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It is possible that you are using an outdated version of TensorFlow, or the attribute has been removed or renamed in a newer version.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