Method `LargeTrainLargeFaceListAsync` is not recognized. #110180

Closed shapeh closed 1 year ago

shapeh commented 1 year ago

It would help with a full and working sample code.

A few problem with the displayed code snippets:

'IFaceClient' does not contain a definition for 'TrainLargeFaceListAsync' and no accessible extension method 'TrainLargeFaceListAsync' accepting a first argument of type 'IFaceClient' could be found (are you missing a using directive or an assembly reference?)

  • TrainAsync returns voidbut is assigned to var status?
  • What NuGets / package references to include? Tried with Microsoft.Azure.CognitiveServices.Vision.Face 2.8.0-preview.3 but no luck.
  • In general, I would be so nice with a sample on how to train a facial recognition database, and then later on detect faces based on the trained model.

I'll need to get in contact with a developer to update this code. In the meantime, @shapeh , see this sample from the source library for an example of LargeFaceList training and use https://github.com/Azure/azure-sdk-for-net/blob/main/sdk/cognitiveservices/Vision.Face/tests/FaceFindSimilarTests.cs

Hi @shapeh, for now, I'd recommend you use a PersonDirectory instead. https://learn.microsoft.com/en-us/azure/ai-services/computer-vision/how-to/use-persondirectory This is our newer data structure solution, and it performs better with large data sets. The doc you mentioned uses an older version of the API. It will soon be retired or updated to use PersonDirectory
