Quick summary

Hello !
I am a very newbie in Singularity/Docker environments,

FINN worked fluently with Docker and for some reasons I have to move to a machine without root permission. Thus, I found a potential solution with singularity

While trying to launch singularity container instead of Docker by following these steps : #868
I got the error below :

Downloading and extracting board files...
cp: cannot stat '/users/local/ismail_env/finn-dev/deps/avnet-bdf/*': No such file or directory
cp: cannot stat '/users/local/ismail_env/finn-dev/deps/xil-bdf/boards/Xilinx/rfsoc2x2': No such file or directory

FINN_SINGULARITY is set, launching Singularity container instead of Docker
INFO[0000] trying next host                              error="failed to authorize: failed to fetch oauth token: unexpected status: 403 Forbidden" host=ghcr.io
FATAL:   Unable to handle oras://ghcr.io/eki-project/experiment-manager/finn_apptainer_xilinx:dev uri: failed to get checksum for oras://ghcr.io/eki-project/experiment-manager/finn_apptainer_xilinx:dev: while resolving reference: failed to authorize: failed to fetch oauth token: unexpected status: 403 Forbidden

Steps to Reproduce

1 - clone dev-branch to local
2 - export environment variable export FINN_SINGULARITY=oras://ghcr.io/eki-project/experiment-manager/finn_apptainer_xilinx:dev
3 - running ./run-docker.sh

Thank you for your work and in advance your help

Hi, the public Singularity image build at oras://ghcr.io/eki-project/experiment-manager is no longer maintained.

I recommend to build your own Singularity image from the FINN Docker image of the version you need. We do it with these two commands:
docker build --no-cache -f docker/Dockerfile.finn --tag=finn_docker_export .
apptainer build finn_singularity_image.sif docker-daemon://finn_docker_export:latest

Then you can point FINN_SINGULARITY to the .sif file.
