Error in download golearn with 'go get ...' (go1.8.4)

$ go get github.com/sjwhitworth/golearn@latest                       
go: github.com/sjwhitworth/golearn@v0.0.0-20211014193759-a8b69c276cd8 requires
        github.com/rocketlaunchr/dataframe-go@v0.0.0-20201007021539-67b046771f0b requires
        github.com/blend/go-sdk@v1.1.1: reading github.com/blend/go-sdk/go.mod at revision v1.1.1: unknown revision v1.1.1

Maybe the vision1.1.1 of go-sdk is too old to use. I don't know how to download now!

See the bug report at dataframe-go;

add this to your go.mod

replace (
	github.com/blend/go-sdk v1.1.1 => github.com/blend/go-sdk legacy-v1.1.1
)

however, there is a new error now that

go: github.com/sjwhitworth/golearn@v0.0.0-20211014193759-a8b69c276cd8 requires
	github.com/rocketlaunchr/dataframe-go@v0.0.0-20201007021539-67b046771f0b requires
	github.com/cnkei/gospline@v0.0.0-20191204072713-842a72f86331: invalid version: unknown revision 842a72f86331

needing a replace directive involving some research

github.com/cnkei/gospline v0.0.0-20191204072713-842a72f86331 => github.com/cnkei/gospline v0.0.0-20191204052713-d67fac29a294

it seems rocketlaunchr/dataframe-go is a bit unmaintained; could rocketlaunchr/dataframe-go be removed as a dependency from golearn?

i will use this command to get this project.

cd ~/go/src
mkdir -p github.com/sjwhitworth
git clone https://github.com/sjwhitworth/golearn.git

update repo vendor

go mod tidy
go mod vendor

to use examples

cd examples/knnclassifier
go build knnclassifier_iris.go
./knnclassifier_iris
