Shap: TreeExplainer's shap_values do not contains intercept value, it is not consistent with the doc's description
shap_model = shap.TreeExplainer(model)
shap_values = shap_model.shap_values(data)
shap_values.shape[1] is equal to data.shape[1]

Sorry the docs are updated on github but not yet on the pip version. In
your example use shap_model.expected_value
