It would be great to have at least one simple example, like maybe the iris dataset one from the website's Getting Started section, that demonstrated how to load the data using NAlgebra.

Hi smartcore developers,

Thank you for such a nice tool. I am quite new to Rust, and have problem to run KNNClassifier with user defined parameters, say k value =5 instead of the default 3. I only saw KNNClassifier::fit(&x, &y, Default::default()).unwrap() with the default parameters, and got trouble when trying KNNClassifier::fit(&x, &y, KNNClassifierParameters { distance: Distances::euclidian(), algorithm: KNNAlgorithmName::CoverTree, weight: KNNWeightFunction::Uniform, k: 5, }).unwrap()
Could you help me figure out what was wrong here?

Dependabot couldn't fetch one or more of your project's path-based Rust dependencies. The affected dependencies were ../smartcore/Cargo.toml.

To use path-based dependencies with Dependabot the paths must be relative and resolve to a directory in this project's source code.
