keras have no attribute __version__

Keras是一个深度学习框架，用于构建和训练神经网络模型。它是基于Python编程语言的开源库，提供了高级的API接口，使得构建深度学习模型变得更加简单和快速。

关于Keras没有`__version__`属性的问题，这可能是因为你使用的Keras版本较旧，或者你的安装存在问题。在较新的Keras版本中，`__version__`属性是存在的，并且可以用来获取Keras的版本号。

你可以通过以下代码来获取Keras的版本号：

import keras
print(keras.__version__)

如果你的Keras版本较旧，你可以尝试更新Keras到最新版本。你可以使用以下命令来更新Keras：

pip install --upgrade keras

请确保你的Python环境中已经安装了Keras，并且你的安装是正确的。如果你仍然遇到问题，请提供更多的错误信息，以便我能够更好地帮助你解决问题。

AttributeError: module 'keras.api._v2.keras' has no attribute 'metrics'

This error message is indicating that the module "keras.api._v2.keras" does not have an attribute called "metrics". This could be due to a few different reasons, such as:

1. The version of Keras you are using may not have the "metrics" module. Double-check your Keras version and see if it supports this module.
2. There may be a typo in your code where you are referring to "metrics" incorrectly. Make sure you are spelling it correctly and using the correct syntax.
3. There may be an issue with your Keras installation. Try reinstalling Keras and see if the issue persists.

module 'tensorflow.python.keras.api._v1.keras.layers' has no attribute 'batch_norm'

The error message suggests that there is no attribute called `batch_norm` in the `keras.layers` module of TensorFlow 1.x.

It is possible that you are using an outdated version of TensorFlow, or the attribute has been removed or renamed in a newer version.

In TensorFlow 1.x, the equivalent attribute is `BatchNormalization`. You can try importing it as follows:

from tensorflow.keras.layers import BatchNormalization

If you are using TensorFlow 2.x, the attribute is still `BatchNormalization`. However, the import statement would be:

from tensorflow.keras.layers import BatchNormalization

Make sure you have the correct version of TensorFlow installed and import the attribute using the correct syntax based on the version you are using.
