Load issue

[azev77]

Previously the following worked to automatically load all models:

for (i, model) in enumerate(models())
    load(model.name, pkg=model.package_name, verbosity=0) 
end

Now I get an error message:

ERROR: The `load` function is no longer supported. Use the `@load` macro instead, as in `@load RandomForestRegressor pkg = DecisionTree`.

Then I try:

for (i, model) in enumerate(models())
    @load model.name pkg = model.package_name
end

ERROR: ArgumentError: There is no model named "model.name" in the registry. 
 Run `models()` to view all registered models.

What you want to do is use interpolation, as in

name = "PCA"
@load $name

But @load does not support this yet (JuliaAI/MLJModels.jl#368). However there is a workaround:

name = "PCA"
@eval @load $name

So the following works for me:

using Pkg
Pkg.activate(temp=true)
Pkg.add("MLJ")

using MLJ
model_types = []
for model in models()
    T = @eval @load $(model.name) pkg=$(model.package_name) add=true
    push!(model_types, T)
end
model_instances = map(T -> T(), model_types)
