------------------------------------
commit 301902be4f1332799cf3b3242cd29b4907c21c09
Author: Qian Zhang
Date: Sat Oct 10 15:04:57 2020 +0800
Ignored the directoy `/dev/nvidia-caps` when globing Nvidia GPU devices.
The directory `/dev/nvidia-caps` was introduced in CUDA 11.0, just
ignore it since we only care about the Nvidia GPU device files.
