NVIDIA Eval Factory

The goal of NVIDIA Eval Factory is to advance and refine state-of-the-art methodologies for model evaluation, and deliver them as modular evaluation packages (evaluation containers and pip wheels) that teams can use as standardized building blocks.

Quick start guide

NVIDIA Eval Factory provide you with evaluation clients, that are specifically built to evaluate model endpoints using our Standard API.

Launching an evaluation for an LLM

1. Install the package

   pip install aa-lcr --index-url https://gitlab-master.nvidia.com/api/v4/projects/153108/packages/pypi/simple
   

2. (Optional) Set a token to your API endpoint if it's protected

   export MY_API_KEY="your_api_key_here"
   

3. List the available evaluations:

   $ eval-factory ls
   AA-LCR: 
     * aa_lcr
   

4. Run the evaluation of your choice:

   eval-factory run_eval \
       --eval_type aa_lcr \
       --model_id meta/llama-3.1-70b-instruct \
       --model_url https://integrate.api.nvidia.com/v1/chat/completions \
       --model_type chat \
       --api_key_name MY_API_KEY \
       --output_dir /workspace/results
   

5. Gather the results

   cat /workspace/results/results.yml
   

Command-Line Tool

Each package comes pre-installed with a set of command-line tools, designed to simplify the execution of evaluation tasks. Below are the available commands and their usage for the aa_lcr:

Commands

1. List Evaluation Types

eval-factory ls

Displays the evaluation types available within the harness.

2. Run an evaluation

The eval-factory run_eval command executes the evaluation process. Below are the flags and their descriptions:

Required flags

• --eval_type <string> The type of evaluation to perform
• --model_id <string> The name or identifier of the model to evaluate.
• --model_url <url> The API endpoint where the model is accessible.
• --model_type <string> The type of the model to evaluate, currently either "chat" or "completions".
• --output_dir <directory> The directory to use as the working directory for the evaluation. The results, including the results.yml output file, will be saved here.

Optional flags

• --api_key_name <string> The name of the environment variable that stores the Bearer token for the API, if authentication is required.
• --run_config <path> Specifies the path to a YAML file containing the evaluation definition.

Example

eval-factory run_eval \
    --eval_type aa_lcr \
    --model_id my_model \
    --model_type chat \
    --model_url http://localhost:8000 \
    --output_dir ./evaluation_results

If the model API requires authentication, set the API key in an environment variable and reference it using the --api_key_name flag:

export MY_API_KEY="your_api_key_here"

eval-factory run_eval \
    --eval_type aa_lcr \
    --model_id my_model \
    --model_type chat \
    --model_url http://localhost:8000 \
    --api_key_name MY_API_KEY \
    --output_dir ./evaluation_results

Configuring evaluations via YAML

Evaluations in NVIDIA Eval Factory are configured using YAML files that define the parameters and settings required for the evaluation process. These configuration files follow a standard API which ensures consistency across evaluations.

Example of a YAML config:

config:
  type: aa_lcr
  params:
    parallelism: 50
    limit_samples: 20
target:
  api_endpoint:
    model_id: meta/llama-3.1-8b-instruct
    type: chat
    url: https://integrate.api.nvidia.com/v1/chat/completions
    api_key_name: NVIDIA_API_KEY

The priority of overrides is as follows:

1. command line arguments
2. user config (as seen above)
3. task defaults (defined per task type)
4. framework defaults

--dry_run option allows you to print the final run configuration and command without executing the evaluation.

Example:

eval-factory run_eval \
    --eval_type aa_lcr \
    --model_id my_model \
    --model_type chat \
    --model_url http://localhost:8000 \
    --output_dir .evaluation_results \
    --dry_run

Output:

Deploying a model as an endpoint

NVIDIA Eval Factory utilize a client-server communication architecture to interact with the model. As a prerequisite, the model must be deployed as an endpoint with a NIM-compatible API.

Users have the flexibility to deploy their model using their own infrastructure and tooling.

Servers with APIs that conform to the OpenAI/NIM API standard are expected to work seamlessly out of the box.
