python - 在训练 creme 随机森林分类器时获取“多项”对象没有属性“键”

Question

我正在使用 creme python 库和 RandomForestClassifier 模型并收到此错误：

AttributeError: 'Multinomial' object has no attribute 'keys'

谁能帮忙？

我的代码：

    from creme import stream
    from creme.metrics import Accuracy
    from creme.tree import RandomForestClassifier

    dataset = stream.iter_csv('data/data2.csv', target='HasDetections')

    model = RandomForestClassifier()
    metric = Accuracy()

    for (i, (x, y)) in enumerate(dataset):
        preds = model.predict_one(x)
        model = model.fit_one(x, y)
        metric = metric.update(y, preds)
        print("INFO] update {} - {}".format(i, metric))

    print("[INFO] final - {}".format(metric))
