ivoryos 1.6.4

an open-source Python package enabling Self-Driving Labs (SDLs) interoperability

IvoryOS: open-source orchestrator for self-driving labs

IvoryOS turns existing Python automation code into interactive controls, drag-and-drop workflows, and optimization-ready experiments.

Build for fast-changing R&D environments, and make Python-based lab automation accessible and scalable.

Join our community!

IvoryOS is an open-source project under active development. We welcome feedback, feature ideas, and contributions from anyone working on or interested in self-driving laboratories.

Join our Discord or Slack to ask questions, share use cases, and help shape IvoryOS.

Installation

From PyPI:

pip install ivoryos

---

System Requirements

Platforms: Compatible with Linux, macOS, and Windows (developed/tested on Windows).
Python: Python ≥3.10

Dependency groups

• Core: Flask, Flask-Login, Flask-Session, Flask-SocketIO, Flask-SQLAlchemy, Flask-WTF, WTForms, SQLAlchemy-Utils, bcrypt, python-dotenv, pandas.
• Optimizers: optimizer-ax, optimizer-baybe, optimizer-nimo, or optimizers for all supported optimizer adapters.
• Database: db for PostgreSQL support.
• LLM design agent: llm for the optional in-app text-to-workflow feature.
• Development: dev for running the test suite.

Optional feature installs

pip install "ivoryos[optimizers]"       # all optimizer adapters
pip install "ivoryos[optimizer-ax]"     # Ax only
pip install "ivoryos[optimizer-baybe]"  # BayBE only
pip install "ivoryos[optimizer-nimo]"   # NIMO only
pip install "ivoryos[db]"               # PostgreSQL support
pip install "ivoryos[llm]"              # optional text-to-workflow design agent

From a local source checkout:

pip install -e ".[dev]"
pytest

32-bit Windows installation notes

Prefer 64-bit Python when possible. If you must deploy IvoryOS on 32-bit Windows, pip may not find pre-built 32-bit wheels for modern packages such as greenlet, pandas, or newer Flask-Session releases.

# 1. Use a Flask-Session release before the msgspec dependency.
pip install "Flask-Session<0.7"

# 2. Install a pandas wheel compatible with the local 32-bit Python environment.
pip install pandas --user --only-binary=:all:

# 3. Install greenlet from conda-forge if PyPI has no compatible wheel.
conda install -c conda-forge greenlet -y

# 4. Install IvoryOS.
pip install ivoryos

Quick start

In your script, where you initialize or import your robot:

my_robot = Robot()

import ivoryos

ivoryos.run(__name__)

Then run the script and visit http://localhost:8000 in your browser. Use admin for both username and password, and start building workflows!

---

Features

Direct control:

direct function calling Instruments tab

Workflows

• Design Editor: drag/add function to canvas in Workflow tab, use #parameter_name for dynamic parameters, click Prepare Run button to go to the execution configuration page
• Execution Config: configure iteration methods and parameters in Execution tab.
• Design Library: manage workflow scripts in Library tab.
• Workflow Data: Execution records are in Data tab.

Logging

Add single or multiple loggers:

ivoryos.run(__name__, logger="logger name")
ivoryos.run(__name__, logger=["logger 1", "logger 2"])

Human-in-the-loop

Use pause in flow control to pause the workflow and send a notification with custom message handler(s). When run into pause, it will pause, send a message, and wait for human's response. Example of a Slack bot:

def slack_bot(msg: str = "Hi"):
    """
    a function that can be used as a notification handler function("msg")
    :param msg: message to send
    """
    from slack_sdk import WebClient

    slack_token = "your slack token"
    client = WebClient(token=slack_token)

    my_user_id = "your user id"  # replace with your actual Slack user ID

    client.chat_postMessage(channel=my_user_id, text=msg)

import ivoryos
ivoryos.run(__name__, notification_handler=slack_bot)

Use Input in flow control to get human input during workflow execution. Example:

• ivoryos_data/:
  • config_csv/: Batch configuration csv
  • pseudo_deck/: Offline deck .pkl
  • results/: Execution results
  • scripts/: Compiled workflows Python scripts
  • default.log: Application logs
  • ivoryos.db: Local database
