paddlex本来是为了简化ai模型使用应运而生的，但是很长一段时间，都感觉它反而更难用。这回静下心来尝试一下
手册看这里：PaddleX 文档
repo:
PaddlePaddle/PaddleX: All-in-One Development Tool based on PaddlePaddle
先在星河社区进行实践。
安装
pip install "paddlex[base]"果然，上来就碰到了问题
我在星河社区的项目里（是通过AI助手进来的项目，不是以前自己创立的项目），直接安装了paddlex之后，执行报错：
/bin/bash: paddlex: command not found执行
到系统里，发现paddlex的执行文件在这个目录：
/home/aistudio/external-libraries/bin ,到这个目录去执行：./paddlex --pipeline OCR \
--input https://paddle-model-ecology.bj.bcebos.com/paddlex/imgs/demo_image/general_ocr_002.png \
--use_doc_orientation_classify False \
--use_doc_unwarping False \
--use_textline_orientation False \
--save_path ./output \
--device gpu:0发现卡住了
再执行一次，报错：
Pipeline prediction failed
Traceback (most recent call last):

NotImplementedError: (Unimplemented) ConvertPirAttribute2RuntimeAttribute not support [pir::ArrayAttribute<pir::DoubleAttribute>] (at /paddle/paddle/fluid/framework/new_executor/instruction/onednn/onednn_instruction.cc:116)
据说是框架不兼容导致的，临时解决方案是设置FLAGS_use_onednn=0
可以这样设置
import os
os.environ['FLAGS_use_onednn'] = '0'对我们这个，这样设置
FLAGS_use_onednn=0 ./paddlex --pipeline OCR \
--input https://paddle-model-ecology.bj.bcebos.com/paddlex/imgs/demo_image/general_ocr_002.png \
--use_doc_orientation_classify False \
--use_doc_unwarping False \
--use_textline_orientation False \
--save_path ./output \
--device cpu还是同样的报错
飞桨版本是3.3
pip show paddlepaddle
Name: paddlepaddle
Version: 3.3.0
在windows下安装测试
python -m pip install paddlex
python -m pip install paddlepaddle==3.3.0 -i https://www.paddlepaddle.org.cn/packages/stable/cpu/然后执行
paddlex --pipeline OCR --input https://paddle-model-ecology.bj.bcebos.com/paddlex/imgs/demo_image/general_ocr_002.png --use_doc_orientation_classify False --use_doc_unwarping False --use_textline_orientation False --save_path ./output --device cpu报错，说没有paddle，得，python3.14下好像还装不了飞桨...
第二天可以执行paddlex了
paddlex
Checking connectivity to the model hosters, this may take a while. To bypass this check, set `PADDLE_PDX_DISABLE_MODEL_SOURCE_CHECK` to `True`.

可能是飞桨不支持python3.14吧。换到python3.12环境下安装只用paddlex

两个python环境有点串啊
