Question about my Pkg

This is the modified program

After downloading Pkg again, there is no change

using LPVSpectral, Plots
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

It’s still reporting an error.

first you should make it easier to help you.
Its hard to get what the actual issue is:

How do you “download” the package:

  • ]pkg up ?
  • cd $PATH_TO_REPO ;git pull and then doing a ]dev "PATH_TO_REPO" in julia?
