我已经尝试挖矿一段时间了，但我的硬件似乎总是出现问题。我一直遵循以下挖矿部分的说明：

以下是有关 NVIDIA CUDA 工具包部分的说明：

经过多次尝试，我终于成功安装了 CUDA 驱动程序，并在我的设备查询中输出以下信息：
CUDA Device Query (Runtime API) version (CUDART static linking)

Device PCI Domain ID / Bus ID / location ID: 0 / 1 / 0
Compute Mode:
< Default (multiple host threads can use ::cudaSetDevice() with device simultaneously) >
deviceQuery, CUDA Driver = CUDART, CUDA Driver Version = 9.1, CUDA Runtime Version = 9.1, NumDevs = 1
Result = PASS
因为最后一行显示Result = PASS，我假设安装成功。这是我的nvidia-smi -a输出

尽管如此，当我运行时ethminer -M -G，我得到以下输出

Assuming 131072kB available aperture size.
May lead to reduced performance or incorrect rendering.

beignet-opencl-icd: no supported GPU found, this is probably the wrong opencl-icd package for this hardware
(If you have multiple ICDs installed and OpenCL works, you can ignore this message)
No GPU device with sufficient memory was found. Can't GPU mine. Remove the -G argument
似乎有不少人遇到过类似的问题，但我没有找到全面的解决方案。到目前为止，我找到了这个人：

谁被引导到一个解决方案，我无法完全理解：

通常不会问这个问题，但这个问题已经困扰我好几个星期了。任何帮助我都会很感激！提前谢谢，祝你好运！
