I get this onnx from Python but I received error in context.Transforms.ApplyOnnxModel() - "Unable to load DLL 'onnxruntime' or one of its dependencies: The specified module could not be found. (0x8007007E) where is a problem? What should I change?
error

I used before wrong tutorial this work correct https://docs.microsoft.com/en-us/azure/machine-learning/how-to-use-automl-onnx-model-dotnet
added parameters input and output
var onnxPredictionPipeline =
mlContext
.Transforms
.ApplyOnnxModel(
outputColumnNames: outputColumns,
inputColumnNames: inputColumns,
ONNX_MODEL_PATH);
and correct packages
dotnet add package Microsoft.ML
dotnet add package Microsoft.ML.OnnxRuntime
dotnet add package Microsoft.ML.OnnxTransformer
