I got the onnx model from tf2. The model infomation is: I load the onnx model follow the document.

private static ITransformer GetPredictionPipeline(MLContext mlContext)
{
    var inputColumns = new string[]
    {
        "model"
    };

    var outputColumns = new string[] { "dense" };

    var onnxPredictionPipeline =
        mlContext
        .Transforms
        .ApplyOnnxModel(
        outputColumnNames: outputColumns,
        inputColumnNames: inputColumns,
        ONNX_MODEL_PATH);

    var emptyDv = mlContext.Data.LoadFromEnumerable(new OnnxInput[] {});    //the line will throw the exception

    return onnxPredictionPipeline.Fit(emptyDv);
}

when i ran the app,I got the exception at the line.

System.InvalidOperationException:“Input shape mismatch: Input 'model' has shape 1,50,4, but input data is of length 1.”

I have tryed many time to resove the problem.but it just can't work!

@zhangfeibao what does your ONNXInput class look like?
