module 'tensorflow._api.v2.train' has no attribute 'AdamOptimizer'

The error message suggests that you are trying to access the `AdamOptimizer` class from the `tensorflow._api.v2.train` module, but this class is not defined in this module.
Starting from TensorFlow 2.0, the `tf.train` module has been deprecated and the optimizers are now available in the `tf.keras.optimizers` module. To use the `AdamOptimizer`, you can import it from `tf.keras.optimizers` as follows:
```python
from tensorflow.keras.optimizers import Adam
optimizer = Adam(lr=0.001)
```
This will create an instance of the `Adam` optimizer with a learning rate of 0.001. You can then pass this optimizer to your model's `compile` method to use it during training:
```python
model.compile(optimizer=optimizer, loss='mse')
```
This will compile the model with the `Adam` optimizer and the mean squared error loss function.
