Google Cloud Vision_v1无Feature属性报错及conda版本升级咨询

批量文件标注代码运行报错 #

从谷歌官网复制的批量文件标注代码如下：

import io
from google.cloud import vision_v1

def sample_batch_annotate_files(file_path="path/to/your/document.pdf"):
    """Perform batch file annotation."""
    client = vision_v1.ImageAnnotatorClient()
    # Supported mime_type: application/pdf, image/tiff, image/gif
    mime_type = "application/pdf"
    with io.open(file_path, "rb") as f:
        content = f.read()
    input_config = {"mime_type": mime_type, "content": content}
    features = [{"type_": vision_v1.Feature.Type.DOCUMENT_TEXT_DETECTION}]
    # The service can process up to 5 pages per document file. Here we specify
    # the first, second, and last page of the document to be processed.
    pages = [1, 2, -1]
    requests = [{"input_config": input_config, "features": features, "pages": pages}]
    response = client.batch_annotate_files(requests=requests)
    for image_response in response.responses[0].responses:
        print(u"Full text: {}".format(image_response.full_text_annotation.text))
        for page in image_response.full_text_annotation.pages:
            for block in page.blocks:
                print(u"\nBlock confidence: {}".format(block.confidence))
                for par in block.paragraphs:
                    print(u"\tParagraph confidence: {}".format(par.confidence))
                    for word in par.words:
                        print(u"\t\tWord confidence: {}".format(word.confidence))

运行后出现如下错误：

File "---", line 16, in sample_batch_annotate_files
features = [{"type_": vision_v1.Feature.Type.DOCUMENT_TEXT_DETECTION}]
AttributeError: module 'google.cloud.vision_v1' has no attribute 'Feature'

google-cloud-vision 1.0.1版本确实过低，与谷歌官网提供的新版代码不兼容，导致vision_v1.Feature属性找不到。

升级google-cloud-vision包 #

1. 首先激活你的conda环境：

conda activate 你的环境名称

2. 执行以下命令升级到指定版本（3.5.1）：

conda install -c conda-forge google-cloud-vision=3.5.1

3. 如果指定版本安装失败，可直接升级到最新兼容版本：

conda install -c conda-forge google-cloud-vision --update-all

验证升级结果 #

升级完成后，可在环境中执行以下命令确认版本：

conda list google-cloud-vision

确认版本更新后，重新运行代码即可解决属性找不到的错误。
