AttributeError: module 'keras.optimizers' has no attribute 'adam_v2'

This error message indicates that the module 'keras.optimizers' does not have an attribute called 'adam_v2'. This could be due to a version mismatch between the Keras library and the TensorFlow backend. The 'adam_v2' optimizer was introduced in TensorFlow 2.0, so if you are using an older version of TensorFlow or Keras, this attribute may not be available.
To resolve this issue, you can try updating your TensorFlow and Keras versions to the latest ones. Alternatively, you can use a different optimizer that is available in your current version. For example, you can use 'Adam' optimizer instead of 'adam_v2'.
Here's an example of how to use the 'Adam' optimizer in Keras:
```
from keras.optimizers import Adam
model.compile(optimizer=Adam(lr=0.001), loss='binary_crossentropy')
```
