I use Google cloud's Natural Language API from this link:
And I use this command in powershell :
$env:GOOGLE_APPLICATION_CREDENTIALS="D:\analyze_sentiment\MyFirstProject-bbe4f7bccb98.json"
Then I use this command in cmd:
set GOOGLE_APPLICATION_CREDENTIALS=D:\analyze_sentiment\MyFirstProject-bbe4f7bccb98.json
But when I use python code:
from google.cloud import language
from google.cloud.language import enums
from google.cloud.language import types
# Instantiates a client
client = language.LanguageServiceClient()
# The text to analyze
text = u'Hello, world!'
document = types.Document(
content=text,
type=enums.Document.Type.PLAIN_TEXT)
# Detects the sentiment of the text
sentiment = client.analyze_sentiment(document=document).document_sentiment
print('Text: {}'.format(text))
print('Sentiment: {}, {}'.format(sentiment.score, sentiment.magnitude))
The error message said:
raise exceptions.DefaultCredentialsError(_HELP_MESSAGE) google.auth.exceptions.DefaultCredentialsError: Could not automatically determine credentials. Please set GOOGLE_APPLICATION_CREDENTIALS or explicitly create credentials and re-run the application. For more information, please see https://developers.google.com/accounts/docs/application-default-credentials.
Why?
