evals

This is a script to simplify running many evals simultaneously in our slurm environment. It accepts hugging face model IDs (i.e. org/modelname) or directory paths to models in the huggingface format.

Usage

Common run configs can be found in command line scripts like cpt.sh which you can run like

# run common tests for finnish CPT evals
sh cpt.sh /path/to/somemodel

You can also invoke the script directly to run individual evals as needed.

python main.py \
    --partition standard-g
    --time 04:00:00
    --model path/to/model_step1234 \
    eval_name1 eval_name2

The script will try to avoid running nevals for which you already have results or for which there already appear to be jobs in the slurm queue. It determines this latter case by reviewing the logs in command_history.jsonl.

Slurm job output is stored in the logs subdir.

Results

Output is written by default into the output subdirectory. The results are stored in json format which is not particularly convenient. There is a summary.sh script which will extract the correct scores each eval that is available.

sh summary.sh output/v2/meta-llama/Llama-3.1-8B

Watching job status.

The watch.py script is a convenience script to help keep track of the jobs you have running, it has two operational modes.

In the default mode it prints the jobs that are currently in the queue or running, and if available it prints the last line in the error log in each file, which often contains the most recent tqdm progress bar for jobs that are running. If you specify the --once flag it will do this and exit, if you do not specify the --once flag it will keep checking job status periodically and provide updates as jobs complete.

$ python watch.py --once

There is another new operational mode recently added that might be more useful. Specifying the --hist flag will show a report of the jobs that have completed in the last 3 days (controllable with the --days flag) sorted by model name and status. It also does some coalescing: if an eval is ultimately successful, it won't bother reporting on failed runs, etc. This is helpful to identify evals which have failed and need to be investigated or rerun.

$ python watch.py --hist --days 1

Command History

All evals are logged in command_history.jsonl, which is used by various scripts to monitor job status and report history.

An entry looks like this.

{
    "timestamp": "2023-11-09 08:21:12",
    "script_name": "/tmp/tmpvv66ri7g",
    "job_id": "4868114",
    "eval": "hellaswag",
    "model": "/scratch/project_462000319/general-tools/checkpoints/33B_torch_step70128_bfloat16",
    "tokenizer": "/scratch/project_462000319/tokenizers/tokenizer_v6_fixed_fin",
    "err_log": "/pfs/lustrep4/scratch/project_462000319/evals/logs/4868114.err",
    "out_log": "/pfs/lustrep4/scratch/project_462000319/evals/logs/4868114.out",
    "output_file": "/pfs/lustrep4/scratch/project_462000319/evals/output/poro-34b/step70128/hellaswag.json"
}

You can utilize the information directly as well. If you've just queued up a bunch of evals against a model and realized you made a mistake and need to cancel them all, you could do something like this to save a lot of typing:

grep /path/to/model command_history.jsonl | jq -r .job_id | xargs scancel
