URL Tensorflow服务Python请求超出了最大重试次数

问题描述 投票：0回答：1

我已经训练了自己的模型，并使用以下代码运行了Docker容器：

docker run -t --rm -d -p 8501:8501 -v "%cd%/serving/tensorflow_serving/servables/tensorflow/testdata/optik_gpu:/models/optik_gpu" -e MODEL_NAME=optik_gpu tensorflow/serving

我正在使用Windows 10作为操作系统。

[我正在尝试将base64字符串发布到容器中以进行预测。这是我在Google Cloud上建议的代码：

导入base64进口io导入json导入请求

def container_predict(image_file_path, image_key, port_number=8501):

    with io.open(image_file_path, 'rb') as image_file:
        encoded_image = base64.b64encode(image_file.read()).decode('utf-8')

    instances = {
            'instances': [
                    {'image_bytes': {'b64': str(encoded_image)},
                     'key': image_key}
            ]
    }

    url = 'http://localhost:{}/v1/models/default:predict'.format(port_number)

    response = requests.post(url, data=json.dumps(instances))
    print(response.json())

container_predict("./test.jpg", 1)

当我运行脚本时，出现此错误：

我不知道是什么问题。

我将通过说我是所有这一切的新手，并且不确定一切如何工作来开头。

刚刚遇到了类似的问题，并查看了哪些端口已打开。原来我的Docker容器在8502上（不知道为什么我以为我已将其指定在8501上，如此处的教程https://cloud.google.com/vision/automl/docs/containers-gcs-tutorial?hl=en_GB所示）。因此，一旦我在python代码中将端口更改为8502，它就开始工作。

不确定是否会帮助您，但是我的代码现在可以正常工作了...现在，我只需要弄清楚发生了什么以及为什么发生！
