python - 导入错误 : cannot import name language in Google Cloud Language API

Question

我正在尝试使用 Google Natural Language API 中的示例代码来获取情绪分数。但是，每次运行代码时，我都会收到“ImportError:无法导入名称语言”。第一行错误。

我已经通过 pip 安装了该库，尝试卸载并重新安装，在控制台上创建凭据(API 显示为已启用)并查看了本教程并完成了答案中的这些步骤:Google sentiment analysis - ImportError: cannot import name language .它没有帮助。还有什么我可以尝试的吗？

from google.cloud import language
from google.cloud.language import enums
from google.cloud.language import types

client = language.LanguageServiceClient()

text = u'Hello, world!'
document = types.Document(
    content=text,
    type=enums.Document.Type.PLAIN_TEXT)

sentiment = client.analyze_sentiment(document=document).document_sentiment

print('Text: {}'.format(text))
print('Sentiment: {}, {}'.format(sentiment.score, sentiment.magnitude))

我还使用正确的路径将其粘贴到我的终端中。

export GOOGLE_APPLICATION_CREDENTIALS="/....(my path)/service_key.json"

Answer 1

这似乎是这个问题的重复:

Google sentiment analysis - ImportError: cannot import name language

对我来说，升级 google-api-python-client 和 google-cloud 还不够

相反，解决我的问题的是:

!pip install google-cloud-language

此外，当您升级 google api 库时，会出现与 awsebcli 库(来自 AWS)不兼容的错误。
