Question

我在Google Vision API中使用文档文本检测来获取文本从图像中获取，我有时会在运行程序并锁定笔记本电脑时收到“ google.api_core.exceptions.ServiceUnavailable：503名称解析失败”错误。看起来是网络问题，因为我无法使用同一张图片进行复制。我不明白为什么只有在笔记本电脑锁定时才会发生这种情况。

        client = vision.ImageAnnotatorClient()
        buffer = io.BytesIO()
        image.save(buffer, "PNG")
        content = buffer.getvalue()
        vision_type_image = vision.types.Image(content=content)
        response = client.document_text_detection(image=vision_type_image)
        document = response.full_text_annotation

    response = self.annotate_image(request, retry=retry, timeout=timeout)
  File "/home/sara/pip-envs/env/lib/python3.6/site-packages/google/cloud/vision_helpers/__init__.py", line 72, in annotate_image
    r = self.batch_annotate_images([request], retry=retry, timeout=timeout)

google.api_core.exceptions.ServiceUnavailable: 503 Name resolution failure```

获取google.api_core.exceptions.ServiceUnavailable：503屏幕锁定时名称解析失败
