我已经在 CUDA SDK 中执行了 deviceQuery 程序。文件中多处理器和内核的数量为 0，我确定这不是真的。可能是什么原因？

./deviceQuery Starting...

Make sure you update your nvidia drivers to the latest available and then reboot. If that doesn't fix it, please run the following commands and post the output:

uname -a
nvidia-smi -q
lspci
echo $LD_LIBRARY_PATH
ldd /path/to/deviceQuery
ldconfig -p
devicequery (with all output, not just the card in question)

确保这件事：

  • 卸载所有旧显卡驱动程序并安装最新的 NVIDIA 显卡驱动程序。
  • 卸载所有旧的 CUDA 工具包并安装最新的 CUDA 工具包。
