ONNX sample size and batch size. what are they?

[Javier Santiago Gaston De Iriarte Cabrera]

Hi, I'm having trouble with this:

ONNX.Price.Prediction.Test.mq5

//--- first index - batch size, second index - series size, third index - number of series (OHLC)
   const long input_shape[] = {1,SAMPLE_SIZE,4};

what is the batch size?

from

ONNX.Price.Prediction.Test.mq5

from the shared proyect: ONNX.Price.Prediction

this is the error I get:
