Installation

Step 1: Install Conda

To use Conda packages like lenapy, you first need to install Miniconda or Anaconda. Miniconda is a lightweight option, while Anaconda includes many preinstalled data science packages.

To install Miniconda (recommended for minimal setup):

1. Go to the Miniconda download page.
2. Download the installer for your operating system (Windows, macOS, or Linux).
3. Run the installer and follow the prompts. Make sure to:
   • Add Conda to your system’s PATH (if asked).
   • Allow the installer to initialize Conda automatically.

After installation, open a terminal (or Anaconda Prompt on Windows) and verify that Conda is installed by running:

conda --version

Step 2: Install lenapy Using Conda

Once Conda is installed, you can install lenapy by following these steps:

1. Create a new Conda environment (recommended):

conda create -n lenapy_env python=3.11

2. Activate the environment:

conda activate lenapy_env

3. Install lenapy:

conda install -c conda-forge lenapy

This installs lenapy and its dependencies from the conda-forge channel.

Use

In your python code, simply import the library with ::

import lenapy

You can now use all the functionnalities of lenapy by adding the right suffixe after your Dataset or DataArray ::

import xarray as xr
import lenapy
ds = lenapy.utils.geo.rename_data(xr.tutorial.open_dataset('air_temperature'))
ds.air.lngeo.mean(['latitude','longitude'],weights=['latitude']).lntime.climato().plot()
