Model builder Error - Unable to find method 'PredictMultiClassClassificationAsync/3' on Microsoft.ML.ModelBuilder.AutoMLEngine

[forReason]

System Information (please complete the following information):

• Model Builder Version: Current
• Visual Studio Version

Describe the bug
I cannot predict from models. Training works fine.
The following error arises:

at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task)
at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)
at System.Runtime.CompilerServices.TaskAwaiter.ValidateEnd(Task task)
at StreamJsonRpc.JsonRpc.d__941.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Microsoft.ML.ModelBuilder.AutoMLServiceFactory.AutoMLServiceProxy.<PredictMultiClassClassificationAsync>d__16.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Microsoft.ML.ModelBuilder.TrainSession.<PredictMultiClassClassificationAsync>d__51.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at System.Runtime.CompilerServices.TaskAwaiter1.GetResult()
at Microsoft.ML.ModelBuilder.ToolWindows.EvaluateTabDataContext.d__93.MoveNext()

To Reproduce
Steps to reproduce the behavior:

1. Go to Solution
2. Richtclick -> Add -> MachineLearning
3. Click on Image Classification, select train data and start trainng
4. Once Training is finished, go to the evaluate section
   
5. Select an image to evaluate -> Error

Expected behavior
Select an image for evaluation or prediction and get a prediction

new project resolved the issue... but its really annoying.

[forReason]

nevermind. when I rebuild and run the Solution, the error reappears at the following line.

public string ClassifyImage(string imagePath)
{
        // Add input data
        var modelInput = new ModelInput();
        modelInput.ImageSource = imagePath;
        // Load model and predict output of sample data
        ModelOutput result = ConsumeModel.Predict(modelInput); // <-- Issue here
        return result.Prediction;
}

System.AggregateException: 'One or more errors occurred.'
Inner Exception
TensorflowException: 2 root error(s) found.
0) Unknown: Failed to get convolution algorithm. This is probably because cuDNN failed to initialize, so try looking to see if a warning log message was printed above.

@forReason thanks for reporting the issue, we will look into it why it happens

[zewditu]

@LittleLittleCloud, could you have anything for the reason of this?

[LittleLittleCloud]

Hi @forReason

It looks like your model is trained by scisharp.tensorflow.windows-gpu, but in .csproj you are referring scisharp.tensorflow (CPU). Could you replace the SciSharp.TensorFlow.Redist with SciSharp.TensorFlow.Redist-Windows-GPU, rebuilt and try again?

Regards

[forReason]

I have changed the Package reference in all .csproj file in the Solution, restarted Visual studio

I still can not evaluate my model. The issue is a different one now:
Error 1:

Sorry for hitting another error!
Did you solve the first issue ?
Could you update your ML.Net Model Builder to the latest version. The issue might be solved in latest version

[forReason]

Yes the first issue is resolved. How would I go about updating ML.Net Model Builder? I have installed it with the Visual Studio installer. I don't think a specific version was selectable there.

[zewditu]

Hello,

Sorry for the late reply !

To update to the latest version in Vs go to Extensions --> Manage Extensions. In Manage Extensions window go to Updates tab then if there is an updated version of ML.Net Model Builder you will see ML.Net Model Builder and update.

@forReason I hope you solved your issue! If you still hit the issue you can reopen it. Thanks
