Evaluation And Report Generation
This folder owns benchmark evaluation, shard merging, and report/summary generation.
It does not train models and does not build model checkpoints.
Main Files
eval_tokenizer_swap_benchmark.py
merge_tokenizer_swap_benchmark_shards.py
summarize_heldout_capabilities.py
run_public_heldout_eval_8gpu.sh
Input
The default benchmark is the latest public heldout 2K set kept in dataset_building/:
dataset_building/heldout_public_mcq_2k_20260607/heldout_public_mcq_2k.jsonl
The evaluation script expects a Hugging Face checkpoint directory as MODEL.
Run
ROOT=/ssd/yi/Tokenizer_Swap \
MODEL=/path/to/checkpoint \
LABEL=my_model \
bash evaluation_reporting/run_public_heldout_eval_8gpu.sh
The wrapper launches one shard per GPU, then merges shard outputs.
Output
Generated outputs go under:
evaluation_reporting/outputs/
This directory is ignored by git.
Each evaluation writes per-item JSONL plus summary JSON. The key reported metrics are:
- MCQ accuracy with average-normalized choice logprob
- MCQ accuracy with summed choice logprob
- perplexity
- NLL per token
- bits per byte
