加载keras保存的模型时TypeError：（'关键字参数不理解：'，'模块'）

Question

我正在加载 keras 保存的模型并收到错误消息。

new_model=load_model("my_model.h5")
new_model.summary()

错误

我已经检查了我用来保存模型的 Keras 版本和我当前在计算机上的 Keras。两者相同，都是 Keras 2.2.4

当我尝试加载模型时

model= tf.keras.models.load_model(
"saved_models/",
custom_objects=None,
compile=True)

我收到以下权限被拒绝错误：

OSError: Unable to open file (unable to open file: name = 'saved_models/', errno = 13, error message = 'Permission denied', flags = 0, o_flags = 0)

我无法解决此问题，希望得到一些帮助

Answer 1

您没有使用 Keras 2.2.4 构建模型，您使用 tf.keras 构建它，现在您使用 keras 加载它。这两个模块实际上并不兼容，这就是您收到错误的原因。

简单的解决方案是永远不要将keras 与tf.keras 混合使用。
