Do i need to run the slurm cluster for training MusicGen using dora ?

Is there a way to run musicGen training by using Dora without setting up slurm cluster ?

You can have a look at this to run manually the jobs without Slurm: https://github.com/facebookresearch/dora#multi-node-training-without-slurm

You won't be able to use the dora grid command use, although running the grid with dora grid GRID_NAME --dry_run --init will allow you to use the signature with the -f flag in the dora run commands, e.g.

torchrun [...] -m dora run -f SIG

Or for single machine training you can bypass torchrun entirely and just use the -d flag.

I'm trying to run from a single AWS node, using the -d flag (with a solver), but I hit a configuration error:

[...]

    raise ConfigKeyError(f"Missing key {key!s}")
omegaconf.errors.ConfigKeyError: Missing key aws
    full_key: aws

Is there a way around this? I thought the -d flag should ignore cluster info but it seems like AWS is being detected automatically.
