go\pkg\mod\github.com\sjwhitworth\[email protected]\knn\knn.go:132:16: KNN.optimisedEuclideanPredict undefined (type *KNNClassifier has no field or method optimisedEuclideanPredict)

looking around I found this issue about the need of CGO

If you want to install it like this, you need a c compiler on your system. I think then your issue should be solved. I'll make this more clear in the readme, thanks for pointing this out. Alternatively, you can install goskyr in a different way, eg by downloading the correct binary from the releases page, see https://github.com/jakopako/goskyr/releases
