Error in opengl

[lixiangweiabc]

Hi, I want to run this project on a cloud server through mobaxterm.
When I run the cmd evc -t gui -c configs/projects/realtime4dv/rendering/4k4d_actor5_6.yaml,configs/specs/video.yaml,get a error in function def common_opengl_options().
Could you please give me me some advice about the error. Hope your reply.

Hi, @lixiangweiabc!

Looks like there are several issues to address:

1. You've installed pyopengl==3.1.0. If this is the modified version from EasyMocap's guide, it might not be compatible with easyvolcap. Maybe try updating it with pip install -U pyopengl. The latest version should be 3.1.7
2. You mentioned that this is run through an X-server using a cloud server and it looks like you've already successfully created the opengl context. The options ALPHA_TEST and POINT_SPRITE were not available in recent opengl version so you could just try commenting them out in the code and see if we can successfully render. This could be due to the fact that we're running through a remote X-server. I added a window hint to use the compatibility profile during window initialization, but it might have been ignored.
3. It's recommended to run EasyVolcap's viewer locally. Running through X-server might hit the performance pretty hard.

Moreover, could you please also test if you can run off-screen rendering by replacing -t gui with -t test?

Hi,thank you for your address.I had tried the cmd evc -t test -c configs/projects/realtime4dv/rendering/4k4d_actor5_6.yaml,configs/specs/video.yaml by replacing -t gui with -t test. I got the next error:

RuntimeError: The NVIDIA driver on your system is too old (found version 11040). Please update your GPU driver by downloading and installing a new version from the URL: http://www.nvidia.com/Download/index.aspx Alternatively, go to: https://pytorch.org to install a PyTorch version that has been compiled with your version of the CUDA driver.

My nvidia driver version is :470.161.03, but my cuda version is:11.8. That might be incompatible. I will try a new machine with compatible nvidia driver and cuda. Could you please recommend a suitable Nvidia driver and cuda version on an ubuntu 18.04 machine.

Indeed, looks like cuda 11.8 is not supported for the 470.161.03 driver. We usually run with 525.125.06 and CUDA 11.8.
