FATAL: container creation failed

[ramadatta]

Hi,

Thank you very much for this package.

I have the following error when I run the tool using singularity.

$ which singularity 
/usr/local/bin/singularity

$ singularity --version
singularity version 3.6.3

$ singularity exec souporcell_latest.sif souporcell_pipeline.py -h
FATAL:   container creation failed: mount /proc/self/fd/3->/usr/local/var/singularity/mnt/session/rootfs error: while mounting image /proc/self/fd/3: failed to find loop device: could not attach image file to loop device: no loop devices available

I have tried the same commands with v2.5 mentioned here but without any luck.

May i know how to resolve this?
