I have a bug that is fatal error: EGL/egl.h: No such file or directory.

[BIG-PIE-MILK-COW]

I download nvdiffrast 0.3.0, and here are the errors.

On Linux, using the OpenGL-based rasterizer requires that you have both OpenGL and EGL installed. I suggest you take a look at our Dockerfile to see the required libraries and environment variables, or even better, use the Docker environment directly. Note that you will also need the OS-level graphics drivers installed in the system.

Since version v0.3.0 nvdiffrast includes a Cuda-based rasterizer that doesn't require the graphics libraries or drivers. It has some restrictions compared to OpenGL (see documentation) but it could be a working solution in your use case.

Sorry, I am confused. Can you directly tell how to solve this issue?

You have three options:

• Use our provided Dockerfile (what is Docker?)
• Set up your system so that it matches the configuration in the Dockerfile
• Use RasterizeCudaContext instead of RasterizeGLContext if you're ok with the limitations of the Cuda-based rasterizer
