我试图将我的GPU卡应用到TensorFlow笔记本电脑中，但我遇到了torch。
我有以下设置：

字符串
我可以运行这个代码：

# Create tensors on GPU
a = torch.tensor([1, 2, 3], device="cuda")
b = torch.tensor([4, 5, 6], device="cuda")

# Perform operations on GPU
c = a + b
print(c)

tensor([5, 7, 9], device='cuda:0')

的数据
但我无法运行下面的代码：

import tensorflow as tf

physical_devices = tf.config.list_physical_devices('GPU')
print("Num GPUs:", len(physical_devices))

型
我收到这个错误：

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
Cell In[12], line 1
----> 1 physical_devices = tf.config.list_physical_devices('GPU')
      2 print("Num GPUs:", len(physical_devices))

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

型
连这个也不行

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

--------------------------------------------------------------------------- AttributeError                            Traceback (most recent call
