c# - 操作返回无效状态代码“未授权”将训练图像上传到自定义视觉

Question

我正在尝试完成 AI School 的这个 sketch2code 教程https://aischool.microsoft.com/en-us/services/learning-paths/sketch2code/sketch2code-lab/train-an-object-detection-model

本教程的第 9 步说：

输入命令dotnet运行并按回车键。

我正在使用 Visual Studio 2019 这可能是问题吗？

Answer 1

您必须更新 Microsoft.Azure.CognitiveServices.Vision.CustomVision.Training 包。

1. 打开终端并转到导入文件夹

2. 运行以下命令dotnet add package Microsoft.Azure.CognitiveServices.Vision.CustomVision.Training --version 2.0.0

3. 打开 Program.cs 并替换这一行：

   TrainingApi trainingApi = new TrainingApi() { ApiKey = trainingKey };

   用这条线：

   CustomVisionTrainingClient trainingApi = new CustomVisionTrainingClient(new ApiKeyServiceClientCredentials(trainingKey)) {Endpoint = endpoint};

   确保用您来自customvision.ai的 ENDPOINT 替换
