docker error when using singularity image to run ks4

Start with spikeinterface/sorters/runsorter.py and spikeinterface/sorters/container_tools.py, especially run_sorter_container and ContainerClient._get_docker_image. Reproduce the Kilosort4 call using singularity_image=True on the reported Fedora setup, then inspect the linked FileNotFoundError traceback. Done means the singularity path no longer produces the reported Docker or file-not-found failure.

Hello,

i have been running ks4 with singularity successfully in the past week, but today i got an error saying docker module not found:

so then i installed docker, but got another error:

FileNotFoundError Traceback.txt

installed spikeinterface main on linux fedora 39.

Could someone please help? Thanks!
