使用 python tvm 时,未检测到支持 CUDA 的设备
When using python tvm, No CUDA-capable device is detected
我写了下面的python代码
import tvm
ctx = tvm.device("cuda", 0)
print("ctx: ", ctx.exist)
输出为
ctx: False
但是,我安装了cuda和cuda驱动。
nvidia-smi
结果是,
NVIDIA-SMI 495.44 Driver Version: 495.44 CUDA Version: 11.5
我用lspci -vnn | grep VGA
检查是否有GPU。结果是
03:00.0 VGA compatible controller [0300]: Matrox Electronics Systems Ltd. Integrated Matrox G200eW3 Graphics Controller [102b:0536] (rev 04) (prog-if 00 [VGA controller])
3b:00.0 VGA compatible controller [0300]: NVIDIA Corporation Device [10de:1e04] (rev a1) (prog-if 00 [VGA controller])
af:00.0 VGA compatible controller [0300]: NVIDIA Corporation Device [10de:1e04] (rev a1) (prog-if 00 [VGA controller])
d8:00.0 VGA compatible controller [0300]: NVIDIA Corporation Device [10de:1e04] (rev a1) (prog-if 00 [VGA controller])
我的系统是Linux PowerEdge-R740 5.4.0-90-generic #101~18.04.1-Ubuntu
。我的python版本是3.6。
我不知道为什么 tvm 找不到正确的设备。
一个可能的错误来源可能是您在安装 TVM 时没有启用 CUDA 后端支持。
Edit build/config.cmake to customize the compilation options.
Change set(USE_CUDA OFF) to set(USE_CUDA ON) to enable CUDA backend. Do the same for other backends and libraries you want to build for (OpenCL, RCOM, METAL, VULKAN, …).

(我会评论的,但是声望不够)
