Implement MAPE metric?

[cdeterman]

I see that we can use MAE in the metrics of the river models in the examples and the API docs. However, I don’t see MAPE anywhere. Would there be a way to implement that metric that I am missing?

I just added it.

Wonderful, I assume I would need to install directly from GitHub to use it then?

Yep, you need to install the development version:

pip install git+https://github.com/online-ml/river --upgrade
