因此，我尝试学习了几个教程（最新的是这个) 在 Ubuntu 20.04 上为 TensorFlow 设置 GPU 支持，我总是收到以下消息：
joris@joris-N751JK:~$ python3.9
Python 3.9.10 (main, Jan 15 2022, 18:17:56)
[GCC 9.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import tensorflow as tf
>>> tf.config.list_physical_devices('GPU')

[PhysicalDevice(name='/physical_device:GPU:0', device_type='GPU')]
这是什么意思以及如何解决？
