如何在 Google App Engine (python) 中導入 Google Cloud 語音識別

Question

我想在我的 Google App Engine python 應用程序上使用 google.cloud 庫。 自從我在本地安裝了這個庫以來，我所有的測試都在我的本地工作。 我原以為 GAE 默認支持它，但它不受支持。

這是我得到的錯誤：

from google.cloud import speech
ImportError: No module named cloud

我查看了在https://cloud.google.com/appengine/docs/standard/python/tools/using-libraries-python-27添加 3rd 方庫

按照說明操作后，我又遇到了另一個錯誤。

我很難理解這一點。 如果您以前這樣做過，請告訴我如何在 GAE 中設置 google.cloud。

Answer 1

正如在另一篇關於在 App Engine Standard 中使用客戶端庫的Stack Overflow 帖子中已經回答的那樣，GAE Standard 不支持 Google 客戶端庫，因此您可以使用App Engine Flexible ，一個Compute Engine 實例或使用REST API （這也有一個適用於 App Engine 標准的 Python 庫）。

如果您特別需要使用google.cloud庫，則必須使用 App Engine Flexible 而不是 Standard，但如果您更願意使用 Standard 環境，下面我將分享使用 Cloud 的示例 App Engine Standard 應用程序的代碼語音 API 通過Google API Python 客戶端庫。 該庫不是 GAE 標准的內置庫，因此您必須將其作為第三方庫進行供應。 為此，您必須在本地應用程序的目錄中創建lib文件夾，以及我在下面共享的requirements.txt文件，然后使用命令pip install -t lib/ -r requirements.txt安裝此庫。

運行此示例 GAE 應用程序所需的文件：

要求.txt

google-api-python-client

appengine_config.py

from google.appengine.ext import vendor

# Add any libraries install in the "lib" folder.
vendor.add('lib')

應用程序.yaml

runtime: python27
api_version: 1
threadsafe: True

handlers:
- url: /.*
  script: main.app

主文件

import webapp2
from apiclient.discovery import build
from oauth2client.client import GoogleCredentials

class MainPage(webapp2.RequestHandler):
    # Presentation page
    def get(self):
        self.response.headers['Content-Type'] = 'text/plain'
        self.response.write('This is a sample App Engine Standard application working with Cloud Speech API! :)\n\nGo to /speechAPI to transcribe your audio file (you will need to upload it to one of your Cloud Storage buckets)!')

class Recognize(webapp2.RequestHandler):
    # Working with Python API Client Library (NOT NEW CLIENT LIBRARIES)
    def get(self):
        # Add credentials
        credentials = GoogleCredentials.get_application_default()
        service = build('speech', 'v1', credentials=credentials)

        # Methods available in: https://developers.google.com/resources/api-libraries/documentation/speech/v1/python/latest/index.html
        collection = service.speech()

        # Build the data structure JSON-like
        data = {}
        data['audio'] = {}
        data['audio']['uri'] = 'gs://<BUCKET>/<FOLDER>/<FILE>'
        data['config'] = {}
        data['config']['encoding'] = '<ENCODING>'
        data['config']['languageCode'] = '<LANGUAGE_CODE>'
        data['config']['sampleRateHertz'] = <SAMPLE_RATE>

        # Build the request and execute it
        request = collection.recognize(body=data)
        res = request.execute()

        # Webapp2 Response
        self.response.headers['Content-Type'] = 'text/plain'
        self.response.write(res)


app = webapp2.WSGIApplication([
    ('/', MainPage),
    ('/speechAPI', Recognize),
], debug=True)

此應用程序也可在本地開發服務器中運行，因此您可以在將其部署到 App Engine 之前使用命令dev_appserver.py app.yaml對其進行測試。

試試這個： sudo pip install --upgrade google-cloud-speech

或者：

我正在使用另一個圖書館，
這個方法對你有幫助嗎？

import speech_recognition as sp
import time

print("Say something!")

while True:
    rec = sp.Recognizer()
    with sp.Microphone() as mic:
        audio = rec.listen(mic)
    try:
        print(rec.recognize_google(audio))
    except sp.UnknownValueError:
        print("I cannot understand what you said")
        time.sleep(0.5)
        print("Say again")
    except sp.RequestError as e:
        print("Error".format(e))
    word = rec.recognize_google(audio)

    if word == 'goodbye':
        break

安裝：

sudo pip install SpeechRecognition

sudo pip install pyaudio

如果發現錯誤：

sudo apt-get install python-pyaudio

sudo apt-get install libjack-jackd2-dev portaudio19-dev

然后再說一遍：

sudo pip install pyaudio

如果您發現錯誤，請嘗試以下操作：

sudo pip install --upgrade pyaudio
