python - TensorFlow 只看到 cpu

Question

我已经尝试了几乎所有的方法，但 tensorflow 没有看到 gpu。

>>> tf.test.is_gpu_available()
WARNING:tensorflow:From <stdin>:1: is_gpu_available (from tensorflow.python.framework.test_util) is deprecated and will be removed in a future version.
Instructions for updating:
Use `tf.config.list_physical_devices('GPU')` instead.

Ubuntu 20.04

GPU-> geforce 940mx

CUDA-> 10.1

cudnn-> 7.6

张量流-GPU-> 2.3.1

我尝试重新安装 tensorflow、cuda、cudnn。详细的建议也无济于事（https://stackoverflow.com/a/55891075/13669210）
