Hello! Which GPU do you have? Also can you try the Vulkan backend?

*Describe the bug*
With Taichi 0.8.1, ti.init(arch=ti.opengl) doesn't work.
Btw, ti.opengl with v0.7.32 and ti.cpu with v0.8.1 both work.
*To Reproduce*
A minimal Python file to reproduce:
import taichi as ti
ti.init(arch=ti.opengl)

My laptop only has an integrated GPU, Intel HD Graphics 630. I just tried the Julia set example with the Vulkan backend, and it worked. |

I think I have a rough idea why this might be happening, but in the
meantime maybe use the Vulkan backend, features wise Vulkan has multiple
Snode root and GL has a semi working global dynamic field, but I do suggest
using Vulkan backend if it works for you!

So I dug around the issue a bit, from the OpenGL specs: https://www.khronos.org/registry/OpenGL-Refpages/gl4/html/glClearBufferSubData.xhtml Which claims that there are only two ways this command generates error
However both of these are impossible according to the specs, as we did not call After double checking the code, I realized I used Hopefully that fix will be fixing this issue, as I have no Intel device to test & check against. I'm closing this for now, if this bug still exists after that fix is pushed into the next taichi release, please reopen it for me. |

Which commit fixes this issue? I still get this error with the following release: [Taichi] version 0.8.3, llvm 10.0.0, commit 021af5d, linux, python 3.9.7 [Taichi] Starting on arch=opengl

Hi, how do you get OpenGL without a GPU? |
|
Sorry, I am totally new to graphics programming. I was thinking GPU is not necessary for graphics programming. Please correct me if I am wrong. :) Maybe it would helpful to describe the hardware requirement to use Taichi? Thanks |
Hi! If you don't have a GPU you can call It's kind of interesting to see that the GL backend tried to initialize, we should probably address this. You don't need a GPU, just that some taichi examples are written to default to GPU and fallback to CPU. The fallback part failed. |
|
By the way, if you can provide some details on which cloud provider you used, what linux distro you used, and most preferably a rough idea of what is installed on the system, that would be very helpful for us to fix the fallback |
|
I just tried taichi v0.8.3 with integrated graphics (same setup as mentioned before: Ubuntu 20.04, Intel HD Graphics 630), and I still got the same issue. |
@Y7K4 does |
@k-ye For some reason when I use v0.8.0 I get a different error regardless of the backend. This looks like a different issue.
|

Ouch, that's actually sudo apt-get update
sudo apt-get install libz3-dev |

Thanks. We don't really have your card at hand ;-( Are you able to build Taichi from source (https://docs.taichi.graphics/lang/articles/contribution/dev_install)? If so, could you compare the outcome between
This would help us identify the problem a lot faster |

OK, I will try to build from source later this week. |
