System.AccessViolationException: 'Attempted to read or write protected memory. This is often an indication that other memory is corrupt.'

I am facing this problem while running Image detection web app. Is there any perticular way to fixed it?

@Anki7s can you clarify which sample you're referring to? Are you hitting this issue when running the ObjectDetection-Onnx sample? If so, the web app or the WPF app?

Pretrained TensorFlow model scoring

I got this error in TensorflowModelConfigurator.cs file.
Here is the code

 var pipeline = _mlContext.Transforms.ResizeImages(outputColumnName: TensorFlowModelSettings.inputTensorName, imageWidth: ImageSettings.imageWidth, imageHeight: ImageSettings.imageHeight, inputColumnName: nameof(ImageInputData.Image))
                .Append(_mlContext.Transforms.ExtractPixels(outputColumnName: TensorFlowModelSettings.inputTensorName, interleavePixelColors: ImageSettings.channelsLast, offsetImage: ImageSettings.mean))
                .Append(_mlContext.Model.LoadTensorFlowModel(tensorFlowModelFilePath).
                ScoreTensorFlowModel(outputColumnNames: new[] { TensorFlowModelSettings.outputTensorName },
                                    inputColumnNames: new[] { TensorFlowModelSettings.inputTensorName }, addBatchDimensionInput: false));

            ITransformer mlModel = pipeline.Fit(CreateEmptyDataView());
