问题描述
尝试使用Google情感分析。以下是我从Google教程获得的代码。演示如何简单调用Natural Language API。
import argparse
from google.cloud汇入语言
def print_result(注释):
score = annotations.sentiment.score
magnitude = annotations.sentiment.magnitude
for enumerate(annotations.sentences)中的句子:
sentence_sentiment格式(
index,sentence_sentiment))
print('Overall Sentiment:'sentence.sentiment.score
print('Sentence {} has a bustment score of {}'。格式(
分数,大小))
返回0
print('情感:{}的分数,大小为{} '.format(
score,magnitude))
return 0
def analyze(movie_review_filename):
运行情绪分析请求文字与。
language_client = language.Client()
with open(movie_review_filename,'r')as review_file:
#实例化一个纯文本文档。
document = language_client.document_from_html(review_file.read())
#检测文档中的情绪。
annotations = document.annotate_text(include_sentiment = True,
include_syntax = False,
include_entities = False)
#打印结果
print_result(annotations)
if __name__ =='__main__':
parser = argparse.ArgumentParser(
description = __ doc__,
formatter_class = argparse.RawDescriptionHelpFormatter)
parser.add_argument(
'movie_review_filename',
help ='您想分析的电影评论的文件名。')
args = parser.parse_args()
analyze(args.movie_review_filename)
运行代码我收到以下错误:
from google.cloud import language
ImportError:没有模块名为cloud
解决方案
你需要安装实际的Googl e SDK Python模块。 google-cloud库是pip可安装的:
pip install --upgrade google-cloud

Trying to use Google Sentiment Analysis. Here is the code I got from the Google tutorial.
"""Demonstrates how to make a simple call to the Natural Language API."""
import argparse
from google.cloud import language
def print_result(annotations):
score = annotations.sentiment.score
magnitude = annotations.sentiment.magnitude
for index, sentence in enumerate(annotations.sentences):
sentence_sentiment = sentence.sentiment.score
print('Sentence {} has a sentiment score of {}'.format(
index, sentence_sentiment))
print('Overall Sentiment: score of {} with magnitude of {}'.format(
score, magnitude))
return 0
print('Sentiment: score of {} with magnitude of {}'.format(
score, magnitude))
return 0
def analyze(movie_review_filename):
"""Run a sentiment analysis request on text within a passed filename."""
language_client = language.Client()
with open(movie_review_filename, 'r') as review_file:
# Instantiates a plain text document.
document = language_client.document_from_html(review_file.read())
# Detects sentiment in the document.
annotations = document.annotate_text(include_sentiment=True,
include_syntax=False,
include_entities=False)
# Print the results
print_result(annotations)
if __name__ == '__main__':
parser = argparse.ArgumentParser(
description=__doc__,
formatter_class=argparse.RawDescriptionHelpFormatter)
parser.add_argument(
'movie_review_filename',
help='The filename of the movie review you\'d like to analyze.')
args = parser.parse_args()
analyze(args.movie_review_filename)
Running the code I receive the following error:
from google.cloud import languageImportError: No module named cloud
解决方案
You need to install the actual Google SDK Python module. The google-cloud library is pip install-able:
pip install --upgrade google-cloud
