 - As of 9/22/20, the interactive pipeline runs on TFX version 0.24.0rc1.
 Due to tiny TFX bugs, the pipelines currently don't work on the releases 0.23 and 0.24-rc0. Github issues have been filed with the TFX team specifically for the book pipelines ([Issue 2500](https://github.com/tensorflow/tfx/issues/2500#issuecomment-695363847)). We will update the repository once the issue is resolved.
