cx_Freeze "ImportError: cannot import name 'vision"

Question

我正在尝试冻结的 Python 脚本中使用 TensorFlow。一切都很好，但是当我尝试运行它时，我收到了这个错误：

Traceback (most recent call last):
File "C:\Users\.conda\envs\lib\site-packages\cx_Freeze\initscripts__startup__.py", line 14, in run module.run()
File "C:\Users\.conda\envs\lib\site-packages\cx_Freeze\initscripts\Console.py", line 26, in run exec(code, m.dict)
File "config.py", line 21, in
File "E:\Projects\test.py", line 7, in from google.cloud import vision
ImportError: cannot import name 'vision'

我正在使用 cx_Freeze。 google 库已成功添加到Setup.py 脚本中。 __init__.py 也存在于 google 目录中。

Setup.py:

from cx_Freeze import setup, Executable
import sys
import os

base = None
os.environ['TCL_LIBRARY'] = "C:\\ProgramData\\Anaconda3\\tcl\\tcl8.6"
os.environ['TK_LIBRARY'] = "C:\\ProgramData\\Anaconda3\\tcl\\tk8.6"
os.environ["REQUESTS_CA_BUNDLE"] = os.path.join(os.getcwd(), "cacert.pem")

if sys.platform == 'win32':
    # base = "Win32GUI"
    base = 'Console'

if sys.platform == 'win64':
    # base = "Win64GUI"
    base = 'Console'

include = ['numpy.core._methods', 'numpy.lib.format', 'jinja2', 'jinja2.ext', 'asyncio', 'constants', 'jinja2.debug']

packages = ['asyncio', 'jinja2', 'jinja2.ext', 'flask', 'numpy', 'pandas', 'connect_db', 'pymysql', 'pymysql.cursors',
            'multiprocessing', 'multiprocessing.pool','google']
excludes = []

options = {'build_exe': {'packages': packages, 'includes': include, 'include_files': includefiles, 'excludes': excludes}}

flaskapp = Executable(script="config.py",
                      targetName="test.exe",
                      icon='test.ico'
                      )

setup(
    name="",
    version="1.0",
    author="Test",
    description="Test",
    options={
        'build_exe': {
            'include_files': includefiles,
            'includes': include,
            'packages': packages,
            'excludes': excludes,
            'build_exe': "build"
        }
    },
    executables=[flaskapp]
)

提前谢谢你

Answer 1

根据 GitHub 存储库，google/cloud/__init__.py 包含以下代码：

try:
    import pkg_resources

    pkg_resources.declare_namespace(__name__)
except ImportError:
    import pkgutil

    __path__ = pkgutil.extend_path(__path__, __name__)

cx_Freeze 可能无法识别此动态导入。尝试将'pkg_resources' 或'pkgutil' 添加到安装脚本中的'packages' 列表中。

编辑：

当google-cloud-vision 与 pip 一起安装时，path_to_python_lib/site-packages/google/cloud/ 目录中也缺少 __init__.py 文件。尝试在冻结之前手动将一个空的__init__.py 文件添加到此目录。

谢谢@jpeg 我终于找到了解决办法。

1. 我在/site-packages/google 和/site-packages/google/cloud 中添加了__init__.py
2. 对于错误：DistributionNotFound: The 'google-api-core' distribution was not found and is required by the application 编辑了/site-packages/google/api_core/__init__.py

import requests_toolbelt.adapters.appengine
requests_toolbelt.adapters.appengine.monkeypatch()
import pkg_resources
old_get_distribution = pkg_resources.get_distribution
from pkg_resources import parse_version

def mp_get_distribution(*args, **kwargs):
    # print args
    # print kwargs
    try:
        res = old_get_distribution(*args, **kwargs)
    except:
        class Mock(object):
            pass

        mock = Mock()
        mock.parsed_version = parse_version("2.6.1") #add sensible value
        mock.version = parse_version("2.6.1") #add sensible value
        return mock

    return res

pkg_resources.get_distribution = mp_get_distribution

from google import api_core

Answer 3

我不得不修改A14提出的解决方案如下。

1. 在 /site-packages/google 中添加 init.py 也在 /site-packages/google/cloud 中（相同）

2. 在 init.py 中 /site-packages/pkg_ressources 在导入后添加这一行

   from pkg_resources import py2_warn
   

3. 对于错误：DistributionNotFound：未找到“google-api-core”分发，应用程序需要编辑 /site-packages/google/api_core/init.py

    import pkg_resources
    old_get_distribution = pkg_resources.get_distribution
    from pkg_resources import parse_version
   
    def mp_get_distribution(*args, **kwargs):
        # print args
        # print kwargs
        try:
            res = old_get_distribution(*args, **kwargs)
        except:
            class Mock(object):
               pass
   
             mock = Mock()
             mock.parsed_version = parse_version("1.16.0") #add sensible value
             mock.version = parse_version("1.16.0") #add sensible value
             return mock
   
        return res
   
   pkg_resources.get_distribution = mp_get_distribution
   
   from google import api_core
