This is the modified program
After downloading Pkg again, there is no change
using LPVSpectral, Plots
a=convert(Vector{Float64},rand(20))
λ = 0.02 # Regularization parameter
λs = 1 # Regularization parameter group-lasso
normal = true # Use normalized basis functions
Nv = 50 # Number of basis functions
x = sort(10rand(20))
v = range(0, stop=1, length=20)
se = ls_spectral_lpv(a,X,V,w_test,Nv; λ = λ, normalize = normal)
ERROR: LoadError: UndefVarError: warn not defined
