我在 Windows 平台上安装 OpenEXR 时遇到问题。我用pip install OpenEXR

我正在尝试使用神经网络中的 sklearn 和 Tensorflow 包来实现 KFold 验证。

我的代码看起来像这样。

def training(self):
    n_split = 3
    instances = self.instance
    labels = self.labels
    for train_index, test_index in KFold(n_split).split(instances):
        x_train, x_test = instances[train_index], instances[test_index]
        y_train, y_test = labels[train_index], labels[test_index]
        model = self.mlp_model()
        model.fit(x_train, y_train, epochs=20)

        print('Model Evaluation', model.evaluate(x_test, y_test))

不幸的是，我收到一个错误
