Which version of MLJ are you on? You seem to roughly be running the intro example from the docs, which runs fine for me on MLJ version 0.6:

julia> using MLJ, RDatasets

julia> iris = dataset("datasets", "iris");

julia> y, X = unpack(iris, ==(:Species), colname -> true);

julia> tree_model = @load DecisionTreeClassifier verbosity = 1
import MLJModels ✔
import DecisionTree ✔
import MLJModels.DecisionTree_.DecisionTreeClassifier ✔
DecisionTreeClassifier(pruning_purity = 1.0,
                       max_depth = -1,
                       min_samples_leaf = 1,
                       min_samples_split = 2,
                       min_purity_increase = 0.0,
                       n_subfeatures = 0,
                       display_depth = 5,
                       post_prune = false,
                       merge_purity_threshold = 0.9,
                       pdf_smoothing = 0.05,) @ 1…93

julia> tree = machine(tree_model, X, y)
Machine{DecisionTreeClassifier} @ 4…03

Now its show this error on my data

Could you maybe post an MWE that reproduces your error as in the linked post? This would make it a lot more likely that someone on this forum can work out what’s going awry in your code.
