Hello everyone,

It is well known that observations on derivatives can be used to train GP. (e.g. [https://proceedings.neurips.cc/paper/2002/file/5b8e4fd39d9786228649a8a8bec4e008-Paper.pdf](https://proceedings.neurips.cc/paper/2002/file/5b8e4fd39d9786228649a8a8bec4e008-Paper.pdf)) I wonder whether there is any existing Julia package that can achieve that.

Thank you for your help!
