Failed to pull singularity image

[DCossey]

Hello, I have just installed singularity along with all the dependencies. However, when I run the following command, I get the error below:

sudo snakemake --use-singularity --singularity-args '--bind /var/lib/minknow/data/pipeline_test/,/ ' -s /usr/local/software/lathe/Snakefile --configfile /usr/local/software/lathe/config.yaml --restart-times 0 --keep-going --latency-wait 30

File "/usr/lib/python3/dist-packages/snakemake/deployment/singularity.py", line 86, in pull

Any feedback on how I can get this to work? Have I written something wrong in the command?

Thanks,

Dan
