【问题描述】:
当尝试运行一些 Pytorch 代码时,我收到此错误:
THCudaCheck FAIL file=/pytorch/aten/src/THC/THCGeneral.cpp line=74 error=38 : no CUDA-capable device is detected
Traceback (most recent call last):
File "demo.py", line 173, in test
pca = torch.FloatTensor( np.load('../basics/U_lrw1.npy')[:,:6]).cuda()
RuntimeError: cuda runtime error (38) : no CUDA-capable device is detected at /pytorch/aten/src/THC/THCGeneral.cpp:74
我使用“Google 深度学习虚拟机”运行云虚拟机 版本:tf-gpu.1-13.m25 基于:Debian GNU/Linux 9.9 (stretch) (GNU/Linux 4.9.0-9-amd64 x86_64\n) Linux tf-gpu-interruptible 4.9.0-9-amd64 #1 SMP Debian 4.9.168-1 (2019-04-12) x86_64

torch 错误消息:
no CUDA-capable device is detected告诉您当前用户没有权限从您闪亮的 nvidia GPU 读取或写入。默认情况下,视频卡或 GPU 通常归root所有。尝试使用sudo只运行一次程序,或者暂时以root 身份运行,如果解决了,那么您需要将video组添加到您的用户,例如:man useradd; useradd -a youruser video。
