poll() still calls a child that has exited but not been reaped alive, so a node that ended itself with os._exit left its corpse on the idle queue and the next call died on a broken pipe. Mark it the way the out-of-step paths already do, and _release replaces it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Fluksio
A node-based automation engine: flows, dashboards and batch runs, in one resident process with no infrastructure behind it.
pip install fluksio
fluksio serve
That is the whole installation — no Docker, no database server, no ports to
open. It keeps a SQLite database, a git repository of your flows and an
artifact store under ~/.fluksio, and prints an admin password once.
For data science
Your functions become nodes where they already live. Install Fluksio into the environment you work in and your nodes run on it — the packages are already there:
# myresearch/train.py
import fluksio
from fluksio import Port, node
@node(
requires=["dataset", Port("lr", "float")],
provides=[Port("loss", "float", stream=True), Port("weights", "artifact")],
device="gpu", device_policy="prefer",
)
def fit(dataset, lr, epochs=25):
for epoch in range(epochs):
loss = step(...)
yield {"loss": loss} # published as it happens, kept as a series
return {"weights": fluksio.save_artifact("weights.pt")}
# myresearch/pipeline.py
from fluksio import Flow, Port
from myresearch.train import fit
train = Flow("train", nodes=[prepare, fit, evaluate],
inputs=[Port("lr", "float", initial=0.01)], outputs=["score"])
fluksio login --url http://127.0.0.1:8000
fluksio sync myresearch
fluksio run train --lr 0.05 --wait
The decorators return your functions untouched, so everything stays callable,
testable and importable as what it was. A metric leaves through a declared
port rather than a logging call, which is why there is no log_metric(): the
run keeps the whole series, a chart can bind to it, and a downstream node can
consume it.
What else it does
- Flows — typed messages between nodes, wired by name, edited on a canvas or declared in code. Every change is a commit in a git repository you own.
- Runs — an experiment and a CI-style job are the same entity. Parameters, seed, result, per-node timings, artifacts and the commit it ran at.
- Dashboards — charts and controls bound to the same messages the flows carry, with no separate metrics pipeline.
- Remote workers —
pip install fluksio-workeron the GPU box; it dials out over one websocket, so nothing there has to be reachable.
