SOS! Help! I cannot get enroot/pyxis to work: error: pyxis: error: a container with name "pyxis_nemo-25.07.gpt_oss" does not exist, and --container-image is not set

Start by reproducing the reported enroot import, create, list, and srun commands with the shown ENROOT_DATA_PATH and container names. Trace how pyxis resolves the --container-name value against the enroot containers, and consider the issue complete when the cause of the name mismatch is identified and documented or corrected with a verified srun invocation.

Hi there,

SOS! Could you please kindly help me? I just couldn't get pyxis work:

Thanks!

enroot import 'docker://nvcr.io#nvidia/nemo:25.07.gpt_oss'

enroot create --name pyxis_nemo-25.07.gpt_oss nvidia+nemo+25.07.gpt_oss.sqsh

And then since then I updated one of the sub-folders inside the container slightly by using the latest repo main branch, so I am not willing to directly to pull from NVIDIA registry in srun.
