我通过Python设置了使用Google Vision API，但它不起作用，我找不到任何好的解决方案。无论我做什么，我总是得到"AttributeError: module 'google.cloud.vision' has no attribute 'types'"。。。
下面是我使用的代码示例(完成身份验证等(。
from __future__ import print_function
from google.cloud import vision
from google.cloud.vision import types
image_uri = 'gs://cloud-samples-data/vision/using_curl/shanghai.jpeg'
client = vision.ImageAnnotatorClient()
image = types.Image(content=IMAGE_CONTENT)
label_results = client.label_detection(image=image)
response = client.label_detection(image=image)
print('Labels (and confidence score):')
print('=' * 30)
for label in label_results.label_annotations:
print(f'{label.description} - {label.score}')
这是我的点子冻结：

有什么想法吗？
我认为您应该遵循官方文档：
视觉客户端库
import io
import os
# Imports the Google Cloud client library
from google.cloud import vision
# Instantiates a client
client = vision.ImageAnnotatorClient()
# The name of the image file to annotate
file_name = os.path.abspath('resources/wakeupcat.jpg')
# Loads the image into memory
with io.open(file_name, 'rb') as image_file:
content = image_file.read()
image = vision.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)
它用于创建视觉模块的图像：
image = vision.Image(content=content)
not
image = types.Image(content=IMAGE_CONTENT)
这应该是答案，因为Google Vision更改了Type和Emun方法。我也遇到了这个问题，因为当你需要来自pdf/img文件的文本数据时，愿景-1和愿景-2有一些不同。
import json
import re
from google.cloud import vision
from google.cloud import storage
# Supported mime_types are: 'application/pdf' and 'image/tiff'
mime_type = 'application/pdf'
# How many pages should be grouped into each json output file.
batch_size = 2
client = vision.ImageAnnotatorClient()
feature = vision.Feature(
type_=vision.Feature.Type.DOCUMENT_TEXT_DETECTION)
gcs_source = vision.GcsSource(uri=gcs_source_uri)
input_config = vision.InputConfig(
gcs_source=gcs_source, mime_type=mime_type)
gcs_destination = vision.GcsDestination(uri=gcs_destination_uri)
output_config = vision.OutputConfig(
gcs_destination=gcs_destination, batch_size=batch_size)
async_request = vision.AsyncAnnotateFileRequest(
features=[feature], input_config=input_config,
output_config=output_config)
operation = client.async_batch_annotate_files(
requests=[async_request])
print('Waiting for the operation to finish.')
operation.result(timeout=420)
# Once the request has completed and the output has been
# written to GCS, we can list all the output files.
storage_client = storage.Client()
match = re.match(r'gs://([^/]+)/(.+)', gcs_destination_uri)
bucket_name = match.group(1)
prefix = match.group(2)
bucket = storage_client.get_bucket(bucket_name)
# List objects with the given prefix.
blob_list = list(bucket.list_blobs(prefix=prefix))
print('Output files:')
for blob in blob_list:
print(blob.name)
# Process the first output file from GCS.
# Since we specified batch_size=2, the first response contains
# the first two pages of the input file.
output = blob_list[0]
json_string = output.download_as_string()
response = json.loads(json_string)
# The actual response for the first page of the input file.
first_page_response = response['responses'][0]
annotation = first_page_response['fullTextAnnotation']
# Here we print the full text from the first page.
# The response contains more information:
# annotation/pages/blocks/paragraphs/words/symbols
# including confidence scores and bounding boxes
print('Full text:n')
print(annotation['text'])
