tensorflow gpu how many code example

Example 1: tensorflow check gpu

tf.config.list_physical_devices('GPU')

Example 2: gpu training tensorflow

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

Example 3: tensorflow gpu test

sess = tf.Session(config=tf.ConfigProto(log_device_placement=True))

Example 4: do i need do some set when i use GPU to train tensorflow model

from __future__ import absolute_import, division, print_function, unicode_literalsimport tensorflow as tfprint("Num GPUs Available: ", len(tf.config.experimental.list_physical_devices('GPU')))
