All benchmarks are wrong, some will cost you less than others.

Optimum-Benchmark is a unified multi-backend & multi-device utility for benchmarking Transformers, Diffusers, PEFT, TIMM and Optimum libraries, along with all their supported optimizations & quantization schemes, for inference & training, in distributed & non-distributed settings, in the most correct, efficient and scalable way possible.

Motivations 🎯

• HuggingFace hardware partners wanting to know how their hardware performs compared to another hardware on the same models.
• HuggingFace ecosystem users wanting to know how their chosen model performs in terms of latency, throughput, memory usage, energy consumption, etc compared to another model.
• Benchmarking hardware & backend specific optimizations & quantization schemes that can be applied to models and improve their computational/memory/energy efficiency.

Optimum-Benchmark is continuously and intensively tested on a variety of devices, backends, scenarios and launchers to ensure its stability with over 300 tests running on every PR (you can request more tests if you want to).

You can install the latest released version of optimum-benchmark on PyPI:

pip install optimum-benchmark

or you can install the latest version from the main branch on GitHub:

pip install git+https://github.com/huggingface/optimum-benchmark.git

or if you want to tinker with the code, you can clone the repository and install it in editable mode:

git clone https://github.com/huggingface/optimum-benchmark.git
cd optimum-benchmark
pip install -e .

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.

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.

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

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

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)

• 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.

• 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.

• Pytorch backend for CPU (backend=pytorch, backend.device=cpu)
• Pytorch backend for CUDA (backend=pytorch, backend.device=cuda, backend.device_ids=0,1)
• Pytorch backend for Habana Gaudi Processor (backend=pytorch, backend.device=hpu, backend.device_ids=0,1)

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.
