I installed nvdiffrast using a docker image from dockerhub (https://hub.docker.com/r/rgabdullin/nvdiffrast_docker) and am trying to run the included sample (cube.py). When running the sample I get the error OSError: [Errno 30] Read-only file system despite specifying an output directory with the --outdir flag. Below is the error stack:

Solution: Figured that the cpp extensions used a disk which wasn't visible to my container. After making it visible the issue got resolved - closing the issue!
