Introduction

TLlib is a powerful library offering a user-friendly API based on pure PyTorch, making it easier to develop and apply transfer learning algorithms. Its design is consistent with torchvision, so that developers can quickly adapt existing algorithms or create new ones.

Updates

On 2024-03-15, an offline version of the documentation was uploaded. You can download it here and unzip it for local access.

Please note that on 2023-08-09, a notice was issued about broken dataset links. You can find details in DATASETS.md.

Supported Methods

TLlib includes several transfer learning methods organized under key categories:

• Domain Alignment: tllib.alignment
• Domain Translation: tllib.translation
• Self-Training: tllib.self_training
• Regularization: tllib.regularization
• Data Reweighting: tllib.reweight
• Model Ranking: tllib.ranking
• Normalization: tllib.normalization

Installation

To install TLlib, choose one of the following methods:

1. Install from Source Code

Clone the library and run the following commands:

git clone https://github.com/thuml/Transfer-Learning-Library.git
cd Transfer-Learning-Library
python setup.py install
pip install -r requirements.txt

2. Install via Pip

This method is currently experimental:

pip install -i https://test.pypi.org/simple tllib==0.4

Documentation

The complete API documentation can be accessed on the official website: Documentation.

How to Use TLlib

Here is a general analogy to understand how to use TLlib in your projects: Imagine TLlib as a toolbox for building furniture. Just like you can use many tools in different combinations to create a beautiful piece of furniture, TLlib allows you to apply different learning algorithms to effectively construct your model.

To train an algorithm (like a table with a specific design), you simply run:

python dann.py data/office31 -d Office31 -s A -t W -a resnet50 --epochs 20

Troubleshooting

If you encounter any issues with TLlib, here are a few troubleshooting tips:

• Ensure you’ve installed all required packages listed in requirements.txt.
• Check your Python version; TLlib may have compatibility requirements.
• If datasets fail to download, verify your internet connection or consult the DATASETS.md for alternative links.
