There was a problem hiding this comment.
Could you do this for OpenCL as well and I'll close #7672 ? I think this is better than returning nullptr

It seems we get segfault from Vulkan if a request to allocate 0 size is made. Returning nullptr in such case works for other backend, but VK seems to have issues. This workaround was confirmed to be effective.
Running NMS tests in
test_any.pyserves as the test case. Without this it would segfault.@tmoreau89 @mbrookhart @tqchen
