dlc2action 0.2b3

tba

DLC2Action is an action segmentation package that makes running and tracking of machine learning experiments easy.

Installation

Via the Python Package Index

You can simply install DLC2Action by typing:

pip install "dlc2action==0.2b3"

From Github

You can install DLC2Action for development by running this in your terminal.

git clone https://github.com/AlexEMG/DLC2Action
cd DLC2Action
conda create --name DLC2Action python=3.9
conda activate DLC2Action
python -m pip install .

Features

The functionality of DLC2Action includes:

• compiling and updating project-specific configuration files,
• filling in configuration dictionaries automatically whenever possible,
• saving training parameters and results,
• running predictions and hyperparameter searches,
• creating active learning files,
• loading hyperparameter search results in experiments and dumping them into configuration files,
• comparing new experiment parameters with the project history and loading pre-computed features (to save time) and previously created splits (to enforce consistency) when there is a match,
• filtering and displaying training, prediction and hyperparameter search history,
• plotting training curve comparisons

and more.

A quick example

You can start a new project, run an experiment, visualize it and use the trained model to make a prediction in a few lines of code.

from dlc2action.project import Project

# create a new project
project = Project('project_name', data_type='data_type', annotation_type='annotation_type',
                  data_path='path/to/data/folder', annotation_path='path/to/annotation/folder')
# set important parameters, like the set labels you want to predict
project.update_parameters(...)
# run a training episode
project.run_episode('episode_1')
# plot the results
project.plot_episodes(['episode_1'], metrics=['recall'])
# use the model trained in episode_1 to make a prediction for new data
project.run_prediction('prediction_1', episode_names=['episode_1'], data_path='path/to/new_data/folder')
