Converting to Singularity image?

[KristofferK]

Has anyone successfully converted the dockerfile to a Singularity SIF file? This is needed to run it on SLURM without Docker access.

I have successfully been able to run the docker image locally, where I have access to Python, pip, torch, detectron2 module, etc. But when I convert it to Singularity, it seems some of the things are missing.

After converting to Singularity, Python 3.6.9 is installed, and I can do an "import detectron". That works. But pip is not installed, and "import torch" gives "ModuleNotFoundError: No module named 'torch'", "import "from detectron2 import model_zoo" gives "ImportError: cannot import name 'model_zoo'".

Has anyone created a Singularity image?
