How to tell if tensorflow is using gpu acceleration from inside python shell?

You can check whether TensorFlow is using GPU acceleration from within a Python shell by examining the list of available devices and their characteristics using the tf.config.experimental.list_physical_devices() function. Here's how you can do it:

import tensorflow as tf # Get the list of available physical devices physical_devices = tf.config.experimental.list_physical_devices() # Check if any of the devices are GPUs gpu_devices = [device for device in physical_devices if device.device_type == 'GPU'] if gpu_devices: print("TensorFlow is using GPU acceleration.") for gpu in gpu_devices: print("GPU Device:", gpu) else: print("TensorFlow is NOT using GPU acceleration.")

Running this code will display whether TensorFlow is using GPU acceleration or not, along with the information about available GPU devices if any are detected.

Keep in mind that this code checks if GPUs are available and accessible by TensorFlow. However, it does not guarantee that TensorFlow will automatically use the GPU for all operations. TensorFlow will determine which operations should be placed on the GPU based on its own internal optimization and memory constraints. You can further control GPU usage using various TensorFlow configuration settings.
