CUDA Error

Hi, I got the following error :

Traceback (most recent call last): File "/render.py" rasterizer = GaussianRasterizer(raster_settings=raster_settings) File "/fast_gaussian_rasterization/fast_gauss/__init__.py", line 39, in __init__ raster_context = GSplatContextManager(init_buffer_size=init_buffer_size, init_texture_size=init_texture_size, dtype=dtype, tex_dtype=tex_dtype) # only created once File "/fast_gaussian_rasterization/fast_gauss/gsplat_utils.py", line 63, in __init__ self.resize_buffers(init_buffer_size) File "/fast_gaussian_rasterization/fast_gauss/gsplat_utils.py", line 247, in resize_buffers self.init_gl_buffers(self.max_verts) File "/fast_gaussian_rasterization/fast_gauss/gsplat_utils.py", line 184, in init_gl_buffers raise e File "/fast_gaussian_rasterization/fast_gauss/gsplat_utils.py", line 177, in init_gl_buffers self.cu_vbo = CHECK_CUDART_ERROR(cudart.cudaGraphicsGLRegisterBuffer(self.vbo, flags)) File "/fast_gaussian_rasterization/fast_gauss/cuda_utils.py", line 93, in CHECK_CUDART_ERROR raise RuntimeError(FORMAT_CUDART_ERROR(err)) RuntimeError: cudaErrorOperatingSystem(304): OS call failed or operation not supported on this OS

Environment Details:

• Driver Version: 550.54.15
• Docker Image: nvidia/cuda:11.6.2-devel-ubuntu20.04
• CUDA Toolkit: 11.6

Could you please provide information about the environment used ?

Hi, thanks for using our code.
The rasterizer is tested on native Windows and Ubuntu.
However, in my previous experience on other projects, the CUDA-GL interop should work fine on docker-based environments (at least for offline rendering). Thus this might be a usage issue. Could you provide more details, for example is your machine connected to a display, or are you using any Graphical forwarding (X11?) if this is a remote server?

I'm currently using offline rendering and the issue seems to occur at the beginning : raster_context = GSplatContextManager(init_buffer_size=init_buffer_size, init_texture_size=init_texture_size, dtype=dtype, tex_dtype=tex_dtype) line 39 of __init__.py file.

Could it be that some required packages are missing in my environment?
Do you have a list of packages used for offline rendering?

[dendenxu]

The required packages should have already been installed if you've run pip install -r requirements.txt without problems. In this situation, could you try running this test: https://github.com/zju3dv/EasyVolcap/blob/main/tests/headless_opengl_tests.py and check whether any error occurs? Note that since we're only testing the OpenGL environment, there's no need to install extra dependencies:

git clone https://github.com/zju3dv/EasyVolcap
cd EasyVolcap
pip install -e . --no-build-isolation --no-deps
python tests/headless_opengl_tests.py # maybe install missing packages if any fatal errors are reported
