Running benchmarks using the Python API 🧪

You can run benchmarks from the Python API, using the Benchmark class and its launch method. It takes a BenchmarkConfig object as input, runs the benchmark in an isolated process and returns a BenchmarkReport object containing the benchmark results.

Here's an example of how to run an isolated benchmark using the pytorch backend, torchrun launcher and inference scenario with latency and memory tracking enabled.

from optimum_benchmark import Benchmark, BenchmarkConfig, TorchrunConfig, InferenceConfig, PyTorchConfig
from optimum_benchmark.logging_utils import setup_logging

setup_logging(level="INFO", handlers=["console"])

if __name__ == "__main__":
    launcher_config = TorchrunConfig(nproc_per_node=2)
    scenario_config = InferenceConfig(latency=True, memory=True)
    backend_config = PyTorchConfig(model="gpt2", device="cuda", device_ids="0,1", no_weights=True)
    benchmark_config = BenchmarkConfig(
        name="pytorch_gpt2",
        scenario=scenario_config,
        launcher=launcher_config,
        backend=backend_config,
    )
    benchmark_report = Benchmark.launch(benchmark_config)

    # log the benchmark in terminal
    benchmark_report.log() # or print(benchmark_report)

    # convert artifacts to a dictionary or dataframe
    benchmark_config.to_dict() # or benchmark_config.to_dataframe()

    # save artifacts to disk as json or csv files
    benchmark_report.save_csv("benchmark_report.csv") # or benchmark_report.save_json("benchmark_report.json")

    # push artifacts to the hub
    benchmark_config.push_to_hub("IlyasMoutawwakil/pytorch_gpt2") # or benchmark_config.push_to_hub("IlyasMoutawwakil/pytorch_gpt2")

    # or merge them into a single artifact
    benchmark = Benchmark(config=benchmark_config, report=benchmark_report)
    benchmark.save_json("benchmark.json") # or benchmark.save_csv("benchmark.csv")
    benchmark.push_to_hub("IlyasMoutawwakil/pytorch_gpt2")

    # load artifacts from the hub
    benchmark = Benchmark.from_hub("IlyasMoutawwakil/pytorch_gpt2") # or Benchmark.from_hub("IlyasMoutawwakil/pytorch_gpt2")

    # or load them from disk
    benchmark = Benchmark.load_json("benchmark.json") # or Benchmark.load_csv("benchmark_report.csv")

If you're on VSCode, you can hover over the configuration classes to see the available parameters and their descriptions. You can also see the available parameters in the Features section below.

Running benchmarks using the Hydra CLI 🧪

You can also run a benchmark using the command line by specifying the configuration directory and the configuration name. Both arguments are mandatory for hydra. --config-dir is the directory where the configuration files are stored and --config-name is the name of the configuration file without its .yaml extension.

optimum-benchmark --config-dir examples/ --config-name pytorch_bert

This will run the benchmark using the configuration in examples/pytorch_bert.yaml and store the results in runs/pytorch_bert.

The resulting files are :

benchmark_config.json which contains the configuration used for the benchmark, including the backend, launcher, scenario and the environment in which the benchmark was run.
benchmark_report.json which contains a full report of the benchmark's results, like latency measurements, memory usage, energy consumption, etc.
benchmark.json contains both the report and the configuration in a single file.
benchmark.log contains the logs of the benchmark run.

Advanced CLI options

Configuration overrides 🎛️

It's easy to override the default behavior of a benchmark from the command line of an already existing configuration file. For example, to run the same benchmark on a different device, you can use the following command:

optimum-benchmark --config-dir examples/ --config-name pytorch_bert backend.model=gpt2 backend.device=cuda

Configuration sweeps 🧹

You can easily run configuration sweeps using the --multirun option. By default, configurations will be executed serially but other kinds of executions are supported with hydra's launcher plugins (e.g. hydra/launcher=joblib).

optimum-benchmark --config-dir examples --config-name pytorch_bert -m backend.device=cpu,cuda

Configurations structure 📁

You can create custom and more complex configuration files following these examples. They are heavily commented to help you understand the structure of the configuration files.

Features 🎨

optimum-benchmark allows you to run benchmarks with minimal configuration. A benchmark is defined by three main components:

The launcher to use (e.g. process)
The scenario to follow (e.g. training)
The backend to run on (e.g. onnxruntime)

Launchers 🚀

Process launcher (launcher=process); Launches the benchmark in an isolated process.
Torchrun launcher (launcher=torchrun); Launches the benchmark in multiples processes using torch.distributed.
Inline launcher (launcher=inline), not recommended for benchmarking, only for debugging purposes.

General Launcher features 🧰

Assert GPU devices (NVIDIA & AMD) isolation (launcher.device_isolation=true). This feature makes sure no other processes are running on the targeted GPU devices other than the benchmark. Espepecially useful when running benchmarks on shared resources.

Scenarios 🏋

Training scenario (scenario=training) which benchmarks the model using the trainer class with a randomly generated dataset.
Inference scenario (scenario=inference) which benchmakrs the model's inference method (forward/call/generate) with randomly generated inputs.

Inference scenario features 🧰

Memory tracking (scenario.memory=true)
Energy and efficiency tracking (scenario.energy=true)
Latency and throughput tracking (scenario.latency=true)
Warm up runs before inference (scenario.warmup_runs=20)
Inputs shapes control (e.g. scenario.input_shapes.sequence_length=128)
Forward, Call and Generate kwargs (e.g. for an LLM scenario.generate_kwargs.max_new_tokens=100, for a diffusion model scenario.call_kwargs.num_images_per_prompt=4)

See InferenceConfig for more information.

Training scenario features 🧰

Memory tracking (scenario.memory=true)
Energy and efficiency tracking (scenario.energy=true)
Latency and throughput tracking (scenario.latency=true)
Warm up steps before training (scenario.warmup_steps=20)
Dataset shapes control (e.g. scenario.dataset_shapes.sequence_length=128)
Training arguments control (e.g. scenario.training_args.per_device_train_batch_size=4)

See TrainingConfig for more information.

Backends & Devices 📱

General backend features 🧰

Device selection (backend.device=cuda), can be cpu, cuda, mps, etc.
Device ids selection (backend.device_ids=0,1), can be a list of device ids to run the benchmark on multiple devices.
Model selection (backend.model=gpt2), can be a model id from the HuggingFace model hub or an absolute path to a model folder.
"No weights" feature, to benchmark models without downloading their weights, using randomly initialized weights (backend.no_weights=true)

Backend specific features 🧰

For more information on the features of each backend, you can check their respective configuration files:

Contributing 🤝

Contributions are welcome! And we're happy to help you get started. Feel free to open an issue or a pull request. Things that we'd like to see:

More backends (Tensorflow, TFLite, Jax, etc).
More tests (for optimizations and quantization schemes).
More hardware support (Habana Gaudi Processor (HPU), Apple M series, etc).
Task evaluators for the most common tasks (would be great for output regression).

To get started, you can check the CONTRIBUTING.md file.
