Catboost-feature-importance - error in shap section

Hi, I was using the catboost feature importance notebook (from the feature-engineering-tutorial / feature-importance section) and I got an error:
AttributeError Traceback (most recent call last)
in
----> 1 explainer = shap.Explainer(model)
2 shap_values = explainer(X_test)
3 shap_importance = shap_values.abs.mean(0).values
4 sorted_idx = shap_importance.argsort()
5 fig = plt.figure(figsize=(12, 6))
AttributeError: module ‘shap’ has no attribute ‘Explainer’

Please check your version of the shap package. Explainer was added in version 0.36.0. If your version is earlier than this, you will need to upgrade.
