Im trying to use Microsoft.Azure.CognitiveServices.Vision.CustomVision.Prediction feature by submitting an image by using pickphoto cross media and geting a result of a predicition. I have tried to pass the image as url or a stream and keep getting a badrequest. I know that I have the correct prediction key and endpoint because i works for training telling me is the way I pass the image into the method. What is the correct way to transform the image from Cross Media pick photo package into the
private async void UplodatePictureButton_Clicked(object sender, EventArgs e)
{
await CrossMedia.Current.Initialize();
MediaFile file;
if (!CrossMedia.Current.IsPickPhotoSupported)
{
await DisplayAlert("No upload", "Picking a photo is not supported", "OK");
return;
}
file = await CrossMedia.Current.PickPhotoAsync();
if (file == null)
{
return;
}
MainImage.Source = ImageSource.FromStream(() =>
{
var stream = file.GetStream();
return stream;
});
// Create the Api, passing in the training key
CustomVisionTrainingClient trainingApi = new CustomVisionTrainingClient()
{
ApiKey = trainingKey,
Endpoint = SouthCentralUsEndpointTraining
};
var projects = trainingApi.GetProjects();
var project = projects.FirstOrDefault(p => p.Name == "Car");
CustomVisionPredictionClient endpoint = new CustomVisionPredictionClient()
{
ApiKey = predictionKey,
Endpoint = SouthCentralUsEndpointPrediction
};
var result = endpoint.ClassifyImageUrl(project.Id, project.Name, new Microsoft.Azure.CognitiveServices.Vision.CustomVision.Prediction.Models.ImageUrl(file.Path));
foreach (var c in result.Predictions)
{
Console.WriteLine($"\t{c.TagName}: {c.Probability:P1}");
}
}
Unhandled Exception: Microsoft.Azure.CognitiveService.Vision.CustomerVision.Prediction.Models.CustomVisionErrorException: Operation returned an invalid status code "BadRequest" Expect a prediction.
