Problems and solutions of paddleocr packaging

Situation 1

error

AssertionError: …/distutils/core.pyc

resolvent

reinstall setuptools Tools , The version I tried 58.0.0 Can solve this problem

pip install setuptools==58.0.0

Scenario two

error

When the package finishes running paddle\\fluid\\..\\libs problem

resolvent

The solution to a little violence is to attach importance to the virtual environment paddle And paddleocr Put it in the packed one exe In the same level directory .
When the above problems are solved , Next, there will be the following problems

ModuleNotFoundError: No module named 'shapely'
ModuleNotFoundError: No module named 'pyclipper'
ModuleNotFoundError: No module named 'skimage'
ModuleNotFoundError: No module named 'pywt'
ModuleNotFoundError: No module named 'imgaug'
ModuleNotFoundError: No module named 'imageio'
ModuleNotFoundError: No module named 'fasttext'
ModuleNotFoundError: No module named 'lmdb'

ModuleNotFoundError: No module named 'imghdr'  
ModuleNotFoundError: No module named 'fasttext_pybind'

ImportError: cannot import name 'signal' from 'scipy' (...\scipy\__init__.pyc)

This is because paddleocr There are too many libraries to call , pyinstaller Not all modules are packaged , It's time to
We manually package these modules

How to put... When packing exe What about the same level directory , You need to use Pyinstaller Next --add-data 了
The following is a code example of encapsulation

def get_extra_params():
    #  Project root 
    root_path = get_root_path()
    extra_data = [
        ("src\\res", "src\\res"),
        ("config", "config"),
        ("venv\\Lib\\site-packages\\Shapely.libs", "Shapely.libs"),
        ("venv\\Lib\\site-packages\\paddle", "paddle"),
        ("venv\\Lib\\site-packages\\paddleocr", "paddleocr"),
        ("venv\\Lib\\site-packages\\PIL", "PIL"),
        ("venv\\Lib\\site-packages\\pywt", "pywt"),
        ("venv\\Lib\\site-packages\\lmdb", "lmdb"),
        ("venv\\Lib\\site-packages\\shapely", "shapely"),
        ("venv\\Lib\\site-packages\\skimage", "skimage"),
        ("venv\\Lib\\site-packages\\pyclipper", "pyclipper"),
        ("venv\\Lib\\site-packages\\scipy", "scipy"),
        ("venv\\Lib\\site-packages\\imgaug", "imgaug"),
        ("venv\\Lib\\site-packages\\imageio", "imageio"),
        ("venv\\Lib\\site-packages\\attrdict", "attrdict")]
    params = []
    for item in extra_data:
        src_path = os.path.join(root_path, item[0])
        params.extend(["--add-data", f"{src_path};{item[1]}"])
    return params

among imghdr yes Python A file in the directory , Just call it directly in the program code

import imghdr
import shapely

Situation three

error

subprocess Error of . It is also the case that there are multiple exe The problem of

Solution

In this file in the virtual environment \site-packages\paddle\dataset\image.py

if six.PY3:
    import subprocess
    import sys
    import_cv2_proc = subprocess.Popen(
        [sys.executable, "-c", "import cv2"],
        stdout=subprocess.PIPE,
        stderr=subprocess.PIPE)
    out, err = import_cv2_proc.communicate()
    retcode = import_cv2_proc.poll()
    if retcode != 0:
        cv2 = None
    else:
        import cv2
else:
    try:
        import cv2
    except ImportError:
        cv2 = None

Delete the above code , Change to the following

try:
    import cv2
except ImportError:
    cv2 = None
