Installation

1. Create and activate a clean Python environment.

   conda create -n mario python=3.12
   conda activate mario
   

2. Install MARIO from PyPI.

   pip install mariopy
   

   Note

   MARIO requires Python 3.11, 3.12 or 3.13 (>=3.11,<3.14). Python 3.14 and later are not supported: MARIO pins numpy==2.1.1, which supports Python only up to 3.13. Always specify a supported Python version when creating an environment, as in the example above.

Test the installation

Run a quick sanity check after the installation in a new Python session:

import mario
db = mario.load_test("IOT")
print(db)

If this runs without errors, the installation is working and MARIO can load the packaged test database.
