak-20260505-080040/eval \
  --output_dir results

This writes:

text

results/stage1_raw_metrics.json
results/stage1_normalized_metrics.json
results/stage2_raw_metrics.json
results/stage2_normalized_metrics.json
results/metrics_summary.json
results/stage1_vs_stage2_comparison.md

Generate qualitative success/failure examples for the paper with:

bash

python scripts/sample_failure_examples.py \
  --eval_dir runs/qwen3-8b-qlora-20260501-083834/eval_merged \
  --output_dir analysis/stage1_examples

Optionally also sample stage-2 examples:

bash

python scripts/sample_failure_examples.py \
  --eval_dir runs/stage2-weak-20260505-080040/eval \
  --output_dir analysis/stage2_examples

The example sampler writes:

text

analysis/*/failure_examples.md
analysis/*/failure_examples.json

These artifacts are intended for paper tables, qualitative error analysis, and reproducibility appendices.

Scientific reporting protocol

For research papers/reports, report at least:

validation loss,
test_in_distribution metrics,
test_template_ood metrics,
test_use_case_ood metrics,
test_sector_ood metrics,
test_adversarial metrics,
per-target-layer field F1,
normalized field/key F1,
JSON parse rate,
rare-class metrics for lifecycle operations and adversarial categories.

Do not claim production standards compliance from JSON validity alone. Official TMF921/3GPP/ETSI/CAMARA/O-RAN validators are still needed for schema-level certification.

Usage

python

from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = 'nraptisss/tmf921-intent-training'
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id)

For non-causal architectures, replace AutoModelForCausalLM with the appropriate AutoModel class.
