VkPipeline array type incorrect (compute example fails)

[pieper]

(First - thanks for the cool package!).

Running the compute example fails with the trace below. I tried various fixes like ffi.new("VkPipeline*") etc but didn't find a way to fix it. I get the same behavior on linux and mac installations using either the pip package or installation from source.

It looks like this is related to #56.

$python example_mandelbrot_compute.py

Hello, Thanks for the report. Index I didn't updater the contrib tests. I will take a look.

Is there a version of the code in github or pypy that should work for the compute example?

You can try at this commit: https://github.com/realitix/vulkan/commit/6033845aa77d7d272e6d1be03f30b00fa1ac9c37

Yes, that one works - thanks!
