Add progress bar to refutation operations since they take a long time to run

[amit-sharma]

Suggested by @sjgenco in #367

This would require

• usage of tqdm at the appropriate places in the loop for refutation functions.
• Adding tqdm as a requirement for DoWhy.

I'll start on this.

Okay, I've finished adding the progress bars to the refuters themselves. Now, I'm thinking about how to include options to silence them when not needed. I'm thinking to add a keyword argument to CausalRefuter.refute_estimate (like "disable_progress_bar" or smth). Then I probably also need to modify CausalModel.refute_estimate to have this argument also, so that users can silence the progress bars even if they aren't using the refuter object directly.

I will just do this if that works.

[amit-sharma]

yes, that sounds good @leo-ware In the spirit of avoiding double negatives, you may consider show_progress_bar={True/False} (True by default) instead of disable_progress_bar.

In addition, you can add any additional libraries used to the requirements.txt file.

I would be willing to work on this, we can add this to the estimator as well.

thanks, great to hear @yemaedahrav. If you have any questions as you start implementing it, you can ping on the #refutations channel on Discord.

I have implemented this with the show_progress_bar={True/False} option. I have made the commit here. Once the other pull request is closed, I will create another PR for this.

Any updates on this?

I guess my PR https://github.com/py-why/dowhy/pull/567 addressed this, this issue can be closed
