ここからコードを使用しようとしています: https://github.com/pystruct/pystruct/blob/master/examples/multi_label.py
X_train には shape が(2591, 256)
あり、 y_train には shapeがあり(2591, 175)
ます。これを実行すると:
tree = chow_liu_tree(y_train)
tree_model = MultiLabelClf(edges=tree, inference_method="max-product")
tree_ssvm = OneSlackSSVM(tree_model, inference_cache=50, C=.1, tol=0.01)
print("fitting tree model...")
tree_ssvm.fit(X_train, y_train)
私はこれを得た:

リンクから直接コードを実行すると、(データセットで) 動作します。何が問題なのか知っている人はいますか?
