Logs and results

Keep the workload ID returned by client.run(). You can use it later to check the run from any Python process signed in to the same account.

Wait for the result

Python

import nodus

with nodus.Client() as client:
    workload = client.get("YOUR_WORKLOAD_ID")
    done = workload.wait()
    print(done.status, done.cost_now_usd)
    if not done.succeeded:
        raise RuntimeError(f"Workload ended: {done.status}")
    print(done.logs())

wait() returns when the workload finishes, fails, or is cancelled. Check succeeded before using its results. Interactive waits show elapsed time, lifecycle events, live program output, and available training progress. Retrieve recorded output with logs(). If cancellation stops the run before a log artifact is committed, this call can return the retained live snapshot for up to 24 hours after termination. That snapshot is limited to 8 MiB per attempt and may omit output that had not reached Nodus before cancellation. Download it promptly if you need to keep it. A committed log artifact retains its normal retention.

Download files

When a stage omits output declarations, Nodus preserves non-empty outputs/ and results/ folders as outputs.tar and results.tar. Save the complete model bundle there, including weights, configuration and tokenizer files. Directories named .venv, venv, node_modules, .git, .nodus, __pycache__ and .cache are excluded recursively. Symbolic links and special files are skipped, so save model files directly into the folder rather than linking to a cache. Other locations require explicit output declarations, which replace automatic folder collection for that stage.

Download available results inside the client context after the workload completes:

Python

for path in done.download():
    print(path)

Files go into outputs/WORKLOAD_ID/STAGE/NAME by default, using the published output name. Pass a directory to done.download("results") to choose another location. For one file, use done.download_output("result", "result.json") with your declared output name. See output declarations when your program writes files outside the default folders. Default folder archives are downloaded as tar files and are not automatically extracted. Empty or absent default folders produce no archive. A script must actually save its model to disk for Nodus to preserve it.

Progress and cancellation

workload.status gives the last fetched status. Use workload.refresh() to update that handle or client.get(workload.id) to get a new one. For lifecycle updates, iterate over workload.stream_events(). These events describe execution progress, not your program's stdout.

Ctrl+C during a synchronous wait requests cancellation and remote resource cleanup. Cancelling an async wait() task also requests remote cancellation before re-raising the interruption. If cancellation cannot be confirmed, check the run and retry with await workload.cancel(). To cancel explicitly, call client.cancel(workload.id). A wait timeout ends local observation without cancelling the run.

From the terminal

Bash

nodus wait WORKLOAD_ID
nodus logs WORKLOAD_ID
nodus download WORKLOAD_ID

Check a workload without waiting with nodus status WORKLOAD_ID. Stop it with nodus cancel WORKLOAD_ID. Downloads include declared output files, not the entire container filesystem.

Live display

wait(progress=None) automatically enables a Rich display in an interactive terminal on Windows, macOS, and Linux. Use progress=True to enable output explicitly or progress=False for silent waiting. Progress goes to stderr and does not capture your program's stdout. Redirected output has no animations.

Elapsed time refreshes every second. Server updates are polled every two seconds by default. Recognized training output can show steps, epochs, loss, and throughput. Percentages appear only when a matching total is reported. For other programs, stage updates, elapsed time, and logs remain visible.

For a custom display, call client.live_logs(workload.id, after=cursor). It returns chunks, next_cursor, and truncated. Each chunk has a numeric ID, stage ID, generation, and text. Each response contains at most 16 chunks. Pass the returned cursor on the next request and keep reading until a page is empty. An empty page means there is no new output yet, not that the run has finished. Live capture is limited to 8 MiB per attempt, with explicit truncation. The live view is retained for 24 hours after termination. Saved logs retain their normal retention. Older runners show saved logs as they become available.

Live output combines stdout and stderr. Buffered programs may delay their own output. Python output is unbuffered unless explicitly overridden.

Existing local files

download() creates its destination directories and refuses to overwrite files. Choose a fresh directory if a previous download already exists. The lower-level download_output() requires an existing parent directory and replaces its target only after the complete download passes its integrity checks.
