ONNX invalid parameter size. how to solve this?

[adicahyanto]

i'm trying to use an ONNX file in my expert.

my onnx file has 49 inputs at input index 0,

has 3 outputs at output index 0,

and 1 output at output index 1.

when i try to run session

   vector v_input = vector::Ones(49);
   vector v_output(3);
   vector x_output(1);

   if(!OnnxRun(onnx_handle,ONNX_DEBUG_LOGS | ONNX_NO_CONVERSION,v_input,v_output,x_output))
     {
      Print("OnnxRun failed, error ",GetLastError());
      OnnxRelease(onnx_handle);
      return(INIT_FAILED);
     }else
        {
            Print("v_output: ",v_output);
        }

i got error as below:

2023.05.07 04:35:20.074    Core 1    2021.01.27 00:00:00   ONNX: invalid parameter size, expected 196 bytes instead of 392, inspect code 'Experts\ONNX_TEST_01.mq5' (81:65)

i actually only need the output on output index 0. in phyton i could assign unused variable to some random char and just leave it be as phyton will automatically decide the type.

but i don't think that would work on MQL5. as also had tried to assign the output index 1 to some double variable and it just don't work.

could you pointing me out where did i miss?

thanks.

onnx model and mq5 file are attached

You model is expecting float input data type and you provided it double type.

thanks Alain. its working now.

just need to use "vectorf" instead if "vector"
