gridfm-graphkit 0.0.7

Grid Foundation Model

gridfm-graphkit

This library is brought to you by the GridFM team to train, finetune and interact with a foundation model for the electric power grid.

---

Installation

Create and activate a virtual environment (make sure you use the right python version = 3.10, 3.11 or 3.12. I highly recommend 3.12)

python -m venv venv
source venv/bin/activate

Install gridfm-graphkit from PyPI

pip install gridfm-graphkit

torch-scatter is a required dependency. It cannot be bundled in pyproject.toml because the correct wheel depends on your PyTorch and CUDA versions, so it must be installed separately.

Get PyTorch + CUDA version for torch-scatter

TORCH_CUDA_VERSION=$(python -c "import torch; print(torch.__version__ + ('+cpu' if torch.version.cuda is None else ''))")

Install the correct torch-scatter wheel

pip install torch-scatter -f https://data.pyg.org/whl/torch-${TORCH_CUDA_VERSION}.html

For documentation generation and unit testing, install with the optional dev and test extras:

pip install "gridfm-graphkit[dev,test]"

Example with saved normalizer stats

When evaluating a model on a dataset, you can pass the normalizer statistics from the original training run to ensure the same normalization parameters are used:

gridfm_graphkit evaluate \
  --config examples/config/HGNS_PF_datakit_case118.yaml \
  --model_path mlruns/<experiment_id>/<run_id>/artifacts/model/best_model_state_dict.pt \
  --normalizer_stats mlruns/<experiment_id>/<run_id>/artifacts/stats/normalizer_stats.pt \
  --data_path data

Note: The --normalizer_stats flag only affects normalizers with fit_strategy = "fit_on_train" (e.g. HeteroDataMVANormalizer). Per-sample normalizers (HeteroDataPerSampleMVANormalizer) always recompute their statistics from the current dataset regardless of this flag.

Running Tests

Unit and Integration Tests

Install the test dependencies first (if not already done):

pip install -e .[dev,test]

Run the full unit test suite:

pytest ./tests

Run the base set integration tests:

pytest ./integrationtests/test_base_set.py

Running Base Set Tests on an LSF Cluster (GPU)

To submit the base set integration tests as an interactive LSF job with GPU access, use bsub. Adjust the paths to match your environment:

bsub -gpu "num=1" \
     -n 16 \
     -R "rusage[mem=32GB] span[hosts=1]" \
     -Is \
     -J gridfm_base_set_tests \
     /bin/bash -c "
       cd /path/to/gridfm-graphkit && \
       export PATH=/path/to/cuda/bin:\$PATH \
               CUDA_HOME=/path/to/cuda \
               LD_LIBRARY_PATH=/path/to/cuda/lib64:\$LD_LIBRARY_PATH && \
       source /path/to/venv/bin/activate && \
       pytest ./integrationtests/test_base_set.py
     "

Key bsub options used above:

Option	Description
-gpu "num=1"	Request 1 GPU
-n 16	Request 16 CPU slots
-R "rusage[mem=32GB] span[hosts=1]"	Reserve 32 GB of memory on a single host
-Is	Run as an interactive shell session
-J <job_name>	Assign a name to the job

Concrete example (adapt paths to your cluster setup):

bsub -gpu "num=1" -n 16 -R "rusage[mem=32GB] span[hosts=1]" -Is -J hpo_trial_190 /bin/bash -c "cd /dccstor/terratorch/users/rkie/gitco/gridfm-graphkit && export PATH=/opt/share/cuda-12.8.1/bin:\$PATH CUDA_HOME=/opt/share/cuda-12.8.1 LD_LIBRARY_PATH=/opt/share/cuda-12.8.1/lib64:\$LD_LIBRARY_PATH && source /u/rkie/venvs/venv_gridfm-graphkit/bin/activate && pytest ./integrationtests/test_base_set.py"
