Hello @DManowitz! Thank you for the interest in hcrystalball

1. The project is currently not maintained. Our team shifted to work with another open source package, sktime, which is actively maintained.
2. We have encountered this issue, too, and resolved it with Update for new python, pandas, and sklearn versions #75. It did not pass the pipeline though, and we don't have enough resources to investigate it. You can use the wheel under git+https://github.com/heidelbergcement/hcrystalball.git@python-update, but we also can't guarantee that the branch will leave forever.
3. If you have interest in hcrystalball, you are free to fork it and maintain it under MIT license.

I leave the issue open so other people can find this information on top of the issues list.

@SmirnGregHM, if this project is not currently maintained, I think you should at least add this information to the top of the README so that it is obvious to anyone who looks at this repo. You might also want to archive the repo.
