This is my code:

```julia
using Clustering 
#dist = Distances.Euclidean()
X1 = rand(10, 10)

#dm = Distances.pairwise(dist, X1, dims=2)
 ppresult=kmeans(X1,2)

```

But it has the following errors:  
ERROR: LoadError: UndefVarError: pairwise not defined  
Stacktrace:  
[1] \_kmeans!(X::Matrix{Float64}, weights::Nothing, centers::Matrix{Float64}, maxiter::Int64, tol::Float64, displevel::Int64, distance::SqEuclidean)

I don’t think this helps.  
You could instead edit the title of your original thread.
