-# PaddleX dygraph mode is ready! Static mode is set by default and dygraph graph code base is in [dygraph](https://github.com/PaddlePaddle/PaddleX/tree/develop/dygraph). If you want to use static mode, the version 1.3.10 can be installed by pip. The version 2.0.0rc0 corresponds to the dygraph mode.

 :hugs:  PaddleX integrated the abilities of **Image classification**, **Object detection**, **Semantic segmentation**, and **Instance segmentation** in the Paddle CV toolkits, and get through the whole-process development from **Data preparation** and **Model training and optimization** to **Multi-end deployment**. At the same time, PaddleX provides **Succinct APIs** and a **Graphical User Interface**. Developers can quickly complete the end-to-end process development of the Paddle in a form of **low-code**  without installing different libraries.
