Question

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

的此sketch2code教程

教程的第9步说：

输入运行命令dotnet，然后按Enter键。

我正在使用Visual Studio 2019可能是问题所在吗？

Answer 1

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

打开您的终端并转到“导入”文件夹
运行以下命令dotnet add package Microsoft.Azure.CognitiveServices.Vision.CustomVision.Training --version 2.0.0
打开Program.cs并替换以下行：

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

有这行：

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

请确保使用customvision.ai
中的ENDPOINT替换您的ENDPOINT

操作返回了无效的状态码“未经授权”，将训练图像上传到自定义视觉
