Absurd error "Error 10: Argument 1 Array must not be empty." RRS feed

  • Question

  • Hi,

    I'm new to ML Studio but I'm really getting crazy with the error in this subject.

    My test experiment on flights delay prediction is perfectly compiled and returns a nice accuracy (nearly 99% on 270K samples).

    However when I publish as a web service (which works) and try to use it, "sometimes" it return the error above.

    However, other times it perfectly works!!

    I don't know if this is the reason, however if I just run an online test and set a parameter to any value between -3 and +3, it works. Instead, if it is 4 or higher (either in positive or negative), the error appears. Since that information just represents the "time in departure", you can imagine that's likely more than 4 (mintues). Anyway I don't catch why I get it, since I never get this error in my experiment even if I run thousand of experiments rather than 1, most of which DO have a value higher than 3.

    Thank you very much for any hint.

    For this issue, you need to check your input dataset, there should be no cell is NA or blank.

  • Hi Mauro,

    Sorry about the issue you are encountering. If the data is not confidential, would you be able to publish a sample experiment that generates the error to gallery in unlisted mode? We could take a look.

    Thank you, Ilya
