Opengl backend on intel linux

综合讨论区
#1

Hi
I have a laptop with integrated intel graphics. I wonder if the opengl backend should be working with that?

My gpu is:

00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)

$ glxinfo | grep "direct rendering"
direct rendering: Yes

If i run the fractal example i get:

$ python3 fractal.py
[Taichi] version 1.0.1, llvm 10.0.0, commit 1c3619d9, linux, python 3.8.10
[W 05/12/22 17:46:55.317 322477] [cuda_driver.cpp:CUDADriver@38] CUDA driver not found.

[Taichi] Starting on arch=x64

Edit: started from a venv

I’m on kubuntu 20.04. The cpu rendering is working fine.
Thanks

Hi @rebootl , 目前Taichi 1.0.1版本对Intel某些型号的支持好像不太好。

你可以先试着跑一下Taichi 1.0.0么？

pip install taichi==1.0.0

如果还是出现问题，你可以先安装 Taichi 1.0.0, 然后用Vulkan backend来并行执行你的程序。

如果还是不行，请继续给我们留言。谢谢～
