testing tensorflow with gpu performance code example

Example 1: tensorflow gpu test

# As it's written in Tensorflow documentatoin: 

import tensorflow as tf
print("Num GPUs Available: ", len(tf.config.experimental.list_physical_devices('GPU')))

Example 2: tensorflow gpu test

  cuda_only=False, min_cuda_compute_capability=None
)
