Image Classifier optimised for ecology use-cases

Lit Ecology Classifier

Documentation: https://lit-ecology-classifier.readthedocs.io/en/latest/ Lit Ecology Classifier is a machine learning project designed for image classification tasks. It leverages PyTorch Lightning for streamlined training and evaluation processes.

Features

• Easy configuration and setup
• Utilizes PyTorch Lightning for robust training and evaluation
• Supports training on multiple GPUs
• Test Time Augmentation (TTA) for enhanced evaluation
• Integration with Weights and Biases for experiment tracking

Installation

To install Lit Ecology Classifier, use pip:

pip install lit-ecology-classifier

Usage

Training

To train the model, use the following command:

python -m lit_ecology_classifier.main --max_epochs 20 --dataset phyto --priority config/priority.json

Inference

To run inference on unlabelled data, use the following command:

python -m lit_ecology_classifier.predict --datapath /path/to/data.tar --model_path /path/to/model.ckpt --outpath ./predictions/

Configuration

The project uses an argument parser for configuration. Here are some of the key arguments:

Training Arguments

• --datapath: Path to the tar file containing the training data.
• --train_outpath: Output path for training artifacts.
• --main_param_path: Main directory where the training parameters are saved.
• --dataset: Name of the dataset.
• --use_wandb: Use Weights and Biases for logging.
• --priority_classes: Path to the JSON file with priority classes.
• --balance_classes: Balance the classes for training.
• --batch_size: Batch size for training.
• --max_epochs: Number of epochs to train.
• --lr: Learning rate for training.
• --lr_factor: Learning rate factor for training of full body.
• --no_gpu: Use no GPU for training.

Inference Arguments

• --outpath: Directory where predictions are saved.
• --model_path: Path to the model file.
• --datapath: Path to the tar file containing the data to classify.
• --no_gpu: Use no GPU for inference.
• --no_TTA: Disable test-time augmentation.
