PyInstaller未分析paddle隐式导入，打包后exe运行报错求助

问题描述 #

Python脚本使用PaddleOCR功能运行正常，但通过PyInstaller打包成exe文件后，运行exe时报错，错误信息如下：

Traceback (most recent call last):
  File "mri_ocr_core.py", line 1, in <module>
  File "connect_backend_core.py", line 12, in init connect_backend_core

尝试将paddle.fluid.proto.framework_pb2添加到hiddenimports中重新打包，但PyInstaller的输出信息中未显示对该隐式导入进行分析，问题依旧存在。

环境版本信息 #

Python 3.7.9
paddle-bfloat==0.1.7
paddleocr==2.6.0.1
paddlepaddle==2.3.2
pyinstaller==5.6.2
pyinstaller-hooks-contrib==2022.2

问题复现步骤 #

1. 安装Python 3.7.9
2. 安装CPU版本paddlepaddle：

python3 -m pip install paddlepaddle -i https://mirror.baidu.com/pypi/simple

3. 安装指定版本PaddleOCR：

pip install "paddleocr>=2.6.0.3"

4. 安装PyInstaller：

pip install pyinstaller

5. 创建测试脚本test.py：

from paddleocr import PaddleOCR,draw_ocr
ocr = PaddleOCR()
img_path = r'./66.png'
result = ocr.ocr(img_path, cls=True)
for idx in range(len(result)):
    res = result[idx]
    for line in res:
        print(line)

6. 执行打包命令：

pyinstaller test.py --noconfirm

7. 运行生成的test.exe，出现如下错误：

Traceback (most recent call last):
  File "paddle\fluid\ir.py", line 24, in <module>
  File "PyInstaller\loader\pyimod02_importers.py", line 499, in exec_module
  File "paddle\fluid\proto\pass_desc_pb2.py", line 16, in <module>
ModuleNotFoundError: No module named 'framework_pb2'

During handling of the above exception, another exception occurred:

  File "paddle\fluid\proto\pass_desc_pb2.py", line 16, in <module>
ModuleNotFoundError: No module named 'framework_pb2'
[15880] Failed to execute script 'test' due to unhandled exception!

8. 修改test.spec文件，添加hiddenimports：

hiddenimports = set()
hiddenimports = list(hiddenimports)
hiddenimports.extend(['paddle.fluid.proto.framework_pb2'])

a = Analysis(
    ['test.py'],
    pathex=[],
    binaries=[],
    datas=[],
    hiddenimports=hiddenimports,
    hookspath=[],
    hooksconfig={},
    runtime_hooks=[],
    excludes=[],
    win_no_prefer_redirects=False,
    win_private_assemblies=False,
    cipher=block_cipher,
    noarchive=False,
)

9. 重新打包：

pyinstaller test.spec --noconfirm

10. 查看PyInstaller输出信息，未发现对paddle.fluid.proto.framework_pb2模块的分析记录，exe运行仍报错。
