AttributeError: 'Model' object has no attribute 'metrics_updates'

This error occurs when you try to access the `metrics_updates` attribute of a Keras `Model` object, but it does not exist.

The `metrics_updates` attribute was a feature in Keras 1.x that allowed users to define custom updates for metrics during training. However, it was removed in Keras 2.x as it was deemed unnecessary and could be accomplished through other means.

If you are using Keras 2.x and trying to access `metrics_updates`, you will need to find an alternative approach for achieving your desired behavior. You can try using the `callbacks` parameter in the `fit` method to define custom behavior during training.

AttributeError: 'Model' object has no attribute 'metrics_tensors'

This error occurs when you try to access an attribute called "metrics_tensors" on an object of the class "Model", but the attribute does not exist.

There are a few potential reasons why this may happen:

1. The "metrics_tensors" attribute may not be defined for the particular instance of the "Model" class that you are working with. Make sure that you have correctly initialized the model and that it has all the necessary attributes.

2. The "metrics_tensors" attribute may have been removed or renamed in a newer version of the library or framework you are using. Check the documentation for the version you are using to see if this is the case.

3. There may be a typo or other error in your code that is preventing the "metrics_tensors" attribute from being created or accessed correctly. Double-check your code for any mistakes or typos.

这个错误通常是由于使用了较旧版本的 Keras 或 TensorFlow 导致的。`metrics_tensors` 属性在新版本的 Keras 中已被移除。解决此问题的方法是更新 Keras 或 TensorFlow 到最新版本，或者修改代码以适应当前版本的 Keras。

如果你正在使用旧版本的 Keras，可以尝试以下解决方法：
- 检查并更新 Keras 和 TensorFlow 到最新版本：

  pip install --upgrade keras tensorflow

- 如果无法更新，可以尝试使用 `metrics` 属性替代 `metrics_tensors`：

  model.metrics

如果以上方法都无效，建议查看你的代码是否还有其他可能导致此问题的原因，并参考 Keras 官方文档或相关社区寻求帮助。
