我在 Ubuntu 22.04 上尝试运行 PyTorch 脚本并得到
torch.cuda.OutOfMemoryError: CUDA out of memory. Tried to allocate 86.00 MiB (GPU 0; 3.81 GiB total capacity; 3.18 GiB already allocated; 80.81 MiB free; 3.18 GiB reserved in total by PyTorch)
prime-select query得出以下结果：
on-demand
lspci | egrep 'VGA|3D'得出以下结果：
00:02.0 VGA compatible controller: Intel Corporation Alder Lake-P Integrated Graphics Controller (rev 0c)
01:00.0 3D controller: NVIDIA Corporation GA107M [GeForce RTX 3050 Ti Mobile] (rev a1)
nvidia-smi得出以下结果：

在我的 UbuntuAbout设置中，“Graphichs”显示为：
NVIDIA Corporation GA107M [GeForce RTX 3050 Ti Mobile] / Mesa Intel® Graphics (ADL GT2)
我怎样才能阻止我的 gpu 被用于Xorg和gnome-remote-desktop-daemon？我只想将我的 gpu 与 PyTorch 一起使用。使用torch.cuda.memory_allocated和torch.cuda.memory_reserved函数显示我正在使用0.0GB我的 gpu，尽管识别了 Nvidia gpu，所以我很困惑哈哈。
