For the time being you can manually add this with:

explainer = ClassifierExplainer(model, X, y)
explainer.shap_explainer = GPUTree(model, X)
ExplainerDashboard(explainer).run()

I will see however if I can add it add as option (although do not have a cuda device readily available for testing)

[oegedijk]

Made a PR here: #291

could you check if you can get this to work?

@oegedijk I do have a cuda device, for testing. I was thinking of sending a PR that shows OS and python compatibility.

cool, let me know if #291 works and can be merged or needs some modifications
