测试代码

我是在华为昇腾910B3上测试的PPStructure。

import os
import cv2
from PIL import Image
#from paddleocr import PPStructure,draw_structure_result,save_structure_res
from paddleocr_asyncio import PPStructuretable_engine = PPStructure(show_log=True, image_orientation=True, use_npu=True) #use_npu=False可以使用cpu推理img_path = '/Users/fulva/Desktop/PicRec/table3.png'
img = cv2.imread(img_path)
result = table_engine(img)print(f"result:", result)

问题1： Cannot open file inference.json

完整的报错如下：

[2025/01/18 03:22:27] ppcls WARNING: The current running environment does not support the use of GPU. CPU has been used instead.
Traceback (most recent call last):File "/home/aicc/paddleocr/test_pps.py", line 7, in <module>table_engine = PPStructure(show_log=True, image_orientation=True, use_npu=False)
.......
RuntimeError: (NotFound) Cannot open file /root/.paddleclas/inference_model/PULC/text_image_orientation/inference.json, please confirm whether the file is normal.[Hint: Expected paddle::inference::IsFileExists(prog_file_) == true, but received paddle::inference::IsFileExists(prog_file_):0 != true:1.] (at /paddle/paddle/fluid/inference/api/analysis_config.cc:111)(MindIE_1.0.RC2) root@5e3540875002:/home/aicc/paddleocr# ls /root/.paddleclas/inference_model/PULC/text_image_orientation/
inference.pdiparams  inference.pdiparams.info  inference.pdmodel

报错很明显，找不到/root/.paddleclas/inference_model/PULC/text_image_orientation/inference.json这个文件，这个文件目录是自动下载的模型目录，的确没这个文件。应该是百度的模型格式改了，导致找不到。

参考：https://github.com/PaddlePaddle/PaddleClas/issues/3329

解决方法：

export FLAGS_enable_pir_api=0 

问题2：StridedSliceAssignD算子不支持

模型加载出错，查看plog看到如下打印

临时解决方案：https://gitee.com/ascend/modelzoo/issues/I6Y31Z?from=project-issue&search_text=StridedSliceAssignD

也就是将其它算子修改名字和配置假装是StridedSliceAssignD算子。我没事，网上说这个方法有效。
