如题,按照https://en.opensuse.org/SDB:NVIDIA_Bumblebee安装bumblebee后,运行
optirun glxgears --info
出现错误:
failed to create drawable
[VGL] ERROR: in OGLDrawable--
[VGL] 82: Could not create Pbuffer
但是optirun
可以运行程序。
安装bumblebee
的cuda9.0后运行了一个使用GPU的demo,提示无法找到cuda devices,报错如下:
THCudaCheck FAIL file=/opt/conda/conda-bld/pytorch_1535493744281/work/aten/src/THC/THCGeneral.cpp line=74 error=38 : no CUDA-capable device is detected

有木有坛子遇到这种情况的鸭…
