Frequently Asked Questions

How should I cite GraphVite?

If you find GraphVite helps your research, please cite it in your publications.

    title={GraphVite: A High-Performance CPU-GPU Hybrid System for Node Embedding},
    author={Zhu, Zhaocheng and Xu, Shizhen and Qu, Meng and Tang, Jian},
    booktitle={The World Wide Web Conference},

Why is there a PackagesNotFoundError in conda installation?

Some dependencies of the library aren’t present in the default channels of conda. Config your conda with the following command, and try installation again.

conda config --add channels conda-forge

Why is there a compilation error for template deduction?

This is due to a failure of old version nvcc in compiling the templates in pybind11. Generally, nvcc 9.2 or later will work.

Why is the access to embeddings so slow?

Due to the binding mechanism, the numpy view of embeddings is generated each time when you access the embeddings in Python. Such generation may take a non-trivial overhead. To avoid that cost, we recommend you to copy the reference of the embeddings.

embeddings = solver.vertex_embeddings

Now the access to embeddings should be good.
