Saving and reading results

Saving results locally

Lighteval will automatically save results and evaluation details in the directory set with the --output-dir option. The results will be saved in {output_dir}/results/{model_name}/results_{timestamp}.json. Here is an example of a result file. The output path can be any fsspec compliant path (local, s3, hf hub, gdrive, ftp, etc).

To save the details of the evaluation, you can use the --save-details option. The details will be saved in a parquet file {output_dir}/details/{model_name}/{timestamp}/details_{task}_{timestamp}.parquet.

Pushing results to the HuggingFace hub

You can push the results and evaluation details to the HuggingFace hub. To do so, you need to set the --push-to-hub as well as the --results-org option. The results will be saved in a dataset with the name at {results_org}/{model_org}/{model_name}. To push the details, you need to set the --save-details option. The dataset created will be private by default, you can make it public by setting the --public-run option.

Pushing results to Tensorboard

You can push the results to Tensorboard by setting --push-to-tensorboard. This will create a Tensorboard dashboard in a HF org set with the --results-org option.

How to load and investigate details

Load from local detail files

from datasets import load_dataset
import os

output_dir = "evals_doc"
model_name = "HuggingFaceH4/zephyr-7b-beta"
timestamp = "latest"
task = "lighteval|gsm8k|0"

if timestamp == "latest":
    path = f"{output_dir}/details/{model_org}/{model_name}/*/"
    timestamps = glob.glob(path)
    timestamp = sorted(timestamps)[-1].split("/")[-2]
    print(f"Latest timestamp: {timestamp}")

details_path = f"{output_dir}/details/{model_name}/{timestamp}/details_{task}_{timestamp}.parquet"

# Load the details
details = load_dataset("parquet", data_files=details_path, split="train")

for detail in details:
    print(detail)

Load from the HuggingFace hub

from datasets import load_dataset

results_org = "SaylorTwift"
model_name = "HuggingFaceH4/zephyr-7b-beta"
sanitized_model_name = model_name.replace("/", "__")
task = "lighteval|gsm8k|0"
public_run = False

dataset_path = f"{results_org}/details_{sanitized_model_name}{'_private' if not public_run else ''}"
details = load_dataset(dataset_path, task.replace("|", "_"), split="latest")

for detail in details:
    print(detail)

The detail file contains the following columns:

choices: The choices presented to the model in the case of mutlichoice tasks.
gold: The gold answer.
gold_index: The index of the gold answer in the choices list.
cont_tokens: The continuation tokens.
example: The input in text form.
full_prompt: The full prompt, that will be inputed to the model.
input_tokens: The tokens of the full prompt.
instruction: The instruction given to the model.
metrics: The metrics computed for the example.
num_asked_few_shots: The number of few shots asked to the model.
num_effective_few_shots: The number of effective few shots.
padded: Whether the input was padded.
pred_logits: The logits of the model.
predictions: The predictions of the model.
specifics: The specifics of the task.
truncated: Whether the input was truncated.
