我有一个问题，我知道很多人听说过。我从装有GTX 1050 Ti的笔记本电脑升级到了配备RTX 3060 Ti的台式机。我在Anaconda虚拟环境中运行所有内容。我已经将我的env从笔记本电脑复制到了台式机上。现在，TensorFlow GPU需要很长时间才能启动。即使我只写这两行代码：
from tensorflow.python.client import device_lib
print(device_lib.list_local_devices())
这个过程需要很长时间（超过30分钟），但同样的操作在我的配备有GTX 1050 Ti的笔记本电脑上完美运行。我尝试了很多方法：
- 重新安装所有软件包到另一个环境中（当然，使用的是相同版本 - 我正在使用TF 2.1、cudnn 7.6.5、cudatoolkit 10.1.243）。
- 在程序之前添加了一些代码行（我尝试了10多种不同的可能性）。
- 清除GPU驱动并重新安装。
无论如何，如果有人找到了答案，请与我分享！提前致谢并祝你有愉快的一天！
