没有名为api_core.protobuf_helpers的模块。python2.7和googlecloud

Question

我正在尝试the following example来测试具有语言自动检测功能的翻译。

它可以很好地与python3配合使用。

但当尝试使用python2.7时，它会失败，并显示以下消息：

python2.7 example.py multi-language
Traceback (most recent call last):
  File "google_example.py", line 295, in <module>
    transcribe_file_with_multilanguage()
  File "google_example.py", line 214, in transcribe_file_with_multilanguage
    from google.cloud import speech_v1p1beta1 as speech
  File "/usr/local/lib/python2.7/dist-packages/google/cloud/speech_v1p1beta1/__init__.py", line 17, in <module>
    from google.cloud.speech_v1p1beta1 import types
  File "/usr/local/lib/python2.7/dist-packages/google/cloud/speech_v1p1beta1/types.py", line 20, in <module>
    from google.api_core.protobuf_helpers import get_messages
ImportError: No module named api_core.protobuf_helpers

pip2 freeze | grep google的输出

google==2.0.2 
google-api-core==1.8.0
google-auth==1.6.3 
google-cloud-core==0.29.1 
google-cloud-speech==0.36.3 
googleapis-common-protos==1.6.0b9

Answer 1

程序包名称之间存在冲突。安装了google package后，您的环境将尝试从它而不是从google-api-core获取api_core.protobuf_helpers模块。

要解决这个问题，可以采用this answer的方法。卸载google软件包，然后使用不同的名称重新安装。

还要注意，您使用的是googleapis-common-protos python. library的beta pre-release。如果您想使用当前的稳定版本，请运行：

pip2 uninstall googleapis-common-protos
pip2 install googleapis-common-protos==1.5.8

Answer 2

谢谢大家！我按照建议卸载了所有的google python模块。我按照下面的顺序重新安装了它们。我遵循的顺序是：

sudo pip2 install google 
sudo pip2 install google-api-core 
sudo pip2 install google-auth 
sudo pip2 install google-cloud-core 
sudo pip2 install google-cloud-speech 
sudo pip2 install googleapis-common-protos

现在它可以工作了：{

python2.7 interpreter.py multi-language
