maestro-economics

CLI and SDK for the RA Data platform — datasets, compute, and experiments.

pip install maestro-economics
mecon --help
mecon resources
mecon submit . --resource cpu-4c-16gb

CPU runs support two modes:

# Lower-cost default; may restart, so long jobs must resume from durable progress.
mecon submit . --resource cpu-16c-32gb --mode standard

# Fewer infrastructure interruptions; CPU only, billed at the Stable rate.
mecon submit . --resource cpu-16c-64gb --mode stable

For CPU timeouts above four hours, save progress during the run, load it at startup, and confirm the contract at submission:

def run(ctx):
    state = ctx.load_checkpoint() or {"step": 0}
    for step in range(int(state["step"]), 100):
        # compute one restart-safe unit
        ctx.save_checkpoint(step=step + 1)
    return {"completed_steps": 100}

mecon submit . --resource cpu-16c-32gb --timeout 21600 --durable-resume

ctx.output_dir is also durable. Stable CPU reduces interruptions but does not replace checkpoint/resume logic for long jobs.
