Vulkan 1.4 support
Vulkan API version not supported. I'm on Vulkan 1.4.303 and the latest NVIDIA drivers 572.16.
To reproduce, run anything on any mode (cpu, gpu, cuda, vulkan)
[Taichi] version 1.7.3, llvm 15.0.1, commit 5ec301be, win, python 3.11.8
[Taichi] Starting on arch=cuda

@C4rb0n6 I added support to arm also and it is working https://github.com/taichi-dev/taichi/pull/8629
Reverting to NVIDIA drivers 566.36 with Vulkan 1.4.304 works for me (Taichi 1.7.3 + 1.6.0, Windows 10, 1080ti), I had the same issue before with 572.16.
I'm on Ubuntu 24.04, with NVidia driver 570.133 and Vulkan 1.4.303 on a Quadro T500 (a laptop NVidia GPU). I'm getting a similar assertion failure:
python: /home/dev/taichi/external/VulkanMemoryAllocator/include/vk_mem_alloc.h:16036: VkResult vmaCreateAllocator(const VmaAllocatorCreateInfo * _Nonnull, VmaAllocator * _Nonnull): Assertion `pCreateInfo->vulkanApiVersion == 0 || (((uint32_t)(pCreateInfo->vulkanApiVersion) >> 22) == 1 && (((uint32_t)(pCreateInfo->vulkanApiVersion) >> 12) & 0x3FFU) <= 3)' failed.
Fatal Python error: Aborted
If I understand correctly, my assertion failure happens when memory allocation is called. Would downgrading my Vulkan SDK fix this issue?
No you’d have to downgrade drivers. The latest taichi version’s vma doesn’t support 1.4
