[Question] --writable issues #1386

Question

Running this command: ./docker/cluster/cluster_interface.sh job --task Isaac-Velocity-Rough-Anymal-C-v0 --headless --video --enable_cameras in a SLURM cluster left me with this issue in the error log:

WARNING: nv files may not be bound with --writable
WARNING: By using --writable, Singularity can't create /n destination automatically without overlay or underlay
FATAL:   container creation failed: mount /var/lib/singularity/mnt/session/n->/n error: while mounting /var/lib/singularity/mnt/session/n: destination /n doesn't exist in container

I tried removing the --writable flag, which caused additional issues with accessing or writing to directories (/isaac-sim). i.e. 

[omni.kit.stage_templates.new_stage] Failed to create directory /isaac-sim/kit/data/documents/Kit/apps/Isaac-Sim/scripts/new_stage
2024-11-06 19:44:04 [9,435ms] [Error] [omni.kit.app.plugin] failed to open file '/isaac-sim/kit/data/Kit/Isaac-Sim/4.2/user.config.json' - unable to save the dictionary

@pascal-roth would you know something about this?

pascal-roth commented 2 days ago

The '--writable' flag is necessary. I will try to reproduce this error on my side. To do so, could you please tell me which docker and singularity version you used to create the singularity image.

Hi @pascal-roth, These are the versions. Docker version: 27.3.1 Singularity version: 1.3.4 Apptainer version: 1.3.4
