Chapter 3. Evaluating the model

Procedure

1. Navigate to your working Git branch where you created your qna.yaml file.

2. You can now run the evaluation process on different benchmarks. Each command needs the path to the trained samples model to evaluate, you can access these checkpoints in your ~/.local/share/instructlab/checkpoints folder.

   1. MMLU_BRANCH benchmark - If you want to measure how your knowledge contributions have impacted your model, run the mmlu_branch benchmark by executing the following command:

      $ ilab model evaluate --benchmark mmlu_branch
          --model ~/.local/share/instructlab/phased/phase2/checkpoints/hf_format/<checkpoint> \
          --tasks-dir ~/.local/share/instructlab/datasets/<node-dataset> \
          --base-model ~/.cache/instructlab/models/granite-7b-starter

      where

      <checkpoint>

      Specify the best scored checkpoint file generated during multi-phase training

      <node-dataset>

      Specify the node_datasets directory, in the ~/.local/share/instructlab/datasets/ directory, with the same timestamps as the.jsonl files used for training the model.

      Example output

      # KNOWLEDGE EVALUATION REPORT
      
      ## BASE MODEL (SCORE)
      /home/user/.cache/instructlab/models/instructlab/granite-7b-lab/ (0.74/1.0)
      
      ## MODEL (SCORE)
      /home/user/local/share/instructlab/phased/phases2/checkpoints/hf_format/samples_665(0.78/1.0)
      
      ### IMPROVEMENTS (0.0 to 1.0):
      1. tonsils: 0.74 -> 0.78 (+0.04)

   2. MT_BENCH_BRANCH benchmark - If you want to measure how your skills contributions have impacted your model, run the mt_bench_branch benchmark by executing the following command:

      $ ilab model evaluate \
          --benchmark mt_bench_branch \
          --model ~/.local/share/instructlab/phased/phase2/checkpoints/hf_format/<checkpoint> \
          --judge-model ~/.cache/instructlab/models/prometheus-8x7b-v2-0 \
          --branch <worker-branch> \
          --base-branch <worker-branch>

      where

      <checkpoint>

      Specify the best scored checkpoint file generated during multi-phase training.

      <worker-branch>

      Specify the branch you used when adding data to your taxonomy tree.

      <num-gpus>

      Specify the number of GPUs you want to use for evaluation.

3. Optional: You can manually evaluate each checkpoint using the MMLU and MT_BENCH benchmarks. You can evaluate any model against the standardized set of knowledge or skills, allowing you to compare the scores of your own model against other LLMs.

   1. MMLU - If you want to see the evaluation score of your new model against a standardized set of knowledge data, set the mmlu benchmark by running the following command:

      $ ilab model evaluate --benchmark mmlu --model ~/.local/share/instructlab/phased/phase2/checkpoints/hf_format/samples_665

      where

      <checkpoint>

      Specify one of the checkpoint files generated during multi-phase training.

      Example output

      # KNOWLEDGE EVALUATION REPORT
      
      ## MODEL (SCORE)
      /home/user/.local/share/instructlab/phased/phase2/checkpoints/hf_format/samples_665
      
      ### SCORES (0.0 to 1.0):
      mmlu_abstract_algebra - 0.31
      mmlu_anatomy - 0.46
      mmlu_astronomy - 0.52
      mmlu_business_ethics - 0.55

      mmlu_college_chemistry - 0.38
      mmlu_college_computer_science - 0.46
      ...

   2. MT_BENCH - If you want to see the evaluation score of your new model against a standardized set of skills, set the mt_bench benchmark by running the following command:

      $ ilab model evaluate --benchmark mt_bench --model ~/.local/share/instructlab/phased/phases2/checkpoints/hf_format/samples_665

      where

      <checkpoint>

      Specify one of the checkpoint files generated during multi-phase training.
