Я установил tensorflow-gpu на свой новый компьютер и систему, и все отлично распознает мой графический процессор, для этого я попробовал на своем терминале:
Тест Nvidia:
nvcc --version
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2019 NVIDIA Corporation
Built on Sun_Jul_28_19:07:16_PDT_2019
Cuda compilation tools, release 10.1, V10.1.243
Однако, пытаясь узнать, распознает ли tenorflow GPU, который я пробовал:
Тест Tensorflow:
import tensorflow as tf
tf.test.is_gpu_available()
Результат:

С другой стороны, следуя предложение дано здесь . Я пробовал следующие команды:
Другой тест Tensorflow:
from tensorflow.python.client import device_lib
device_lib.list_local_devices()
И получаю следующие журналы.

Tenorflow распознает мой графический процессор? Некоторые результаты говорят мне True, а другие - False. Пожалуйста, помогите.
Изменить
Другой тест, который я сделал:
import tensorflow as tf
tf.test.is_built_with_cuda()
True
Что здесь не так?
