[android][vulkan] Random output

Hello,
I am running the deploy_model_on_android.py example on android, with vulkan enabled. Despite some error messages (that should be ignored), I get an output, but it is not the one expected:

[15:58:15] /home/SERILOCAL/n.perto/Documents/tvm/src/runtime/vulkan/vulkan_device_api.cc:693: Cannot initialize vulkan: [15:58:15] /home/SERILOCAL/n.perto/Documents/tvm/src/runtime/vulkan/vulkan_device_api.cc:614: Check failed: __e == VK_SUCCESS: Vulan Error, code=-3: VK_ERROR_INITIALIZATION_FAILED

You can still compile vulkan module but cannot run locally
TVM prediction top-1: tench, Tinca tinca
Evaluate inference time cost...
Mean inference time (std dev): 693.35 ms (45.77 ms)

Most of the time I get tench but I sometimes have gotten something else. The expected result is cat.

I have the same result,who can explain this?
