ImportError:无法导入名称_args_from_interpreter_flags

Question

对于一个应用程序，我必须使用Google。我能够使用from google.cloud import vision并在我的电脑中做图像分析。但是，当我在开发服务器上部署我的应用程序时，我会出错：

File "C:\MyApp\detect.py", line 26, in <module>
    from google.cloud import vision
  File "C:\Anaconda2\lib\site-packages\google\cloud\vision\__init__.py", line 34, in <module>
    __version__ = get_distribution('google-cloud-vision').version
  File "C:\Program Files (x86)\Google\Cloud SDK\google-cloud-sdk\platform\google_appengine\lib\setuptools-0.6c11\pkg_resources.py", line 311, in get_distribution
    if isinstance(dist,Requirement): dist = get_provider(dist)
  File "C:\Program Files (x86)\Google\Cloud SDK\google-cloud-sdk\platform\google_appengine\lib\setuptools-0.6c11\pkg_resources.py", line 197, in get_provider
    return working_set.find(moduleOrReq) or require(str(moduleOrReq))[0]
  File "C:\Program Files (x86)\Google\Cloud SDK\google-cloud-sdk\platform\google_appengine\lib\setuptools-0.6c11\pkg_resources.py", line 666, in require
    needed = self.resolve(parse_requirements(requirements))
  File "C:\Program Files (x86)\Google\Cloud SDK\google-cloud-sdk\platform\google_appengine\lib\setuptools-0.6c11\pkg_resources.py", line 565, in resolve
    raise DistributionNotFound(req)  # XXX put more info here
DistributionNotFound: google-cloud-vision

创建包含以下内容的appengine_config.py文件时：

from google.appengine.ext import vendor
vendor.add('C:\Anaconda2\Lib\site-packages')

我正在犯错误：

File "C:\Users\MyApp\detect.py", line 26, in <module>
    from google.cloud import vision
  File "C:\Anaconda2\lib\site-packages\google\cloud\vision\__init__.py", line 36, in <module>
    from google.cloud.vision.client import Client
  File "C:\Anaconda2\lib\site-packages\google\cloud\vision\client.py", line 23, in <module>
    from google.cloud.vision._gax import _GAPICVisionAPI
  File "C:\Anaconda2\lib\site-packages\google\cloud\vision\_gax.py", line 17, in <module>
    from google.cloud.gapic.vision.v1 import image_annotator_client
  File "C:\Anaconda2\lib\site-packages\google\cloud\gapic\vision\v1\image_annotator_client.py", line 31, in <module>

  File "C:\Anaconda2\lib\site-packages\google\gax\__init__.py", line 36, in <module>
    import multiprocessing as mp

    from multiprocessing.util import SUBDEBUG, SUBWARNING
  File "C:\Anaconda2\lib\multiprocessing\util.py", line 41, in <module>
    from subprocess import _args_from_interpreter_flags
ImportError: cannot import name _args_from_interpreter_flags

当我尝试以下链接中提到的黑客时：

https://github.com/GoogleCloudPlatform/google-cloud-python/issues/1893

https://github.com/googleapis/gax-python/issues/149

https://gist.github.com/nilleb/419122f2f6f1228650dd2dccbd01c5af

我正在犯错误：

File "C:\Users\MyApp\detect.py", line 11, in <module>
    class DummyProcessing(ModuleType):
NameError: name 'ModuleType' is not defined

然后，我按照这里的指示：图书馆

并使用以下命令：

pip install -t lib google-cloud-vision==0.28.0

和更新的appengine_config.py文件：

from google.appengine.ext import vendor
vendor.add('lib')

我正在犯错误：

File "C:\Users\MyApp\detect.py", line 26, in <module>
    from google.cloud import vision
  File "C:\Anaconda2\lib\site-packages\google\cloud\vision\__init__.py", line 36, in <module>
    from google.cloud.vision.client import Client
  File "C:\Anaconda2\lib\site-packages\google\cloud\vision\client.py", line 23, in <module>
    from google.cloud.vision._gax import _GAPICVisionAPI
  File "C:\Anaconda2\lib\site-packages\google\cloud\vision\_gax.py", line 17, in <module>
    from google.cloud.gapic.vision.v1 import image_annotator_client
  File "C:\Anaconda2\lib\site-packages\google\cloud\gapic\vision\v1\image_annotator_client.py", line 31, in <module>

  File "C:\Anaconda2\lib\multiprocessing\util.py", line 41, in <module>
    from subprocess import _args_from_interpreter_flags
ImportError: cannot import name _args_from_interpreter_flags

然后，我按照这里的指示：在GAE中使用gcloud-python

并使用以下命令：

pip install -t vendor google-cloud-vision==0.28.0

我从这里复制了appengine_config.py和darth.py文件：https://github.com/dhermes/test-gcloud-on-gae/tree/8a850fb8b5676ca03e07c4f9dcfba5efb8c77b0a/application

    from subprocess import _args_from_interpreter_flags
ImportError: cannot import name _args_from_interpreter_flags

我不知道下一步该怎么办。我现在完全被困住了。

Answer 1

回溯表明，库安装在本地python (C:\Anaconda2\lib\site-packages\google\cloud\vision)中，而不是安装在应用程序本身中，因为它应该安装在标准的env应用程序中。

来自用于Python的客户端库

应用引擎 因为应用引擎Python运行时环境中没有安装Python库，所以它们必须是在您的应用程序中，就像第三方库一样。

来自复制第三方库

若要使用与运行库捆绑在内置库列表中的第三方库，请执行以下操作：

• 创建一个目录来存储第三方库，如lib/。 mkdir库
• 使用pip (版本6或更高版本)和-t <directory>标志将库复制到您在上一步中创建的文件夹中。例如： pip安装-t lib/ ..。

遵循整个监控程序，然后重试。

但是，从您引用的关于第149期的评论来看，您可能不得不等待这个问题得到解决：

App标准还不支持@nilleb grpc。
