cx_Freeze "ImportError: cannot import name 'vision"

Question

我在我试图冻结的 Python 脚本中使用 TensorFlow。一切都很好，但是当我尝试运行它时，我得到这个错误：

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]
)

提前致谢

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__)

可能 cx_Freeze 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。

编辑：

显然 __init__.py 文件也从 path_to_python_lib/site-packages/google/cloud/ 目录中丢失，当 google-cloud-vision 使用 pip 安装时。尝试在冻结之前手动向该目录添加一个空的 __init__.py 文件。

Answer 2

谢谢@jpeg 我终于找到了解决方案。

我在 /site-packages/google 中也添加了 __init__.py /site-packages/google/cloud
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。

在/site-packages/google中添加init.py也在/site-packages/google/cloud中（相同）
in init.py in /site-packages/pkg_ressources import
后添加这一行
```
from pkg_resources import py2_warn
```

对于 Error:DistributionNotFound：未找到 'google-api-core' 分布，并且编辑 /site-packages/google/api_core/[=18 的应用程序需要该分布=]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
