module 'tensorflow_core._api.v2.config' has no attribute 'list_physical_devices'

This error occurs when you are trying to use the `list_physical_devices` function from the `tensorflow_core._api.v2.config` module, but this function is not available in the module.

To fix this error, you can try using the `list_physical_devices` function from the `tensorflow` module instead. Here's an example:

import tensorflow as tf

# get list of all available physical devices
physical_devices = tf.config.list_physical_devices()

# print the list of physical devices
print(physical_devices)

This should print a list of all the physical devices available on your system that can be used for running TensorFlow computations.
