如何使用 Python 连接到基于 Web 的预测端点

Question

以下网页提供了使用 c#

预测端点的示例代码

https://docs.microsoft.com/en-us/azure/cognitive-services/custom-vision-service/use-prediction-api

using System;
using System.IO;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Threading.Tasks;

namespace CVSPredictionSample
{
    public static class Program
    {
        public static void Main()
        {
            Console.Write("Enter image file path: ");
            string imageFilePath = Console.ReadLine();

            MakePredictionRequest(imageFilePath).Wait();

            Console.WriteLine("\n\nHit ENTER to exit...");
            Console.ReadLine();
        }

        public static async Task MakePredictionRequest(string imageFilePath)
        {
            var client = new HttpClient();

            // Request headers - replace this example key with your valid Prediction-Key.
            client.DefaultRequestHeaders.Add("Prediction-Key", "<Your prediction key>");

            // Prediction URL - replace this example URL with your valid Prediction URL.
            string url = "<Your prediction URL>";

            HttpResponseMessage response;

            // Request body. Try this sample with a locally stored image.
            byte[] byteData = GetImageAsByteArray(imageFilePath);

            using (var content = new ByteArrayContent(byteData))
            {
                content.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream");
                response = await client.PostAsync(url, content);
                Console.WriteLine(await response.Content.ReadAsStringAsync());
            }
        }

        private static byte[] GetImageAsByteArray(string imageFilePath)
        {
            FileStream fileStream = new FileStream(imageFilePath, FileMode.Open, FileAccess.Read);
            BinaryReader binaryReader = new BinaryReader(fileStream);
            return binaryReader.ReadBytes((int)fileStream.Length);
        }
    }
}

如何使用 Python 代码完成？
