PaddleFSL

PaddleFSL is a Python library for few-shot learning (FSL) built upon PaddlePaddle 2.0.

• Provide various FSL solutions which are applicable to diverse applications.
• Contain detailed annotations and tutorial examples, such that users can easily develop and compare different FSL solutions.
• Can be easily deployed on various training platforms.

Overview

• paddlefsl: The proposed package for FSL.
  • paddlefsl.backbones: It provides representation learning models to extract sample representation, such as CNN, GNN and PLM.
  • paddlefsl.datasets: It provides publicly accessible benchmark few-shot datasets of diverse application scenarios, such as Omniglot, FewRel, FewGLUE and Tox21.
  • paddlefsl.model_zoo: It provides classical FSL models which particularly deal with the lack of labeled data, such as ProtoNet, MAML and PET.
  • paddlefsl.task_sampler: It provides APIs to split datasets into the typical N-way K-shot tasks.
  • paddlefsl.utils: It provides auxiliary APIs of PaddleFSL.
• examples: It provides examples of applying PaddleFSL to diverse application scenarios, such as computer vision tasks, natural language tasks and bioinformatics tasks.
• raw_data: It provides guides to download and place the raw data files.
• test: It provides unit test files of functions and classes.

Installation

To use our package, users should first install paddlepaddle-v2.0.0 or later versions, see https://www.paddlepaddle.org.cn/install .

First, install our required packages.

# Clone our repository.
git clone https://github.com/tata1661/FSL-Mate.git
# Install requirements.
cd FSL-Mate/PaddleFSL
pip install -r requirements.txt

Second, update environment variables.

# Please edit env.sh to set the correct path of FSL-paddletoolkit directory.
# Then do:
source env.sh
# If you want to use our package frequently, you can add environment variables into .bashrc
cat env.sh >> ~/.bashrc
source ~/.bashrc

Finally, check whether the installation is successful.

# Start a python interpreter
