A huge mess at the moment. Binary wheels point to the wrong location (“Library” Python install). I don’t want to use Homebrew on this Mac so resorted to compile from source.
First set up a project directory:
mkdir pygtest
cd pygtest
Init with a Python version and Torch version:
uv init --python 3.12
uv add torch==2.7.0 torchvision torchaudio
Then make sure Command Line Tools are installed:
xcode-select --install
Set up build tools:
uv pip install cmake ninja
Export compile variables:
export CC=clang
export CXX=clang++
export CFLAGS="-Xclang -fopenmp -I/usr/local/include"
export CXXFLAGS="$CFLAGS"
export LDFLAGS="-L/usr/local/lib -lomp"
export CMAKE_OSX_ARCHITECTURES=$(uname -m)
export MACOSX_DEPLOYMENT_TARGET=$(sw_vers -productVersion | cut -d. -f1-2)
Compile the easy packages that have source wheels:
for pkg in torch_scatter torch_sparse torch_cluster torch_spline_conv
do uv pip install --no-build-isolation --no-binary $pkg $pkg; done
Download and extract the right openmp binary (will be placed in /usr/local/include):
curl -O https://mac.r-project.org/openmp/openmp-19.1.0-darwin20-Release.tar.gz
sudo tar fvxz openmp-19.1.0-darwin20-Release.tar.gz -C /
Compile pyg-lib;
export PYG_TAG=0.4.0
uv pip install --no-binary :all: --no-build-isolation "git+https://github.com/pyg-team/pyg-lib.git@$PYG_TAG"
Add torch_geometric:
uv add torch_geometric
And test:
uv run python - <<'PY'
import torch, torch_geometric, pyg_lib, torch_scatter
print("Torch :", torch.__version__)
print("PyG :", torch_geometric.__version__)
print("pyg_lib :", pyg_lib.__version__)
print("torch_scatter :", torch_scatter.__version__)
print("MPS available :", torch.backends.mps.is_available())
PY
Torch : 2.7.0
PyG : 2.6.1
pyg_lib : 0.4.0
torch_scatter : 2.1.2
MPS available : True
