I'm not really sure what does it means, can you post the full error message please?

From the error I would suggest try two things:

1. Update ninja in your conda environment: pip install --upgrade ninja or pip install --upgrade -r requirements.txt
2. set force_cuda_rasterize=True in the node

2. set force_cuda_rasterize=True in the node

Following the method of operation, the error still exists

ImportError: DLL load failed while importing nvdiffrast_plugin: the specified module cannot be found.

I was able to get past that error by installing Ninja in Windows, I use Winget (built into windows 11) Open Command Prompt / Terminal winget install ninja-build.ninja Now from my miniconda activated command prompt if I type Ninja --version it returns 1.11.1 and I'm able to run the workflow.

I'm sure you could download and install for the other OS - https://github.com/ninja-build/ninja/wiki/Pre-built-Ninja-packages

Hopefully that helps someone :)
