Small helper to get the global step.

# Create a variable to hold the global_step.
global_step_tensor = tf.Variable(10, trainable=False, name='global_step')
# Create a session.
sess = tf.compat.v1.Session()
# Initialize the variable
# Get the variable value.
print('global_step: %s' % tf.compat.v1.train.global_step(sess,

global_step: 10

sess A TensorFlow Session object.
global_step_tensor Tensor or the name of the operation that contains the global step.
