runmonitor

Lean, local experiment tracker with a live, terminal-styled web dashboard. Import and go.

import runmonitor as rm

run = rm.init("my-experiment", config={"lr": 0.001, "batch_size": 32}, total_steps=1000)

for step in range(1000):
    loss, acc = train_step()
    run.log({"loss": loss, "accuracy": acc}, step)
    if step % 100 == 0:
        run.save("checkpoint.pt")

run.finish()

Open http://localhost:8080 — your loss curve is already live and drawing itself.

Install

pip install runmonitor                 # core
pip install "runmonitor[system]"       # + CPU/RAM tracking (psutil)

Then in any training script:

import runmonitor as rm

Or run the dashboard on its own (no training script needed):

runmonitor                 # opens the dashboard in your browser
python -m runmonitor       # equivalent, for a checkout/vendored copy
RUNMONITOR_PORT=9000 runmonitor   # pick a port (set before launch)

The dashboard

A single, evolving view in the empero black/purple palette:

API

# Start a run (creates the project if new)
run = rm.init(project: str, name: str | None = None,
              config: dict | None = None,
              total_steps: int | None = None) -> Run

run.log(metrics: dict[str, float], step: int)   # log metrics at a step
run.save(filepath: str) -> dict                  # save an artifact file
run.finish()                                     # mark finished
run.fail()                                       # mark crashed

Storage

Everything lives in ~/.runmonitor/:

• runs.db — SQLite database (WAL mode, thread-safe)
• artifacts/<run_id>/ — saved files per run

No database setup, no API keys, no cloud.

Requirements

• Python 3.10+
• Flask
• Chart.js (loaded from CDN in the dashboard)
• psutil (optional, for system metrics)

Publishing to PyPI (maintainers)

python -m pip install --upgrade build twine
python -m build                 # → dist/runmonitor-<version>.tar.gz + .whl
python -m twine check dist/*
python -m twine upload dist/*   # needs a PyPI account + API token

Bump version in pyproject.toml before each release.
