AgML is a comprehensive library for agricultural machine learning. Currently, AgML provides access to a wealth of public agricultural datasets for common agricultural deep learning tasks. In the future, AgML will provide ag-specific ML functionality related to data, training, and evaluation. Here's a conceptual diagram of the overall framework.
AgML supports both the TensorFlow and PyTorch machine learning frameworks.
To install the latest release of AgML, run the following command:
pip install agmlAgML is designed for easy usage of agricultural data in a variety of formats. You can start off by using the AgMLDataLoader to
download and load a dataset into a container:
import agml
loader = agml.data.AgMLDataLoader('apple_flower_segmentation')You can then use the in-built processing methods to get the loader ready for your training and evaluation pipelines. This includes, but is not limited to, batching data, shuffling data, splitting data into training, validation, and test sets, and applying transforms.
import albumentations as A
# Batch the dataset into collections of 8 pieces of data:
loader.batch(8)
# Shuffle the data:
loader.shuffle()
# Apply transforms to the input images and output annotation masks:
loader.mask_to_channel_basis()
loader.transform(
transform = A.RandomContrast(),
dual_transform = A.Compose([A.RandomRotate90()])
)
# Split the data into train/val/test sets.
loader.split(train = 0.8, val = 0.1, test = 0.1)The split datasets can be accessed using loader.train_data, loader.val_data, and loader.test_data. Any further processing applied to the
main loader will be applied to the split datasets, until the split attributes are accessed, at which point you need to apply processing independently
to each of the loaders. You can also turn toggle processing on and off using the loader.eval(), loader.reset_preprocessing(), and loader.disable_preprocessing()
methods.
You can visualize data using the agml.viz module, which supports multiple different types of visualization for different data types:
# Disable processing and batching for the test data:
test_ds = loader.test_data
test_ds.batch(None)
test_ds.reset_prepreprocessing()
# Visualize the image and mask side-by-side:
agml.viz.visualize_image_and_mask(test_ds[0])
# Visualize the mask overlaid onto the image:
agml.viz.visualize_overlaid_masks(test_ds[0])AgML supports both the TensorFlow and PyTorch libraries as backends, and provides functionality to export your loaders to native TensorFlow and PyTorch
formats when you want to use them in a training pipeline. This includes both exporting the AgMLDataLoader to a tf.data.Dataset or torch.utils.data.DataLoader,
but also internally converting data within the AgMLDataLoader itself, enabling access to its core functionality.
# Export the loader as a `tf.data.Dataset`:
train_ds = loader.train_data.export_tensorflow()
# Convert to PyTorch tensors without exporting.
train_ds = loader.train_data
train_ds.as_torch_dataset()You're now ready to use AgML for training your own models!

AgML aims to provide easy access to a range of existing public agricultural datasets The core of AgML's public data pipeline is
AgMLDataLoader. You can use the AgMLDataLoader or agml.data.download_public_dataset() to download
the dataset locally from which point it will be automatically loaded from the disk on future runs.
From this point, the data within the loader can be split into train/val/test sets, batched, have augmentations and transforms
applied, and be converted into a training-ready dataset (including batching, tensor conversion, and image formatting).
To see the various ways in which you can use AgML datasets in your training pipelines, check out the example notebook.
A core aim of AgML is to provide datasets in a standardized format, enabling the synthesizing of multiple datasets into a single training pipeline. To this end, we provide annotations in the following formats:
- Image Classification: Image-To-Label-Number
- Object Detection: COCO JSON
- Semantic Segmentation: Dense Pixel-Wise
