Hello. I can’t call expect\_column\_wasserstein\_distance\_to\_be\_less\_than. Why?

Because it is a great\_expectations\_experimental expectations and not a core one  
Note: `@Geri Leka` originally [posted this reply in Slack](https://greatexpectationstalk.slack.com/archives/CUTCNHN82/p1695651647258879?thread_ts=1695650342.086459&cid=CUTCNHN82). It might not have transferred perfectly.

Hi @nataly44 all experimental expectations are under `great_expectations/great_expectations/contrib/experimental/great_expectations_experimental/expectations`. This is including your **expect\_column\_wasserstein\_distance\_to\_be\_less\_than**

To utilize the experimental expectation, you can copy and paste this file to a specific location in your great expectations project folder (not the module folder) and import it. So for instance, you can put it in a folder called `expectations` right in the root of your project folder and do from **expectations.expect\_column\_wasserstein\_distance\_to\_be\_less\_than import …**
