@alexander-pv Hi Alexander, I believe this is related to the PR you submitted to SHAP. We are creating this issue so we can track the progress.
Do we have a workaround to run this before they merge the PR?

Hi, @vincewu51! For now, perhaps, the only way is to install this fork from source. I believe causalml support in shap will be added soon enough. I've just closed my debt there.

Ive installed the fork youve mentioned but am still getting
InvalidModelError: Model type not yet supported by TreeExplainer: <class 'causalml.inference.tree.causal.causaltree.CausalTreeRegressor'>

Anything i can do about it?

Hi @AlanGanem, the fork should be working. If not, SHAP package will merge the PR soon. You can track it here:Issue 3273

I have created an issue that similar to your problem => #735

Also I have found a way to plot shap values based on uplift_model.get_shap_values function but I am not clear how to define base_value that SHAP local plots requires. Any ideas ?

@alexander-pv, can you follow up on this with the SHAP team? Thanks.

Hi, all! Over the past few months, there have been over a hundred commits in shap project, so I updated shap/shap#3273 to speedup the process. The PR is expected to be in the next 0.46.0 shap release according to the milestone.
