Check our Breizhcrops Tutorial Colab Notebook for quick hands-on examples.

Install Breizhcrops as python package from PyPI!

pip install breizhcrops

If you use Windows, execute these lines.

git clone https://github.com/dl4sits/BreizhCrops.git
pip install torch==1.6.0 -f https://download.pytorch.org/whl/torch_stable.html
conda install gdal fiona geopandas
pip install .

This minimal working example

# import package
import breizhcrops as bzh

# initialize and download FRH04 data
dataset = bzh.BreizhCrops("frh04")

# get data sample
x, y, field_id = dataset[0]

# load pretrained model
model = bzh.models.pretrained("Transformer")

# create a batch of batchsize 1
x = x.unsqueeze(0)

# perform inference
y_pred = model(x)

downloads the FRH04 dataset partition (used for evaluation), loads a pretrained model and performs a prediction on the first sample.

Furthermore, for a detailed data analysis you can check the Hands-on Tutorial on Time Series. This is a Jupyter Notebook for timeseries data exploration with BreizhCrops benchmark.

Train a model via the example script train.py

python train.py TransformerEncoder --learning-rate 0.001 --weight-decay 5e-08 --preload-ram

This script uses the default model parameters from breizhcrops.models.TransformerModel. When training multiple epochs, the --preload-ram flag speeds up training significantly

The model implementations from this repository are based on the following papers and github repositories.

• TempCNN (reimplementation from keras source code ) Pelletier et al., 2019
• LSTM Recurrent Neural Network adapted from Rußwurm & Körner, 2017
• MS-ResNet implementation from Fei Wang
• TransformerEncoder implementation was originally adopted from Yu-Hsiang Huang GitHub, but later replaced by own implementation when torch.nn.transformer modules became available
• InceptionTime Fawaz et al., 2019
• StarRNN Turkoglu et al., 2019
• OmniscaleCNN Tang et al., 2020

The raw label data originates from

• Registre parcellaire graphique (RPG) of the French National Geographic Institute (IGN)
