Benjamin Glass e7ec05be9f [dynamo] Minimize get_backend overhead slightly further (#200300)
Reduce overhead of get_backend by switching from hasattr->getattr to PyObject_GetOptionalAttr.  The code is slightly more complicated, but shaves off warm-cache compile overhead.

Code co-written with Claude Opus 5.5

PyTorch Benchmarks

This folder contains scripts that produce reproducible timings of various PyTorch features.

It also provides mechanisms to compare PyTorch with other frameworks.

Setup environment

Make sure you're on a machine with CUDA, torchvision, and pytorch installed. Install in the following order:

# Install torchvision. It comes with the pytorch stable release binary
python -m pip install torch torchvision

# Install the latest pytorch master from source.
# It should supersede the installation from the release binary.
cd $PYTORCH_HOME
python -m pip install --no-build-isolation -v -e .

# Check the pytorch installation version
python -c "import torch; print(torch.__version__)"
