在 Ubuntu 18.04 服务器上安装 vulkun

我已经在 ubuntu 服务器上安装了 Vulkan，如下所示这。然而，当我跑步时，vulkaninfo我得到了

WARNING: [Loader Message] Code 0 : loader_icd_scan: Can not find 'ICD' object in ICD JSON file /usr/share/vulkan/icd.d/nvidia_layers.json.  Skipping ICD JSON
ERROR: [Loader Message] Code 0 : loader_scanned_icd_add: Could not get 'vkCreateInstance' via 'vk_icdGetInstanceProcAddr' for ICD libGLX_nvidia.so.0
ERROR: [Loader Message] Code 0 : vkCreateInstance: Found no drivers!
Cannot create Vulkan instance.
This problem is often caused by a faulty installation of the Vulkan driver or attempting to use a GPU that does not support Vulkan.

nvidia_layers.json不应该在 中/usr/share/vulkan/icd.d。该 JSON 文件描述的是层，而不是驱动程序。它属于/usr/share/vulkan/implicit_layer.d。但加载程序似乎正在寻找 ICD，因为它尝试从 加载函数地址libGLX.nvidia.so，即驱动程序。这看起来像是驱动程序安装不正确，或者有人移动了 JSON 文件。我会继续移动nvidia_layers.json到implicit_layer.d目录，看看是否有帮助，以防加载程序因该文件在 中而感到困惑icd.d。除此之外，请尝试重新安装驱动程序，并确保您拥有最新的 Vulkan 加载程序。最后，如果问题仍然存在，您可能会在 提交问题时获得更好的牵引力加载器 GitHub。
