- ダウンロードしたキーファイル(なんちゃら.json)を適当なディレクトリに置いて, 以下を打つ(.bashrcにも入れておく)
$ export GOOGLE_APPLICATION_CREDENTIALS="そのファイルのパス"
$ pip3 install --upgrade google-cloud-vision
- 適当な画像を用意する(ファイル名は2020_0102_1316_dscn1374s.jpg):
- 以下のようなpythonスクリプトを書く(Googleのサンプルをちょっと改変; vision_test.py):
import io
import os
# Imports the Google Cloud client library
from google.cloud import vision
from google.cloud.vision import types
# Instantiates a client
client = vision.ImageAnnotatorClient()
# The name of the image file to annotate
file_name = os.path.join(
os.path.dirname(__file__),
'2020_0102_1316_dscn1374s.jpg') # ここだけ変える!!
print(file_name)
# Loads the image into memory
with io.open(file_name, 'rb') as image_file:
content = image_file.read()
image = types.Image(content=content)
# Performs label detection on the image file
response = client.label_detection(image=image)
labels = response.label_annotations
print('Labels:')
for label in labels:
print(label.description)
$ ipython3 vision_test.py
