'tensorflow' has no attribute 'config'

Question

I am trying to run the following line:

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

But it returns the error:

AttributeError: module 'tensorflow' has no attribute 'config'

Any ideas what I'm doing wrong?

Edit: Here's the initialization code

from __future__ import absolute_import, division, print_function, unicode_literals

import os
from glob import glob
import time
import tensorflow
#os.environ['KERAS_BACKEND'] = 'tensorflow'
#os.environ['TF_CPP_MIN_LOG_LEVEL'] = '3' # 3 = INFO, WARNING, and ERROR messages are not printed

I am using Tensorflow 2.0 as well. If anyone could help that would be great

Answer 1

For Tensorflow 2.x you should be using tf.test.gpu_device_name()

import tensorflow as tf
print("Num of GPUs available: ", len(tf.test.gpu_device_name()))
Num of GPUs available:  13

Answer 2

It could be because you have installed tensorflow 2.0 but the code was written for tensorflow 1.0

AttributeError: module 'tensorflow' has no attribute 'ConfigProto'

Please try this and see if it works.
