Error running example

[DataExplorerUser]

Win 10, Python 3.8 running in a fresh venv with numpy and datoviz. Pip installed the windows wheels of v.0.1.0. Using PyCharm as IDE.

Running the following example code from the Datoviz website, resulted in an error.

import numpy as np
from datoviz import canvas, run, colormap

panel = canvas(show_fps=True).scene().panel()
visual = panel.visual('marker')

N = 10_000
pos = np.random.randn(N, 3)
ms = np.random.uniform(low=2, high=35, size=N)
color = colormap(np.random.rand(N), cmap='viridis')

visual.data('pos', pos)
visual.data('ms', ms)
visual.data('color', color)

run()

Error shown.

What is your GPU model and GPU driver version?
Can you determine if you have a libvulkan.dll file in your system files?

[DataExplorerUser]

I wouldn't know where to locate libvulkan.dll, so I searched the C drive with explorer. No items found. Also searched the Windows folder specifically with the same result. Any specific location I should check?

Using an HP Elitebook 840 laptop running Intel(R) Core(TM) i5-4300U CPU with on chip GPU.

Your hardware might not support Vulkan. If you install https://www.techpowerup.com/gpuz/, it might tell you whether you GPU chip supports Vulkan.

Just to bump this: my computer has a Intel UHD 620 card, which according to the link above, has Vulkan available. Moreover,
when installing the prebuilt wheel in a python virtualenv works fine, but when I try to build the library from source (Windows 11), I get the same error:

Traceback (most recent call last):

Additionally, when building on Windows, fyi you need to use python setup.py build_ext -i -c mingw --inplace -DMS_WIN64
