Unable to Pull Singularity Image from Specified URL

[Romisaa-Ali]

Issue Description: I am trying to pull a Singularity image from the URL library://zifanxu/ros_jackal_image/image:latest, but I am encountering issues. When I search for this image using Singularity, it appears not to be available for the amd64 architecture. thank you,

R.

I also could not pull a Singularity image when implementing this command

python3 train.py --config configs/e2e_default_TD3.yaml

I got this error

I understood the image was saved as cache in ~/.singularity. However, after runing this command,

./singularity_run.sh local_buffer/image:latest.sif python3 test_env.py

I got this error

ERROR  : Requesting capability set 0x000001ffffffffff while permitted capability set is 0x0000003fffffffff

Hi Usaywook,

Would you be able to pull an image using a separate command as follows? singularity pull --name <PATH_TO_THIS_REPO>/local_buffer/image:latest.sif library://zifanxu/ros_jackal_image/image:latest

After running this command, you should be able to see a file <PATH_TO_THIS_REPO>/local_buffer/image:latest.sif.

The image is not save in ~/.singularity, there might be some cache there though.

Let me know, thanks!
