🧰 Installation Guide

This page shows you how to set up your environment to use Impress and run asynchronous pipelines with it.

We recommend using a virtual environment to isolate your dependencies.

---

📦 Step 1: Create a Python Environment

Make sure you have Python 3.8 or newer installed.
You can check your Python version with:

python3 --version

We recommend creating a virtual environment to keep dependencies clean.

Using venv

On Linux/Mac:

python3 -m venv impress-env
source impress-env/bin/activate

On Windows:

python -m venv impress-env
impress-env\Scripts\activate

Your shell prompt should now show (impress-env) indicating the environment is active.

---

🚀 Step 2: Install Impress

Install Impress and its required dependencies from PyPI:

pip install impress

Impress uses Radical AsyncFlow as its workflow backend.
If not installed automatically, you can install it explicitly:

pip install radical.asyncflow

---

🧪 Step 3: Verify Installation

Check that Impress is installed and importable:

python -c "from impress import ImpressManager; print('Impress is installed!')"

You should see:

Impress is installed!

---

🧬 Step 4: Run a Sample Pipeline

Now you’re ready to write and run your own pipelines!

---

🔄 Deactivate Environment

When you’re done, you can deactivate your virtual environment:

deactivate

Next time you want to work with Impress, just activate the environment again.
