* Add Python 3.13 support - Replace distutils imports with sysconfig/shutil/logging in ultra-infer setup - Replace pkg_resources with importlib.metadata in ultra-infer __init__ - Remove np.unicode_ usage (removed in NumPy 2.0, crashes on Python 3.13+) - Remove dead inspect.getargspec fallback (removed in 3.11) - Add python_requires=">=3.8" and Python 3.13 classifier to setup.py - Update Python version badges and docs from 3.8~3.12 to 3.8~3.13 - Pin PaddlePaddle to ==3.3.0 in install docs (first version with cp313 wheels) * CI: test Python bounds (3.8, 3.13) and revert HPI docs - CI matrix: test lower bound (3.8) and upper bound (3.13) per reviewer suggestion, with version-conditional PaddlePaddle install (3.2.0 for cp38, 3.3.0 for cp313) - Revert HPI docs to Python 3.8-3.12 since the package is separately compiled and does not yet support 3.13 * CI: add Python 3.9 to test matrix Test 3.9 as the lower bound for PaddlePaddle 3.3.0 (cp39-cp313). * Revert PaddlePaddle version bumps in docs due to 3.3.0 CPU inference bug Keep Python version range updates (3.8-3.13) but revert paddlepaddle install versions to their originals since 3.3.0 CPU native inference has a bug for paddleocr models. * Bump langchain-paddleocr version to 0.1.1 for Python 3.13+ support --------- Co-authored-by: Lin Manhui <mhlin425@whu.edu.cn>
PP-Structure Upgrade Considerations
Since its launch in 2021, the PP-Structure series models have undergone three generations of updates and iterations. Currently, the latest version is the third generation (PP-StructureV3). All the code and documentation on this page are based on the second generation (PP-StructureV2). This directory will be removed at an appropriate time in the future, and maintenance for the second generation will be discontinued.
The third generation, PP-StructureV3, offers more powerful document analysis capabilities, and we strongly recommend users to use this version via the integrated wheel package. For a detailed introduction to PP-StructureV3, please refer to the PP-StructureV3 Introduction Document; for specific usage instructions, please see the PP-StructureV3 Usage Guide.
In addition, we will discontinue maintenance of the KIE capability provided in the second generation. We recommend that you use the PP-ChatOCRv4 model in PaddleOCR 3.x, which offers more accurate key information extraction. For a detailed introduction to PP-ChatOCRv4, please refer to the PP-ChatOCRv4 Introduction Document; for specific usage instructions, please see the PP-ChatOCRv4 Usage Document.
PP-Structure 升级事项
PP-Structure 系列模型自 2021 年推出以来，已经历三代版本的更新迭代。目前，最新版本为第三代（PP-StructureV3）。本页面的所有代码与文档均基于第二代（PP-StructureV2），后续将在适当时机删除本目录，并停止对第二代的维护。
第三代 PP-StructureV3 提供了更为强大的文档解析能力，我们更推荐用户通过集成 wheel 包来使用该版本。关于 PP-StructureV3 的详细介绍，请参考PP-StructureV3 介绍文档；具体的使用方法可参见PP-StructureV3 使用文档。
另外，在第二代提供的 KIE 能力，我们也将停止维护，推荐大家使用 PaddleOCR 3.x 版本的 PP-ChatOCRv4 模型方案，关键信息抽取更准确。关于 PP-ChatOCRv4 的详细介绍，请参考PP-ChatOCRv4 介绍文档；具体的使用方法可参见PP-ChatOCRv4 使用文档。
