Dependencies

• meson-python
• numpy
• pandas
• scipy
• openalea.plantgl
• openalea.mtg
• QtPy

Modifications

• Installation with make: it compiles fortran part with f2py then installs the package with setuptools and pip
• Compute transmitted radiation for each voxel
• Intercepted and transmitted radiation among the output results
• leaf angle distribution for each voxel
• Local or solar hour option for computing sun position
• Possibility for external use of the sun computation routine

Installation

for user

1. Install Miniforge: https://github.com/conda-forge/miniforge
2. Create a conda environment:

mamba create -n pyratp openalea.ratp -c conda-forge -c openalea3

3. activate the environment: mamba activate pyratp

The user has the possibility to install the package from a candicate release channel of the conda repository of openalea as follows:

mamba create -n pyratp openalea.ratp -c conda-forge -c openalea3/label/rc

The rc channel corresponds to the latest build of PyRatp when the main channel is the stable release.

For developpers

Editable install with conda/environment.yml is not functionning because of namespace conflict. A workaround is as follow:

1. download the repository and change to the root directory:

   git clone https://github.com/openalea/PyRATP.git
   cd PyRATP

2. Create a conda environment with dependencies manually with:

mamba create -n pyratp  -c openalea3 -c conda-forge  openalea.plantgl openalea.mtg qtpy compilers meson-python gfortran openalea.mtg

3. activate the environment: mamba activate pyratp

4. Build the fortran library:

meson setup builddir
meson compile -C builddir
cp builddir/src/openalea/ratp/pyratp.cpython-31*.so src/openalea/ratp

5. modify the Python path: via the environment variable

export PYTHONPATH="$PWD/src":$PYTHONPATH

or

add the path to src in your ipython or in IDE with:

import sys; sys.path.extend([mypath to 'src'])

with mypath to 'src' the absolute path to 'PyRatp/src'
