Operation returned an invalid status code 'Unauthorized' uploading training images to custom vision

Question

I'm trying to complete this sketch2code tutorial by AI School https://aischool.microsoft.com/en-us/services/learning-paths/sketch2code/sketch2code-lab/train-an-object-detection-model

Step 9 of the tutorial says:

Enter the command dotnet run and press the enter key.

I'm using Visual Studio 2019 could that be the problem?

Answer 1

You have to update Microsoft.Azure.CognitiveServices.Vision.CustomVision.Training package.

1. Open your terminal and go to the Import folder

2. Run the following command dotnet add package Microsoft.Azure.CognitiveServices.Vision.CustomVision.Training --version 2.0.0

3. Open Program.cs and replace this line:

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

   with this line:

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

   make sure to replace ENDPOINT with your yours from customvision.ai
