PaddleSeg

[2021-06-19] PaddleSeg Team won the AutoNUE 2021 Challenge: Semantic Segmentation Track in CVPR 2021! Technical Report can be found here. Code will be coming soon.

Welcome to PaddleSeg! PaddleSeg is an end-to-end image segmentation development kit developed based on PaddlePaddle, which covers a large number of high-quality segmentation models in different directions such as high-performance and lightweight. With the help of modular design, we provide two application methods: Configuration Drive and API Calling. So one can conveniently complete the entire image segmentation application from training to deployment through configuration calls or API calls.

Core features

High performance model: Based on the high-performance backbone trained by Baidu's self-developed semi-supervised label knowledge distillation scheme (SSLD), combined with the state of the art segmentation technology, we provides 50+ high-quality pre-training models, which are better than other open source implementations.

Modular design: PaddleSeg support 15+ mainstream segmentation networks, developers can start based on actual application scenarios and assemble diversified training configurations combined with modular design of data enhancement strategies, backbone networks, loss functions and other different components to meet different performance and accuracy requirements.

High efficiency: PaddleSeg provides multi-process asynchronous I/O, multi-card parallel training, evaluation and other acceleration strategies, combined with the memory optimization function of the PaddlePaddle, which can greatly reduce the training overhead of the segmentation model, all this allowing developers to lower cost and more efficiently train image segmentation model.

Installation

step 1. Install PaddlePaddle

System Requirements:

• PaddlePaddle >= 2.0.0
• Python >= 3.6+

Highly recommend you install the GPU version of PaddlePaddle, due to large overhead of segmentation models, otherwise it could be out of memory while running the models. For more detailed installation tutorials, please refer to the official website of PaddlePaddle。

step 2. Install PaddleSeg

Support to construct a customized segmentation framework with API Calling method for flexible development.

pip install paddleseg

step 3. Download PaddleSeg repo

Support to complete the whole process segmentation application with Configuration Drive method, simple and fast.

git clone https://github.com/PaddlePaddle/PaddleSeg

step 4. Verify installation

Run the following command. If you can train normally, you have installed it successfully.

python train.py --config configs/quick_start/bisenet_optic_disc_512x512_1k.yml
