Code problem in chapter 9 and probably in other chapter

[Vladasva]

Hi,

I bought your book. It is well written and interesting book. Thank you very much for a great work. However, I have found some problems in the code examples. By running chapter 9 notebook, i got an error here:

Any advice how to fix it?

Hi @Vladasva

I'm glad you enjoy the book and thank you for the message!

This error occurs, because you're likely using a non-matching version of one or more libraries (in this case seems like DoWhy is the cause)

Parts of the code in this and other chapters will not work correctly with DoWhy > 0.8

You can find consistent environments in the yml files in the repo, see here

At the current stage, for the best experience with the book, my recommendation would be to use the versions of libraries specified in the provided conda environments.

In the meantime, we're working on the updated code for the 2nd edition of the book, and on bringing back as much backwards compatibility to DoWhy in the future releases as possible.

I hope this helps,
Alex

You can fix this by replacing it with the following code:
effect_pred = estimate.estimator.effect(earnings_interaction_test.drop(['true_effect', 'took_a_course'], axis=1))
